Abstract:
According to an aspect of the present invention, a medical device is provided which comprises a metallic substrate and polymeric region disposed over and in contact with the metallic substrate. The polymeric region comprises (a) a block copolymer that comprises (i) a hard polymer block that comprises a high Tg monomer and (ii) a soft polymer block that comprises a low Tg monomer, (b) an adhesion promoting copolymer that comprises (i) a first monomer that covalently or non-covalently bonds with the metallic substrate and (ii) a second monomer that is compatible with the low Tg monomer and/or the high Tg monomer and (c) a therapeutic agent. The polymeric region may further comprise an optional polymer that is used to tailor the release rate of the therapeutic agent.
