Failure Mechanisms of Polymeric Medical Devices

Abstract

Medical devices manufactured today typically require a number of different components and materials. Commonly, mass-produced devices utilize biocompatible polymers for their external surfaces. In this article, we discuss common failure mechanisms of polymers and a number of contributing factors, related to both the use and manufacturing of these devices. Reprocessing and cleaning of reusable medical devices can also contribute to their failures when incompatible substances or techniques are used. Thorough postmarket reporting of any medical device failure can allow enhancements of the device to be made and will ultimately improve patient safety.
