    摘要: A medical article comprising an implantable substrate having a coating is disclosed, the coating comprising a biologically erodable polymer having the glass transition temperature below about −50° C. The biologically erodable polymer can be blended with a polymeric additive which either has the glass transition temperature of about −50° C. or higher, or a degree of crystallinity greater than that of the first polymer.

    摘要: Various embodiments of methods and devices for coating stents are described herein. Among these embodiments are methods of manufacturing an implantable medical device by purifying a polymer with a fluid capable of swelling the polymer, and subsequently coating a device with the purified polymer or fabricating a device from the purified polymer. A preferred polymer is poly(vinylidene fluoride-co-hexafluoropropylene).
