If so, can new wearable/smartphone medical technology be effective for that population [...]
It is well documented that health care reimbursement is moving away from pay-for-service and toward pay for efficiency, quality, and improvement in outcomes. There is tremendous pressure to lower hospital readmission rates. Can medical device design add value within this new paradigm? Absolutely. A medical device that is well-designed will be easy to use. It [...]
As I wrote in May, the biggest constraint in any kind of medical device design today is battery technology, which has not kept pace with the progressive aspects of medical devices. But energy-harvesting technologies for use in wearable designs show promise, in spite of four key engineering challenges: 1) the power they generate; 2) how [...]
One of the most exciting developments in medicine and science is the possibility for humans to be able to control computers with their minds. In fact, it’s no longer just a possibility, it is actually being done. The NY Times recently had an article about an armless man who can control a pair of robotic, [...]
Medical Marketing and Media (MM&M) has an interesting article regarding MannKind Corp’s Afrezza inhaled insulin. Initial roll-out of the therapy has been below expectations. One of the reasons for that, the article contends, is that the Afrezza therapy has not yet proven that it will provide increased value over other current therapies, pen injectors, for example. [...]
There are many new technologies in the development pipeline – and coming on-line – that will be incorporated into new medical devices in amazing ways. Unfortunately, advances in battery technology have not kept pace with advances in functional capabilities, miniaturization, and other areas. Often, the element that constrains design the most is the size of [...]

This past year has seen a number of advances in flexible electronics that conform to the curves of the human body and stretch and move with [...]
Medical device designers are very passionate about what they do. We tend to get caught up in the object we are designing. How to make it beautiful, effortlessly usable, the greatest thing ever. As well we should. To most everyone else though, the thing we’ve so thoughtfully designed is just a lump of technology. It [...]
I have been writing quite often recently about how medical research is focusing more and more on the brain. There is yet another story that highlights this trend. But there is another, more intriguing aspect to the story that portends a different impact. Via MedGadget, we learn that the company, NeuroVigil, has partnered with the American [...]
Each image is of the same exact neurons of a genetically defined group of cells. But some (left) fire while mice search for food; others (right) fire while the mice eat food. (credit: Garret Stuber, PhD) I believe that research into how the brain works is going to be a major focus [...]
“New fibers can deliver many simultaneous stimuli. Implanted into the brain or spinal column, they can transmit drugs, light, and electrical signals.” MIT scientists have developed a process by which they can produce flexible, multi-channeled polymer fibers that could simultaneously deliver drugs and optical and electrical signals. The polymer itself has characteristics that resemble human neural [...]
When doing product user research, a lot of designers make the mistake of assuming the problem to be the first thing their users articulate. Henry Ford is purported to have said, “If I had asked people what they wanted, they would have said faster horses” (in fact, that is the problem that Ford addressed. He [...]
I have written on a number of occasions about Optogenetics and its promise for medicine. Here is another story, via Medgadget, that reports on advances in the field. In summary, scientists were able to use optogenetic techniques – which allows light to stimulate specific brain neurons – to induce REM sleep in mice. How might these advances [...]
I recently experienced today’s health care system first-hand from the patient’s perspective. One of the things that struck me was the amount of improvisation that took place in order to devise solutions for which a dedicated product wasn’t available. For example, showering with an IV line in place. In order to keep the IV dry, [...]
“Experience Design” has been a methodological approach used in the consumer products industry for some time. Apple pioneered the practice, deliberately designing not only the product itself, but every aspect of the user’s interaction with it, from opening the package and removing the product, to setting it up, turning it on and using it for [...]
MedCity New reports on a study by A.T. Kearney that has some interesting findings for medical device design: The analysts say that the “emerging markets will save us” theory is false.

Following is a summary of the most important points contained in [...]
An interesting article in fastcodesign.com talks about social science research into what makes one thing seem “cool” and a similar thing not. Cool is a perception, not an inherent quality. It’s established in a very social process wherein a society’s trend setters adopt it (who determines who the trend setters are?), then it’s taken up by [...]
Personal fitness trackers are the rage right now. One of the hopes for these types of devices is that the data will be able to be used by physicians to keep their patients healthy. But will the data generated be of any use to the healthcare ecosystem? A recent article in Venturebeat suggests not: “… sources [...]
A recent article in the New York Times was about how Apple uses some Picasso lithographs to illustrate to their employees how simple design is created. Simple – meaning no frills – design is the basis of the Apple design aesthetic. The simplicity aesthetic originated with Dieter Rams’ work with Braun. It’s an aesthetic and [...]
3D printing’s greatest advantage is in the flexibility it allows in part design – parts with undercuts and zero draft can be manufactured.

OMsignal claims the shirt will be able to track movement, respiration and heart activity. Another company, Hexoskin has a similar product already on the market. According to a blurb on their website, "They envision a future [...]
One of the reasons products fail is because they’re designed as objects in isolation, without considering the context in which the object will be used. Design should be done in consideration of the whole system in which the object exists. The designer should also focus not on the object as much as what the object [...]
Testing and diagnosis is moving out of the lab and to the point-of-care. One recent example of this is the device that QuantuMDx is developing: a handheld molecular diagnostic and sequencing device to deliver rapid disease diagnosis at the point-of-care. Their goal is to enable routine real-time personalized medicine with a simple device that can deliver DNA [...]
The company, DataArt, is developing technology that will take an image of the food you eat and look up the calorie content. This approach is a logical next step in passive acquisition of caloric data, but it seems inelegant and cumbersome. With the advances in sensor technology that are taking place, it shouldn't be long until [...]
Tiny increases in sweat gland production translate into large changes in skin conductance. This phenomenon is being used to study the medical implication of increased sweat production. Rosalind Picard, of MIT, has been using data from body-worn sensors to measure and correlate emotional states.

Recently, New York Times journalist, Albert Sun, published an article about his experience with fitness tracking devices. His original idea was to compare various trackers to see which ones were the most accurate. He realized that the compelling aspect of such trackers was not in the data they accumulated and how accurate that data was, but [...]
Patient accountability/partnership will become the norm. Preventative care and early diagnosis will be the focus. Biometric data tracking will be used to establish a “digital you” against which predictive models can be run to forecast health risk so preventative measures can be taken. Everything will be connected and interactive. Surgical intervention will become increasingly minimally invasive. Nano robots [...]
Many companies are introducing wrist-worn bands that track your activity levels, calculate calories burned, monitor your heart rate, etc. One drawback to the wrist-worn form factor is that it limits the skin surface area that can be used for sensing. Flexible electronics are being developed that can conform to body contours. As this type of [...]
Optogenetics is one of the most interesting and promising of the new technologies in science and medicine. It involves modifying DNA with genes that make light-sensitive proteins. Modifying neurons in this way makes them react when energized by light. Most experimentation to date has focused on understanding how neural systems work and how they might [...]
An article in MedCityNews highlights an interesting point regarding wearable health sensors and the data they generate: how do users make sense of all the data they collect? This quote, from Catherine Calarco of Heartmath is telling: “People are still trying to figure out the design and presentation of the data. I’d like to see more user [...]
Here is an interesting example of use patterns impacting results: The Pecan Research Institute ran a study in which they analyzed electricity generation by solar panels that a) faced south and b) faced west. Most solar panels are mounted to face south because that orientation maximizes the number of hours of sunlight the panels can receive. [...]
Resistance New ideas can be threatening, and they can provoke a negative reaction. There is actually a bias against creativity. Most people will say that they value creativity. And they really believe that they do. But in fact, we harbor a bias against creative solutions in favor of those we perceive as safer and more [...]
When you exercise your muscles, you don’t see immediate gains in strength. It’s only after you’ve rested that the strength gains occur. Neuronal connections seem to act similarly. When you’re thinking hard about a problem, it’s rare that you’ll have a eureka moment. The insight usually comes only after you’ve let the problem ruminate in [...]
Why do most people find it hard to be creative? One reason is that we’ve spent our lives learning how to be logical and analytical. To think creatively, you have to stop thinking logically. The emphasis on logic and analysis works well for helping us navigate most of the problems of our day-to-day world. But [...]
When it comes to creative problem solving, we often assume constraints that aren’t actually there. Here is the iconic creativity problem: Draw four straight lines through the nine dots without retracing and without lifting your pen from the paper. The solution to this problem can only be found by going outside the [...]
Non-invasive testing is a growing trend in medical device design and development. A new technique that uses sound to detect the presence of malaria has been developed by Drs.

How we perceive a problem governs our approach to it. The words we use to describe a problem affects how we think about it. WORK YOUR WAY THROUGH THE MAZE FROM POINT A TO POINT B: (from A Whack on the Side [...]
Last week I presented a problem to illustrate how rearranging the components of the problem can help you see in different ways to develop creative solutions. Here’s the solution: When you view the links in the context of a square, an obvious solution presents itself: break 4 links, weld 4 links = $20. But changing [...]
Medical devices that use smart phones as part of their base technology are becoming more prevalent. And we are seeing more such devices being marketed to consumers, not just to the scientific community. This trend will be a boon for those in medical device design. One of the latest devices in development makes use of [...]
My last post introduced the idea that creativity can be enhanced if you deliberately look at things in different ways. Rearranging the components of the problem is one technique for doing that. In our design practice, we find that putting together quick prototypes using paper or styrene foam or other easily cut and glued materials [...]
Edward de Bono coined the term “Lateral thinking”. He has published a lot on thinking and creativity. Per Dr. de Bono, the majority of mistakes in ordinary thinking are mistakes in perception. Our traditional emphasis on logic does little for perception. If the perception is inadequate no amount of excellence in logic will make up [...]
Why is it so hard to generate creative ideas? Three reasons: perception, rules, logic. Perception: It’s difficult to see things in ways we’re not used to Rules: We box ourselves in by assuming rules that really aren’t there. Logic: Our emphasis on logical thinking works well for helping us navigate most of the problems of [...]
The next significant development in the self-monitoring arena is going to deal with service, not hardware. What Alivecor is doing with their iphone ECG device presages what other companies will be doing with their monitoring devices in the near future. Alivecor has added a service whereby a person’s ECG can be read and interpreted by an [...]
My last post discussed a technique called “laddering up the benefits”. Another technique that will help you see problems from a different view point is to rephrase the question putting emphasis on different parts. Consider this problem statement: “How can a surgeon apply surgical sealant with maximum control?” Normal emphasis is on the word, “how”. [...]
Here is a fresh article from Treehugger about a clever idea out of Russia: Do 30 squats and get free subway fare. It seems like a great way to incentivize people to exercise. I would certainly exercise more if I got paid for it.
In my last post I wrote about how problem finding is an important precursor in solving medical product development problems creatively. One technique you can use to better understand the true problem you are facing is to “ladder up the benefits”. The technique involves examining a problem in a step-wise fashion by asking, “If I [...]
In research done more than 50 years ago, Jacob Tetzels and Mihaly Csikszentmihalyi at the University of Chicago demonstrated that people who focused on FINDING problems were more creative (and were ultimately more successful in their creative endeavors) than those who focused solely on SOLVING problems. Their test was to have a group of art [...]
What makes some people more creative than others? Is creativity innate or can it be learned? Why are children so creative? Why do we seem to lose our creativity as we grow older? Those were some of the questions we explored in our workshop at MDM Chicago 2013. I love this quote, attributed to Albert [...]
This past week we conducted our workshop, “Break on Through to Creativity”, at MDM Chicago 2013.

The shrinking size of sensors and electronics, combined with new power technologies, will enable fitness tracking devices and other monitoring medical devices to be designed more along the lines of jewelry . Modularity and customizability will be the key to success here. One aesthetic will not appeal to everyone. Offering a system that allows base [...]
There is an interesting story at MedCity News. Seems that CVS is trying to get their employees to take an active role in their own health by encouraging them to live more healthy lifestyles. Several groups are calling the CVS program an invasion of privacy. I believe that we will be seeing more companies adopt [...]
Last week I wrote about the medical device technology I think will advance in 2013. Two of those areas are flexible electronics and controlling devices with our thoughts. Well, how about combining those two ideas? Business Insider reports on just this scenario. Work is being done by MC10 and by NorthwesternUniversity and University of Illinois – [...]
From Northwestern University comes news of a battery that can be bent and stretched. This is exactly the kind of development that will speed the commercialization of flexible electronics (in fact, the stretchable battery uses some of the same techniques as those used in flexible electronics). The current iteration of the battery can power an LED [...]
In previous posts, we have taken a look at general trends in medical device design and medical technology. What about the near term future of 2013? In the coming year, I think we’ll see a lot of news regarding: Devices that attach to smart phones. Devices in development that incorporate flexible electronics. Progress in the [...]
Two stories in the last two days illustrate that the genomics revolution in medicine is gathering speed and is about to deliver tangible benefits. The Tampa Tribune (via Medcity News) reports about a team of researchers that has found that persons with a certain genetic signature can prevent fatal heart arrhythmias by using a specific beta-blocking [...]
Those of us involved in medical product design and development spend a lot of time thinking about product appearance and about how the user will interact with the product. As it relates to medical industrial design, these activities are at the heart of what we do. There are many methods, processes and techniques we employ [...]
One of the newer ideas floating around is to make electronic health records work like wikipedia-style (semi)open-source documents. A person’s medical record could be accessed (with permission) by doctors and updated with new information. That way, there is one master record that is continually updated and current. This is a great idea on its surface, [...]
Medical products are often used in stressful situations. Stress reduces cognitive function. In that environment, the importance of good design that helps products be intuitive to use should be apparent. Medical product design that achieves this can only be done if the designer understands human perception and cogniton As more medical products move from the [...]
Will graphene be the material that powers the future? Batteries are the bane of medical device design and development efforts. Heavy, inefficient and toxic, batteries are often the constraining factor in a medical product design. Form factor is often influenced largely by battery size and placement. Now, graphene might be able to be used as [...]
A number of hospital systems are establishing centers to help launch med-tech startups. The Cleveland Clinic is a pioneer in this area, with their Innovations Center. St Joseph Health has just launched the Innovation Institute, the heart of which is the Innovation Lab, which will incubate inventions that have come from the health system’s staff. [...]
I posted a blog yesterday about personal diagnostic devices that will couple with smart phones. The latest is a metabolism tracker (courtesy of MedGadget). That didn’t take long.
Smart phones are becoming ubiquitous. Devices that attach to smart phones are being developed by more and more companies. In the medical device field, a number of such products have been released in the past year. As this trend progresses, I believe we will see the advent of personal diagnostic devices. That is, lab-on-a-chip devices [...]
Just two weeks ago, I posted an entry that spoke about how new medical devices would incorporate smart phones as integral components of their technology. The latest is the iExaminer from Welch Allyn:
It seems that instituting electronic medical record systems has not brought about the savings originally predicted. It seems that the systems were designed primarily to help providers increase billings, not to improve patient care or save money. And it seems that the Health Information Technology industry has done quite well in the EMR roll-out. What [...]
When you are designing displays and interfaces on medical products, simplicity goes a long way in making the device easy to use. Every piece of visual information competes for our attention. It taks a lot of cognitive energy to decide what are the important things we need to pay attention to at the moment, when [...]
I am intrigued by a story in the New York Times (Jan 17, 2013), about someone who was able to use anonymous genetic data posted online to determine the identities of the those whose dna sequences were published. The implication is that disseminating genomic data will compromise individual privacy unless a strong security protocol is [...]
Technology that allows computers and even mechanical devices to be controlled by thought is advancing at a remarkable pace. The latest development comes out of the University of Pittsburgh , where a woman with quadriplegia has been able to control a robotic hand via her thoughts, an implanted electrode grid, and an algorithm that translates [...]
I recently wrote about how medical product design was evolving to base signal processing and user feedback functions on smart phones. As further evidence of this trend, Variable Technologies has introduced their NODE product – a small tubular device to which various sensor modules can be attached. The sensors send their data via bluetooth to [...]
The trend right now is toward wearable sensors and medical devices that can monitor our physiology, enabling us to reach health goals and warn of impending health problems. This is the next stop on the way toward technology that we don’t carry around with us at all, but that is part of our environment. There [...]
MC10 is at the forefront in developing flexible electronics that can be applied to the skin like a sticker. There are many areas in which flexible electronics will serve as a catalyst for innovation, but their use in the design of medical devices is especially promising. Continuous monitoring of vital signs and other physiological processes [...]
Pertinent to a very recent post , UCLA has announced an allergen testing device that attaches to an iphone. Medical devices that attach to smart phones are becoming more commonplace. What most of these devices provide in terms of power and convenience, they lack in elegance. For devices that couple with something as personal as [...]
If a product is easy to use, it makes the user feel competent. Feeling competent is one of the most critical factors in being motivated to continue a task. Being frustrated leads to feeling incompetent, which in turn leads to abandonment of the task. That is why ease of use is so important in the [...]
A shift is taking place in medical product design. A number of companies have released devices that attach to iphones to complete their functionality. Alivecor has an add-on that enables the phone to act as an ECG monitor. Dermlite has an attachment that allows dermatologists to more efficiently diagnose skin cancers. There are a number of other [...]
Misfit Wearables will be coming out with a fitness tracking device in 2013 that is more or less a piece of jewelry with technology inside. The device tracks your movement (running, cycling, swimming, etc.) but the only feedback it provides is via a series of small led’s that tell you how far you’ve progressed in [...]
A transition is definitely taking place in the way we interact with electronics. We are moving form using keyboards, mice and graphical user interfaces to using voice, touch and gestural movement. How will this impact medical device design, and what do we as designers need to be aware of moving forward? Remarkably, touch capacitance works [...]
Medical device design for surgeons, nurses and others in the medical professions requires that the designer understand how these specialist populations use the devices that are unique to their specialties. The techniques that doctors and dentists use with specialized injection devices, for instance, is often not obvious to the lay person. It’s essential that direct [...]
Oregon State University reports that they have developed a technology that allows them to integrate multiple sensors onto a single microchip. The sensors replace what are currently large components in devices such as body-worn pedometers and fitness trackers. Rather than large, expensive, power-hungry devices, the OSU technology could accomplish the same sensing function in a postage [...]
Intuitive Automata, Inc. will be introducing a robot – Autom – that will act as a personal weight loss coach. Medgadget has the details. This is the latest development in harnessing technology for wellness. Previously, we’ve noted that companies were turning toward applications that use gaming and reward systems to encourage attainment of health goals. It [...]
Medical product design is going to have to respond to increasing pressure on product cost. A medical product’s effectiveness/cost ratio is going to be a crucial benchmark as the healthcare delivery market is pressured to move from a fee-for-service model to one that rewards positive outcomes. Rather than working toward innovative advancements in treatment, companies [...]
Medical product development companies are beginning to pay attention to the ecosystems that surround their products. A narrow focus on the device itself is giving way to a more wholistic approach, one that encompasses not just the product but also the patient experience, the overall procedural efficacy toward which the product contributes, and the economics [...]
A revolt is fomenting within the design community. Researching and knowing the user has been a foundational priniciple of best-practice product design for some time. Now, however, I’m hearing with greater frequency the opinion that soliciting feedback from users doesn’t give you the answers you need. That users don’t really know what they want. That [...]
There is a growing need for medical product development to include aesthetics as one of the prime drivers of product success. We have noted for some time that medical products and devices are moving out of the hospital and clinic environment and into the home, and even into public spaces. As further proof, the Federal [...]
In medical product development, one of the most significant challenges involves satisfying the power requirements of devices. This is particularly so with implantable devices, where replacing batteries requires a medical procedure. There are several intriguing technologies that are being researched to see if power can be provided by the human body’s own systems to drive [...]
Medical product development is too often limited by focusing solely on the medical product or device itself. A serious medical product development effort provides the opportunity for design to influence many elements of the overall system of purchase, use and disposal surrounding the product. For example, “priming” is a concept in cognitive psychology that contends [...]
Medical device design is at the forefront of commercializing radical new technologies. A little over two years ago, we posted about new technologies that were being developed to monitor blood glucose levels non-invasively . Now, C8 MediSensors, has incorporated one of those technologies – Raman Spectroscopy – into a device that has received CE approval. [...]
Medical products are not used in isolation. I keep a picture of a crowded operating room on the wall of my office to remind me of the mess that is the environment in which most medical products are used: To maximize the usability [...]
Many companies are realizing that industrial design offers them a competitive advantage. This is just as true with medical products. Companies will realize competitive advantage if they employ design as part of their strategy. There is a clear trend toward limiting hospital stays. As a result, medical products of all kinds are being used more [...]
In medical product design, Cognitive Load is an important concept to be aware of. Visual complexity is an enemy because it overloads our ability to mentally process all the information we are taking in. Not only is it difficult to process a lot of information at once, having too much information to choose from inhibits [...]
Masimo has announced a “resposable” pulse oximetry sensor that reduces environmental impact by 90 percent. This is clear evidence that medical device designers are responding to market demands for environmentally friendly products. Reducing carbon footprint will become a significant criteria in medical device design projects moving forward.
The last post looked at how medical product design can be done in such a way as to motivate the user to prefer one product over another. Motivation also comes into play during the use of the product in that we are motivated by progress, mastery and control. Small signs of progress can have a [...]
Another facet of cognition that medical product designers should understand has to do with motivations and desires. Though we learn to hide it well, at the most basic level we all harbor doubt, fear, insecurity and a sense of incompleteness. To counteract those feelings, we are drawn to objects that reflect our view of our [...]
We process information best when it’s presented in story form. “Let me tell you a story…” is a powerful way to grab people’s attention. Because stories normally progress in a linear fashion, they imply that one event leads to another, that there is causation. Just as our visual system seeks to detect patterns that allow [...]
It is important that medical product designers not make assumptions about users. What might be obvious to you as the designer might not be obvious to those using what you’ve designed. People will always make mistakes. It’s impossible to design a perfectly fail-safe system. The approach to take is to anticipate as much as possible [...]
Please forgive me, but some things just can't be left unchallenged: The new Caimen 5 Vessel Sealer from Aesculap..... Looks like a squirt gun a circus clown would use: Yes, by all means, let's put a gun in a flower! [...]
In medical product design, function is paramount. The device must work as intended, no questions asked. Proper function is often related to operation of the device in the proper manner. Designing a medical device in a way that clearly shows the user how to operate it must employ a knowledge of cognition as a basic [...]
A number of medical products have come out in the past year that provide their functionality by coupling to smart phones. One device enables remote dermatology diagnosis. Another provides an add-on that can diagnose an ear infection. Still another turns an iphone into a microscope. We will undoubtedly see more such devices. For medical device [...]
In recent posts, we have been considering how medical product design can use knowledge gained from the field of cognitive psychology to suggest ways in which medical products and devices can be designed so they are more effective for users. We have written a lot about how the way in which we see influences our [...]
(Another in a series about how medical product design is informed by the science of cognition.) We want to see patterns and we like to create categories. If the designer doesn't provide informational categories, we will make our own. We want to create order. Patterns imply order, so that is what we look for. Medical [...]
It’s important in medical product design to understand that users will not always pay attention to visual cues the designer provides. Critical cues must be exagerated or given a treatment that draws attention in an obvious manner. Our eyes are drawn to contrast – both in color and in value (dark vs. light) – and [...]
The last several posts in this series have considered various aspects of the way we collect and interpret visual information and how that impacts medical product design. Another characteristic of our visual sense that is not often considered is the importance of peripheral vision. Whereas we use central vision to recognize specific objects, we use peripheral [...]
Medical device development using nanotechnology systems and techniques is just getting started. North Carolina State University will lead a National Science Foundation Nanosystems Engineering Research Center that will investigate and do basic research on self-powered health monitoring. The program is called ASSIST, for Advanced Self-Powered Systems of Integrated Sensors and Technologies. Funded by an NSF grant [...]
Last time, we talked about visual simplicity and how that relates to medical product design. In some respects, our desire for simplicity conflicts with our desire for control. We equate having choice with having control. Our need to control the environment is built into us, the hypothesis being that as we evolved as a species, [...]
Medical product design is going to be impacted greatly by new technologies that are being developed to allow non-invasive testing and monitoring of things that now require finger sticks, blood draws, and other unpleasantries. We’ve written in the past about various technologies that use light, and microneedle sensors, to accomplish this. Now, microelectronics are also [...]
(This is the fourth in a series about cognition and how it relates to medical product design). Effective medical product design is that which reduces complexity. Experiments have shown that we can hold only 3 or 4 pieces of information in working memory at one time. By designing to this limitation, you won’t overload the [...]
(This is the third in a series about cognition and how it relates to medical product design). The last post talked about how our minds can fill-in visual information that’s missing. Just as we can add missing information, we can also filter out information that we don’t need. Perception is selective. We naturally filter information [...]
(This is the second in a series about cognition and how it relates to medical product design.) When we interact with a surgical tool, medical device, lab instrument or any object, our first impression will most likely be visual. We’ll see the object and then begin to make sense of it and understand how to [...]
This is the first in a series of posts that will discuss the ways in which we perceive, think about and make sense of the world, and how that relates to medical product design. Medical product design has a lot to do with embodying devices with characteristics that make them easy to understand and to [...]
Incorporating genomics technology will be increasingly important for medical product design as the cost of sequencing and analysis falls. In the coming years, we will see amazing new devices that utilize some form of genomics technology as their foundation. This amazing story, that I picked up from MedCity News, confirms how genome sequencing is going improve [...]
A promising area of medical technology is emerging in which medical device design will be able to make a major contribution. We’re seeing a number of companies that are working on technologies that enable nearly instant diagnostic test results. Epocal is one, Abbott is another. Most of the focus seems to be on bedside administration, where treatment [...]
Medical device product development is advancing with the help of sophisticated computational algorithms that translate signals detected by non-invasive electrical and optical sensors into meaningful health data and images. We’ve written before about how computing power is being used to augment and magnify the relatively crude information that current sensing technology can gather. Reflectance Medical [...]
Medical product design will be faced with many challenges as the U.S. population ages. There are trends that suggest that remote monitoring via sensor systems, care at home, and virtual coaching will all be areas in which there will be significant opportunity for innovative medical product design to have an impact. The trend toward care [...]
Medical device development will increasingly be driven by the growing amount of health data that is being generated. Even companies not traditionally in the device industry are realizing that they too will be impacted by the data deluge: For Craig Lipset, Head of Clinical Innovation for Pfizer, the future of pharmaceutical companies lies in [...]
If you’re involved in medical product design, Medcity News is an excellent resource for keeping up with what’s happening in the medical device industry. Here is a link to an important article about patients and connected care that speaks to health data/information technology, electronic medical records and most importantly, preventative care.
Continuing on the subject of health data – which was the big theme at the 2012 CONVERGE Summit for Healthcare Innovation – Brandon Rowberry, VP of Innovation Development at UnitedHealth Group, made the point that the challenge for innovators in the medical device and healthcare fields will be in digesting the mountain of health data [...]
According to Dr. David B. Nash, Dean of the Jefferson School of Population Health, the healthcare economy is changing from one that encourages service volume to one that encourages better health outcomes. His mantra for the future is, “no outcome, no income”. This was the gist of Dr. Nash’s talk at the 2012 CONVERGE Summit [...]
What are the most promising avenues for medtech investors? That was the question discussed by a panel of entrepreneurs and venture investors at the 2012 CONVERGE Summit for Healthcare Innovation. It seems that medical product design could become dominated by software. Echoing the conference's overall theme of data, the big players are looking for digital [...]
Telemedicine will be a fertile area for medical product design. The two biggest challenges in telemedicine right now are the difficulty in getting reimbursement for telehealth services and barriers created by inadequate cross-state licensing. From the Telemedicine breakout session at CONVERGE 2012: It’s difficult to get reimbursement for telemedicne practice because its benefits are as [...]
What will be driving healthcare innovation in the coming years? According to Kevin Schimelfenig, Dr. Ken Riff, Kem Hawkins and Richard Russo, panelists at the 2012 CONVERGE Summit for Healthcare Innovation, this: Innovation is needed in the process of care delivery. There are opportunities for big improvements in access, cost and quality. Markets outside the [...]
In the days when the sea was the best means of traveling long distances, the economic success of a country was heavily dependent on the geographical reach of their maritime trade and of their navy. Scurvy was one of the biggest killers aboard ship and limited the time a sailor could remain at sea. Finding [...]
The future of medical device design lies in harnessing the massive amounts of health data that will be generated in the coming years. Other take-aways from the 2012 CONVERGE Summitfor Healthcare Innovation: Business models will need to change. Healthcare players are moving to expand their reach within the continuum of care. Improving patient outcomes: all [...]
Data. That was the overarching theme of the CONVERGE Summit for Healthcare Innovation held in Philadelphia on July 10th. This quote from Dr. Ken Riff of Medtronic struck me in particular: “ data will be the healthcare currency of the future”. What implications does this have for medical device design? It will take time to [...]
If you want to know where those at the forefront of the rapidly changing healthcare landscape see both disruption and opportunity, check back here. I am just returned from the CONVERGE Summit for Healthcare Innovation presented in Philadelphia by MedCity News. The agenda was jam-packed with excellent speakers and panel discussions about exciting developments and trends [...]
The use of body-worn sensors to monitor physiology and provide usable feedback to individuals is still very new. Most of the devices we’ve seen so far track such things as heart rate, body temperature, respiration rate and calories burned and are used mostly as athletic training aids and weight-loss aids. Now, Orpyx is working to release [...]
I have written before about how computers will be used to enhance imaging data to give us a much clearer view of human physiology. The newest example of this comes from MIT, where researchers have been able to enhance video to reveal subtle movement and color changes that heretofore could not be visibly detected. See [...]
If you’re interested in keeping abreast of innovation and future trends in medical device design and in the medical field in general, the CONVERGE summit for healthcare innovation happening on July 10, 2012 in Philadelphia promises to be valuable. I will be attending and will be reporting in future posts about what I learn. Click for [...]
Medical device design, to be successful, must start with a crystal clear understanding of the true problem the device will be designed to solve. This quote, from Sonny Vu, in an article at MIT Technology Review, superbly illustrates the point: “If you have diabetes, what’s your main problem? It’s that you don’t want to have [...]
Controlling computers using the electrical impulses from your brain seems to be making advances. PSFK reports on two companies, Emotive Systems and NeuroSky, that have developed headsets that allow users to control video games with their thoughts. The actions the devices allow are at present very limited, but indicates that the technology is definitely moving [...]
A recent article in the New York Times points to a study of 53,666 sets of identical twins that looked for genetic predictors of disease. Turns out the study found little value in using genetic makeup to predict disease. An interesting finding, but not surprising, as the field is still in its infancy. As gene [...]
We’ve been hearing a lot about “gamifiication” to get people to engage in a variety of behavior-change exercises. Does turning something into a game provide sufficient motivation? For some people it probably does. For others, not so much. MIT’s Technology Review recently ran a story about a company that is developing devices and a virtual [...]
There was a story in my local paper recently about how a nearby town’s (Wake Forest, NC) wellness program has helped decrease the town’s insurance rates by 4.3%. Since the wellness program started in 2007, the town has gotten $75,000 in insurance credits, high-dollar claims have decreased and annual health care costs have leveled off. [...]
MIT’s Technology Review recently ran a story about a company that hopes to dramatically increase the speed of analyzing a sequenced genome. We’ve written in the past about how genome sequencing is getting faster and less expensive, but it still takes a year to do the analysis on the genome to derive any useful information [...]
Our health care system is expensive largely because it is reactive, attempting to correct problems that have already occurred. And those problems are often the result of long-term neglect on behalf of the patient. Our health care system would be much less expensive if its focus became predominantly proactive: aimed at keeping people healthy. This [...]
Most of us are familiar with Maslow’s hierarchy of needs that progresses from the most basic physiological needs up to the needs of self-actualization. A similar thing is going on with respect to products. That is, users have different needs relating to the products they use. The lowest level is function: the user just wants [...]
“Good design is as little design as possible” – Dieter Rams Dieter Rams is an icon of design. His work is based on simplicity and economy. Many of the designs he did for Braun in the 1960’s are as fresh today as they were then. Medical device designers can learn a lot from the way [...]
The TedMed 2012 conference was held last week. I was not able to attend, but the reports I’ve read indicate that preventative health was a big topic. In fact, of the 50 challenges proposed in TedMed’s Great Challenges program, the challenge voted number one was “inventing wellness programs that work”. From the TedMed.com challenges brochure: [...]
Taking responsibility for your own well being is going to be almost mandatory in the future. No longer will we have the luxury of being passive consumers of healthcare managed and directed by others. Preventative healthcare will be extremely important. We will need to be active participants in our own care, and we will need [...]
PBS has documentary about several health systems in the US that are delivering quality health care to all citizens at the lowest cost. You can watch it here. There are a number of aspects that make these systems work in reducing health care costs. Chief among them is the fact that they focus on providing [...]
New information out of the University of Pittsburgh reinforces what we have been saying about enhanced imaging techniques: computer analysis will be used to augment imaging technologies to provide far greater clarity than we can achieve presently. The technique being developed at Pitt uses algorithms that analyze MRI scans to create brain images of neuron [...]
Medtech Insider points to a study just released by Ernst & Young that provides more evidence that what we have been saying for some time now is gaining acceptance: the best way to drive down health care costs is to engage in preventative care so that people remain healthy longer. The E&Y report emphasizes that [...]
Microsoft and GE recently announced partnership in their “Caradigm” venture, scheduled to launch in 2012. From the press release: “Caradigm will be aimed at driving a paradigm shift in the delivery of care by enabling health systems and professionals to use real-time, systemwide intelligence to improve healthcare quality and the patient experience. Upon formation, the [...]
Your own health, that is. The days of trusting your care solely to your doctor is quickly coming to an end. We’ve been saying this for awhile, but more and more people are picking up on the fact that patients will need to become partners in their own health care. Medical insurance premiums are not [...]
That is what Andreas Sundquist of DNAnexus predicts we will be able to put together within ten years. That’s a fascinating prospect in itself, with far-reaching ramifications. But Sundquist’s real point is that DNA sequencing is poised to become routine. He thinks that by 2014, we will have sequenced a million human genomes, tens of millions [...]
In the coming years, we will be hearing a lot about coordination of care. Two recent items highlight this trend. First, is the concept of the patient-centered medical home (PCMH). Basically, the PMCH model calls for each patient to be under the care of a personal physician who is responsible for coordinating that patient’s care [...]
More and more devices are showing up that track your vital signs, calories burned, etc. etc. As we’ve been predicting, personal informatics is gaining ground in the popular culture as a means of staying healthy. This is a subset of the move toward preventative care, which will become more and more important as the costs [...]
Most people will say that they value creativity. And they really believe that they do. But new research out of The University of Pennsylvania, UNC-Chapel Hill and Cornell shows that, in fact, we harbor a bias against creative solutions in favor of those we percieve as safer and more practical. The reason is because most [...]
Last year I wrote about how new technologies combined with software data enhancement will revolutionize medical imaging. A new development in this area comes out of Imperial College London and the Agency for Science, Technology and Research (A*STAR). Scientists there have found a way to make electromagnetic terahertz waves (T-rays) much stronger while requiring less [...]
In a post last year we noted that the cost of sequencing an individual’s genome was expected to drop to $100 and take less than ten minutes. We’re not there yet, but Life Technologies has announced that they will be introducing an instrument in 2012 that can sequence a genome for $1000 and do it [...]
A question was posted in one of the on-line groups I participate in: what purpose does beauty serve in the design of a product, and what value does it have? Behind the question seems to be the presumption that, in many peoples’ eyes, aesthetics is a secondary consideration to function. In medical product design that [...]
Real-time monitoring of body chemistry using microneedle sensors might be coming soon, thanks to researchers at North Carolina State (ok, more accurately, the Joint Department of Biomedical Engineering, University of North Carolina and North Carolina State University), Sandia National Laboratories and University of California, San Diego. The press release explains that an array of hollow [...]
This one doesn’t have much to do with medical device design per se (other than enabling you to imagine how far and how quickly robotic surgery will be advancing), it’s just cool. Check out this video at Medgadget.
There have been a number of recent stories in the medical press regarding developmental systems that enable direct control of both software and hardware devices using brain activity alone. I wrote about some of those systems here. The technology seems to be advancing quickly and has the promise of making real what was just recently [...]
Medical device development is rapidly advancing in the area of wireless health monitoring. In a move targeted at medical device designers, Freescale has just introduced the Home Health Hub (HHH) reference platform. From their press release: “Freescale’s HHH reference platform provides comprehensive functionality and can be used as the foundation for connected medical product designs, [...]
Medical device design continues to benefit from advances in sensor technology. A sample of recent news: Everest Genomics recently announced that it will be releasing its CardioDefender diagnostic system: a wrist-worn ECG sensor device that communicates wirelessly with a smartphone. The system will allow real-time, long-term monitoring to detect, analyze and report heart arrhythmias. BAM Labs [...]
I was going to wait until next week to post on the many recent developments that have come to the fore regarding non-invasive sensing of physiological functions and how that will impact medical device design. But this article by Frank Moss from yesterday’s NY Times is too timely not to give a shout-out too. It’s also [...]
My second big take-away from Ibiliti’s 2011 Medtech conference was from remarks given by Dr. Ralph Snyderman, Cancellor Emeritus for Health Affairs, Duke University School of Medicine. Dr. Snyderman spoke about how, within ten years, the delivery of medical care will be vastly different than it is today. This has huge implications for medical device [...]
If you’re involved in medical device design, the annual Medtech conference put on by Ibiliti is a great forum for learning about current issues in the field. Their 2011 conference was held on November 1st and 2nd in Chapel Hill, North Carolina. This year’s event was again very informative, with a good cross-section of speakers [...]
The New York Times reports that Massachusets is working on a plan that would provide flat “global payments” to health provider networks that would act as incentives for them to keep their patients well. The hope is that the system will replace the current fee-for-service model that tends to increase medical costs because it reimburses [...]
Check out this video from TED. Genome sequencing continues to get more powerful and less expensive, just as we predicted. The ramifications are profound.
Development of technology for the wireless monitoring of vital signs and other physiological data continues to be a strong trend. The Universidad Carlos III de Madrid reports that scientists there have created an “intelligent” t-shirt that monitors temperature, heart rate, activity level and body position (standing, sitting, reclining). The shirt also embodies a localized GPS, [...]
When people have confidence in your products, you will have loyal, repeat customers. That’s an easy sale. If you are not using design to brand your entire product line, you are missing the opportunity to leverage your customers’ trust. Because technical function is so important in medical device design, it’s understandable that the majority of [...]
The Dutch Institute for Applied Science has developed a system for measuring body motion, heart rate and respiration using RADAR technology (watch the video posted at Quantified Self). This means that vital signs can be measured automatically via completely non-invasive means. The development team believes they can bring the system to market within a year. [...]
There is a new entrant in the personal health monitoring space. NewYu will be releasing a device in September that will help users track their exercise and calories burned. NewYu claims that it’s device can sense and distinguish between different types of movement, so it can tell if you are running, walking, using an eliptical [...]
Scientists at the University of Illinois have developed an ultrathin membrane inside of which they can embed electronic sensors. The membrane can conform and move along with the skin. Though the technology is not yet commercially viable, it points to where sensor and medical device design is headed: ever smaller. If electronics can be embedded [...]
I wrote previously about a technology being developed at MIT that uses infra-red light to detect blood glucose. Now, Northeastern University is working on a technology that binds nanoparticles to a target chemical when injected into the skin. They can then use LED light and an iPhone to read the nanoparticles when they fluoresce. The [...]
A couple of exciting recent developments will have a big impact on medical device design in the future: The technology surrounding brain-computer interface seems to be advancing quickly. Toyota has a project in which they are using a bike helmet equipped with EEG sensors to identify the brain signals associated with a bycicle rider thinking [...]
I wrote awhile back about the imperative of implementing Electronic Medical Records (EMR’s) on a widespread basis. The data such a system would provide would be invaluable in analyzing many factors that influence health and disease, and would reveal relationships that would be impossible to see otherwise. Initial efforts at such analysis and visualization are being [...]
Medical imaging will have advanced immensely. We will be able to isolate and visualize physiological functioning in real time. Blood flow, gastrointestinal processes, even synaptic firing in the brain will all be able to be seen, analyzed and evaluated. Genetic analysis will allow people to focus preventative care on their individual aspects of greatest risk. [...]
One of the most important things that doctors, nurses, clinicians and consumers look for in medical devices is ease-of-use. In fact, in a study just released by IBM’s Institute for Business Value, 96% of respondents said that ease-of-use was the top factor in selecting one device over another. Ease-of-use will become even more important as [...]
This week, Google announced that it was shutting down its Google Health service. Does this bode ill for the development and adoption of a universal Electronic Medical Records system? Not at all. It just means that Google didn’t get enough participation in the service to allow them to make money from ad revenue. There is [...]
P4 Medicine – Predictive, Preventative, Personalized, Participatory – is where healthcare is headed. In the near term, as the bulk of the population ages, there will still be a large portion of the industry devoted to treating disease. But more and more of medicine’s focus will be on neutralizing problems before they occur. Advances in [...]
I have been emphasizing how, in order to truly control health costs, it will be imperative to figure out how to get people to live healthy lifestyles in order to avoid disease and, in so doing, obviate the need for expensive interventionary care. In my reading about future trends in medicine, it’s become apparent that [...]
Last year I wrote several posts about the personal informatics trend – using technology to track our habits and various aspects of our physiology. At that time I noted how coupling devices with sensors to automatically collect data would help to bring personal informatics into the mainstream. Now we are seeing Ford Motor Company investigating [...]
Over at Medicalmegatrends.blogspot.com, Dr. Stephen Schimpff has some cogent thoughts about the root causes of rising healthcare costs in the United States. Doctor Schimpff reinforces my own view: that healthcare costs won’t be brought under control until we incentivize staying healthy. Read his post here: http://bit.ly/khNUYp.
Last week I wrote about the highlights from the FutureMed conference. Looking through the list, four overall trends emerge: Information technology for health. Personalized medicine. Control over biology. Targeted therapy. What do these trends mean for medical device design? First, medical devices that have any interaction with patients will need to be able to collect [...]
The FutureMed conference was recently held outside of San Francisco. MedGadget has a more detailed synopsis, but here are the bullet points regarding the incredible technologies that will transform medicine in the not-to-distant future: Information technology will be playing an increasingly improtant role in medicine. Being [...]
InTouch Health is a company that has developed a number of devices and services that enable physicians to interact remotely with hospital patients for consultation and active monitoring. Their latest product is a the RP-Xpress, “a lightweight, rugged, portable device that brings the physician to the point of care”. This is the kind of technology [...]
Medicaldevicestoday.com sights a study by Parks Associates that predicts that mobile health applications will soon be generating $5.5 billion in revenues by 2015. Of that amount, they say that 16% will be wellness/fitness related and 46% will be for chronic care monitoring and sevices. I hope the stats in their prediction are reversed. Only by [...]
Embrace them. Often times in creative endeavors, things go wrong. You play an unintended note. You draw an off-perspective line. But the accident gives you a new idea, or a different way of looking at the problem. Accidents can get you to places you never would have gotten to deliberately. They can often lead to [...]
Advancements in imaging technologies combined with the ability of computers to filter and enhance raw image data is creating a revolution in medical imaging. We are beginning to see techniques that provide realistic views of physical systems, organs and even cellular processes. Imagine being able to isolate a portion of a patient’s vascular system, see [...]
With the increase in smart phone computing power, specialized applications for health and the drive to lower health care cost, patients will be taking a more active role in monitoring and maintaining their own health. They will also be taking a more important role in treatments. What this means for medical device designers is that [...]
I was going back through some of my old papers and came across a piece from Newsweek written by Po Bronson and Ashley Merryman. Their article investigated what various researchers have found about creativity. It’s worth sharing the highlights: Brainstroming is not the best way for teams to come up with creative ideas. The same [...]
Most of us agree that the continuing growth in the cost of health care must be brought under control. In our efforts to contain those costs, we will see the biggest savings if we can get people to live healthy lifestyles, preventing the need for interventionary care in the first place. Although it is receiving [...]
To a writer, the most terrifying thing is a blank page. What to say? Where to begin? What if I can’t think of anything to say? What if my creativity is gone? Failure. The blank page can be paralyzing. One technique that writers use to get past their fear is to simply engage in the [...]
Corporations and managers love systems. They like things to be done the same way each time, in a step-by-step manner. Nothing stifles creativity quicker. There is no system for being creative. Hoping to develop medical device innovation by instituting a system is a fool’s errand. Leave the systems to the six-sigma folks. Your job is [...]
A body at rest stays at rest. A body in motion stays in motion. If only things were that simple. What we observe in the physical world is that everything is in a constant state of oscillation. You’re happy, you’re sad. You’re angry, you’re glad. The heart beats. Developing medical device innovation requires a similar movement [...]
Have you ever been in a meeting where creativity gets shut down because of something that happens in the group dynamic? Of course you have. Failing to effectively manage what happens in medical product development team group interactions is one of the biggest reasons why companies fail to innovate. Few companies are even aware of [...]
Last week I told you that you can’t innovate because your leaders are afraid. But it’s not all their fault. There’s another reason you can’t innovate, and its source is at the top of the organization. That’s right, I’m talking to you, Mr. CEO. You want your managers to foster innovation, but you yourself are [...]
You can't innovate because your leaders are afraid. They’re afraid of doing things differently. They’re afraid of the consequences of failure. So they play it safe. They don’t risk much. They talk about innovation, but it’s only lip service. You know how to generate remarkable new ideas. You know how to create. But when your [...]
We attended the Medtech 2010 conference in Durham this week. The most important thing we took away was the opinion, expressed by several presenters, that the overall value a medical device delivers is becoming a more important consideration than simply its cost. In other words, medical devices that deliver better health outcomes in relation to [...]
Medical Devices Today recently cited an article from In-Vivo that talks about “negative innovation”. Basically, the idea is that advances in clinical value need to take a back seat to cost savings. In other words, not doing more with less, but doing the same with less. What this says to us is that cost reduction is [...]
You’ve done a lot of research. You’ve developed some promising concepts. You’ve gathered the team together and now it’s time to evaluate and make some decisions. Amid the egos and agendas and politics, how do you make sure you’re choosing the ideas to move forward that will ultimately have the best chance of becoming a [...]
Last week we spoke about a new development in blood glucose sensing that uses infra-red light combined with a software algorithm that calibrates the signal. Using software to interpret, amplify and enhance instrument-acquired signals will become more common in imaging applications. Look to this kind of technology to have significant impact on future imaging devices [...]
Sticking your finger with a lancet will be a thing of the past. Non-invasive sensing will be a relatively near-term reality. One technology being developed at MIT is Raman spectroscopy, which uses infra-red light as a measurement collector. Read more about it here: http://web.mit.edu/newsoffice/2010/glucose-monitor-0809.html Another technology being developed at the University of Washington utilizes nanoscale [...]
People don’t have jobs so they can’t spend. The rampant consumerism that fueled the industrial age economy is gone. The service economy didn’t stand up to its hype. The information age produced the dot-com bubble. Forget about the jobs of the future -- where will the jobs of the present come from? How will the [...]
What are the emerging trends in healthcare, and how can medical device designers prepare for them? Sustainability. There will be a drive to reduce waste in all areas of health care delivery. Reducing packaging and moving away from disposables and back to re-usables will become the mantra. Self-care. The high cost of conventional modes of [...]
Far too often we’re presented with medical device design projects that arrive with constraints already firmly established. “We must use our existing manufacturing process”. “Our competitor has that feature, so we have to include it in our design”. “The filling vendors don’t like to do it that way”. If you’re really serious about medical device innovation, you [...]
Starts with courage. Courage to challenge the status quo. Courage to question constraints. Courage to defy the system. Courage to fight the me-too mentality. Courage to think big.
As the demand for sustainability grows louder, medical device design will need to find ways to significantly reduce environmental impact. This is especially so for single-use devices. Of the factors that affect sustainability, the type of material used and the amount of energy required at various stages of manufacturing, transporting and disposal are certainly major. [...]
Medical device design is primarily focused on treating problems, not on preventing them. In the future, containing health care costs will increasingly rely on maintaining wellness rather than curing once a problem has arisen. Also increasingly, people will be involved in managing their own self-care. Rather than individual medical devices, they’ll need an integrated system [...]
We’ve written previously about personal informatics in health care, and have noted that sensing technology and automatic data capture need to get better before personal informatics can become mainstream. Here are some examples of the current state of sensing and automatic capture technology: Medtronic’s iPro2 system: This device consists of a [...]
One of the biggest challenges in applying personal informatics in the medical arena lies in the sensing technology needed. Non-invasiveness and automatic data capture are the keys here. Currently there are a few methods that do capture some data this way: electroencephalography, electromyography, galvanic skin response, pulse oximetry, bioacoustic sensors. The Bodymedia Fit device http://www.bodymedia.com/ [...]
We’ve noticed a trend that has many implications for medical device designers and that bears watching: the increasing prevalence of “personal informatics”. This is a fairly new phenomenon, and one that will grow substantially in coming years. What is it exactly, and where is it headed? Personal informatics has a number of different names: “health [...]
One of the major trends in health care is that care once provided in the hospital or clinic is increasingly being provided at home by care givers or by the patients themselves. This trend gives rise to a number of issues that affect medical device design: Because users of medical devices in the home will [...]
Among the implications for medical device designers: Everyone will be able to have their genome sequenced. This will be a boon to laboratory instrument designers as the market for sequencers grows. Preventive medicine will become personalized. This could create a market for devices that do early screening for specific diseases. Specialization will occur with regard [...]
A few years ago, we conducted an extensive user research study in the U.S. and Europe surrounding a medical device design that addressed a less painful way of administering daily injections. In the States, Britain, Italy and France, every respondent was thrilled with the idea of less discomfort. The Germans, on the other hand, had [...]
People are wary of things they aren’t familiar with. You need to keep this at top of mind when interpreting what users tell you. Most can’t articulate what they want in a design. They only know that this thing is new and it’s not like what they’ve used before. In medical device design, you won’t [...]
To provide quality health care, one of a physician’s greatest concerns is that their patients comply with the physician’s prescribed treatment regimen. An accurate diagnosis and proper treatment course will have limited benefits if the patient fails to comply with the regimen. In treatment regimens where a device is needed to deliver the prescribed drug, [...]
Want to kill an idea? Put it before a committee. New ideas need a champion -- Someone who is vested in a successful outcome. Don’t expect casual players to push to the edges. It takes strength and decisiveness to drive a medical device design project beyond the ok and into the great. This is not [...]
Hospital rooms, medical clinics and operating suites present unique medical device design challenges. For example, the operating suite is often filled with numerous monitors and electronic instruments. Each could be vying for attention at the same time. Designing medical devices to provide effective alarm feedback in such an environment is problematic due to the visual and auditory [...]
Injection molders in the medical device industry are experienced in achieving thin walls, tight tolerances and very small part features. In those respects, medical device design has fewer constraints than do other industries where walls are typically thicker and features larger for structural integrity. Generally, we do everything possible to eliminate undercuts and other problematic [...]
In the medical device industry, designers often deal with decision makers who are medical doctors or scientists trained in specialized fields. In order to communicate effectively with them, medical device designers need to quickly get up to speed with the scientific terms and jargon that medical and scientific people use in their daily interactions with [...]
Many young medical device companies believe that their product will succeed in the market simply because their technology is stunning. When undertaking a medical device design project, why should such a company invest in industrial design? Because to not do so is bad strategy. Sure, revolutionary technology might be enough to get you established. But [...]
In most industries, you can get away with testing early prototypes using parts fabricated from various rapid prototyping technologies. In medical device design, performance issues are often so critical and part features so small that early testing must be done using parts fabricated from the actual resin that will be used in the finished device. [...]
It’s always a good idea to use multidisciplinary teams in a product development project. In medical device design, the interaction between the design and engineering functions requires an even closer collaboration than usual. This is because design changes are often immediate and far-reaching. That is, an engineering change can have a significant impact on industrial [...]
In all markets, products that have patentable features enjoy advantage over competitors. So why is intellectual property more important in the medical device design field? Mostly because product development costs are often so substantial that medical devices require a longer time period over which their development costs can be recovered. Patent protection provides this longer [...]
In other markets, part features that aid efficient manufacturing/assembly normally don’t need to be considered until the detailed engineering phase of the design process. In medical device design, however, part holding and assembly features can have a big impact on device design. For example, the ability of a particular design to accommodate sterile assembly and [...]
The requirement for sterility is unique to the medical market. Some medical devices require that sterility be maintained throughout the assembly and packaging cycles. Other medical products need only be sterilized in batches after they are packaged. Reusable hospital and surgical instruments must be able to be sterilized repeatedly. Designing with sterility requirements in mind [...]
The other half is won by a convincing argument. We’ve all been through the experience of having a client insist on changes to a design that will make it, let’s say, less than optimal. I think most medical device designers don’t give enough thought to the “whys” of their designs. They know what works intuitively. [...]
The Food and Drug Administration regulates most products that are used in the medical market in the U.S. Other industries are subject to strict rules as well, but I’m not aware of any that require as much control over the design process itself, as does the FDA. Thankfully the government doesn’t tell us how to [...]
In medical device design, what happens at the tiny scale of molecules can have a direct impact on what device designers do. In addition to biocompatibility issues, medical device designers need to be concerned with chemical reactions that could occur between say, drug molecules and device materials or between drug molecules and the outside environment. [...]
Some things just don’t get along with each other. That materials used in implantable medical devices must be compatible with the body is obvious. But there are unique material considerations in other areas of medical device design as well. The materials used in drug delivery devices, for example, must be compatible with the chemicals and [...]
If your laptop fails, little harm is done aside from some down time and the aggravation of having to have it replaced (ok, maybe more than a little aggravation!). If the interface on your digital camera is confusing, it’s annoying but you’ll figure out a way to get by. On the other hand, if your [...]
With health care reform so much in the news these days, cost containment is a big concern. Complying with the government’s regulations surrounding medical devices undoubtedly adds substantial cost to their development. How significant are those costs, though, in the overall scheme of caring for people’s health? Just about a year ago, former Congressional Budget [...]
Industrial designers are trained in methods that allow them to design for many different industries. However, in the same way that medical specialists require additional training above their basic knowledge, medical device designers also need a specialized knowledge set. Some of the ways in which medical device design differs from design for other markets: The [...]
