COATINGS FOR IMPLANTABLE DEVICES INCLUDING BIOLOGICALLY ERODABLE POLYESTERS AND METHODS FOR FABRICATING THE SAME

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.
