An important input to FEA is material characterization and limit information. In our laboratory we use a Bose 3230 test system for achieving test speeds up to 200Hz. Depending on the project, we may test complete devices, sub-components, coupon samples and/or simple material characterization samples. Many times, we will test more than one [...] For medical devices, rarely does “one size fit all”. The human body is extremely variable and patient populations, especially those with disease present a wide range of differences that the medical device design engineer must consider. Identifying the worst case size for a product family is an important part of the validation process for implantable [...] My first job out of graduate school and post-doctorate work was with the footwear company, NIKE. I was fortunate to hire into the heart of the most advanced footwear technology department in the world and I could not have had a more exciting job description. I began by learning how to design NIKE AIR cushioning [...] Nitinol is a unique metallic alloy that is ideally suited to use in medical devices. It has excellent biocompatibility and most of all it has the ability to undergo significant recoverable deformations. This allows devices made with Nitinol to be reduced to catheter dimensions and expanded at the implant site. Much work has been done to [...] |
