RADIATION STERILIZED MEDICAL DEVICES COMPRISING RADIATION SENSITIVE POLYMERS

摘要

A medical device, for instance a device inserted into the body such as catheter or a balloon, at least a portion of which is made of a thermoplastic polymeric material. The thermoplastic polymeric material comprises a blend or laminate of an aromatic protectant polymer and a radiation sensitive polymer, and/or the polymeric material includes a stabilizer against radiation oxidative degradation. The device is sterilized by exposure to high energy radiation.
