<p>Coatings are provided in which surfaces may be activated by covalently bonding a silane derivative (A) to the metal surface, covalently bonding a lactone polymer (B) to the silane derivative by in situ ring opening polymerization, and depositing at least one layer of a polyester (C) 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.</p> |
