A major concern with medical device design is the amount of friction created during contact on the body or other materials or parts that come in contact with each other. Precise friction measurement gives control to reduce friction which can cause inflammation or infection from wear debris. It can also be used to minimize insertion force, such as with stents, to maximize patient comfort. Quantifiable, reproducible and reliablefriction measurement is therefore crucial to control the machineability of medical devices.
