Abstract
Coatings are provided in which surfaces may be activated by covalently bonding a silane derivative to the metal surface, covalently bonding a lactone polymer to the silane derivative by in situ ring opening polymerization, and depositing at least one layer of a polyester on the bonded lactone. Biologically active agents may be deposited with the polyester layers. Such coated surfaces may be useful in medical devices, in particular stents.
