Abstract
This invention is generally related to coatings for implantable medical devices, such as drug delivery vascular stents. The coating includes a drug reservoir layer above the outer surface of the device body, the drug reservoir layer with a peptide or protein, a hydrophobic drug, and a polymer with a weight average molecular weight between about 10,000 to about 150,000 Daltons. A preferred polymer is a poly(ester amide) polymer.
