The medical device is provided by a method that comprises: (a) attaching at least one reactive species to a medical device surface, which reactive species leads to chain growth polymerization in the presence of monomer; (b) contacting the reactive species with at least one monomer species, thereby forming a polymer coating on the surface of the medical device; and (c) providing at least one therapeutic agent within the polymer coating. The therapeutic agent may be incorporated during formation of the polymer coating or after formation of the polymer coating. The at least one reactive species can comprise, for example, a free radical species, a carbanion species. a carbocation species, a Ziegler-Natta polymerization complex, a metallocene complex, and/or an atom transfer radical polymerization initiator. Alternatively, the medical device is provided by a process comprising: (a) immobilizing least one polymerization catalyst at a medical device surface, which polymerization catalyst leads to polymerization in the presence of monomer; (b) contacting the medical device surface with at least one monomer species, thereby forming a polymer coating at the surface of the medical device; and (c) providing at least one therapeutic agent within the polymer coating.

    摘要: Implantable or insertable medical devices are described. The medical devices comprise (a) a therapeutic agent and (b) a polymeric release region that controls the release of the therapeutic agent upon administration to a patient. The polymer release region comprises a graft copolymer, which further comprises a main chain and a plurality of side chains. One of (a) the main chain and (b) the side chains corresponds to a rubbery phase within the release region at ambient temperatures, while the other corresponds to a hard phase within the release layer at ambient temperatures. Typically, the graft copolymer will comprise one glass transition temperature below ambient temperature and another second glass transition temperature above ambient temperature. Also described are methods for forming the above graft copolymers, methods for administering a therapeutic agent to a patient using the above implantable or insertable medical devices, as well as methods for making the above devices.
