摘要： A coating composition for use in coating implantable medical devices to improve their ability to release bioactive agents in vivo. The coating composition is particularly adapted for use with devices that undergo significant flexion and/or expansion in the course of their delivery and/or use, such as stents and catheters. The composition includes the bioactive agent in combination with a mixture of a first polymer component such as poly(butyl methacrylate) and a second polymer component such as poly(ethylene-co-vinyl acetate).
