Polyethylene oxide and silicone copolymers and their usage on medical devices

摘要

An implantable medical device includes a device body at least partially formed of a polymeric material including a base polymer and a block copolymer. The block copolymer includes at least one polyethylene oxide (PEO) segment and at least one silicone (SI) segment, wherein the weight average molecular weight of the block copolymer is in the range of about 400 to about 50,000.
