Abstract:
1. A medical article comprising an implantable substrate having a coating, the coating comprising a first biologically erodable polymer having a glass transition temperature below about −50° C. and a biologically erodable polymeric additive mixed with the first polymer, wherein: the polymeric additive has a degree of crystallinity greater than that of the first polymer and has a glass transition temperature of about −50° C. or greater; the first polymer is selected from poly(esters), poly(caprolactone), poly(4-hydroxybutyrate), poly(3-hydroxyvalerate), poly(3-hydroxybutyrate-co-3-hydroxyvalerate), and mixtures thereof; and the polymeric additive is selected from poly(L-lactide), poly(L-lactide-co-D,L-lactide), poly(glycolide), poly(glycolide-co-L-lactide), poly(caprolactone-co-L-lactide), poly(caprolactone-co-D,L-lactide), copolymers of trimethylene carbonate, and mixtures thereof.
