Forty years of medical product design and development experience

Founded in 1970 as Designs for Medicine, the company's first product was the Stand-Up Wheelchair. Since then, the medical product design team at Bresslergroup has designed and engineered hundreds of medical products ranging from surgical instruments, drug delivery devices, home health and rehabilitation devices, to complex medical systems.

Leaders of our medical product design and development staff include:

  • Dave Schiff, Director of Research and Development, has 26 years of mechanical innovation in medical product design and development under his belt. He has led product development on projects including arthroscopic instruments, bioabsorbable tacking device, needleless injectors, TA and GIA surgical staplers, automated blood glucose monitor, Lasik® microkeratome, inhalers, and other platforms for medical drug delivery. Dave makes sure Bresslergroup is using the latest tools for technical innovation, and he helps oversee Bresslergroup's engineering discipline.
  • Keith S. Karn, PhD, Director of User Research, provides expertise and training in contextual inquiry observation, human factors, and usability for interface and medical product design. Keith is an expert in usability evaluation methods that drive design innovation. He has extensive experience leading formative and validation user studies to meet the requirements of the FDA and European governing bodies related to the application of human factors and usability engineering.  During his 30-plus year career in human factors engineering and product development, he has led a wide variety of initiatives in the healthcare industry, including a diverse portfolio of medical devices and the redesign of healthcare information technology systems. 

Bresslergroup has developed medical devices for organizations across the spectrum of medical products, including Becton Dickinson, Covidien, Infrascan, Johnson & Johnson, Siemens, Vidar, and Zimmer. Our engagements range from targeted research, design, or engineering projects to comprehensive definition, specification, and manufacturing support, including offshore quality assurance. In addition to the core disciplines of research, design, and engineering, we are experienced and capable in project and vendor management for medical device development.

Pictured on this page is a portable medical oxygen concentrator developed for Air Products and Devilbis. Air Products developed the proof of concept model for a lightweight, portable oxygen concentrator which would deliver up to 5 liter/minute high purity oxygen. Bresslergroup joined their medical product design and development team to help design, engineer and commercialize the new medical product.

When we began the project, the Air Products R&D had a benchtop proof of concept device which proved they could generate the right amount of high purity oxygen. They turned to us to turn the concept into a real product that consumers could use and medical experts could specify with confidence.

Initial research included significant competitive and user study to define the system feature set. Human factors requirements for weight, size, noise and other user centric features drove the medical product design team toward the smallest possible product size. Mechanical and electronics were developed in parallel to ensure efficiency of product design. The team also investigated appropriate aesthetics to identify styling options for the device which wanted to be discrete while fostering pride in new found mobility.

Meeting low weight and noise targets for this medical product design drove significant engineering effort to optimize the package. Medical customers often sleep while using the product and don’t want to cart around a noisy unit. Interface elements and electronic controls were also developed for ease of use and failsafe performance.

Ultimately, the team developed the device shown on this page. The unit met performance requirements, delivering the most high purity oxygen per pound on the market. The new medical product was also designed to be easy to understand and use by medical customers, including a non-intimidating look and simplified user interface elements. The new unit also led to additional IP protection for Air Products and helped them develop new business partnerships for distribution of consumer medical devices.
