  • Publication number: 20070117925
    Abstract: In one aspect, the present invention provides implantable or insertable medical devices, which contain at least one polymeric region. The polymeric region contains at least one fluorocarbon-containing block copolymer, which, in turn, contains (a) at least one fluorocarbon-containing, low glass transition temperature (low Tg) copolymer chain and (b) at least one glass transition temperature (high Tg) polymer chain.

  • Publication number: 20060171985
    Abstract: The present invention relates to phase separated polymeric regions and to their use in conjunction with implantable or insertable medical devices. In some aspects of the invention, phase separated polymeric regions are provided that include (a) at least one biostable polymeric phase and (b) at least one biodisintegrable polymeric phase, which is of nanoscale dimensions and which undergoes biodisintegration such that the phase separated polymeric region becomes a nanoporous polymeric region in vivo. Other aspects of the invention are directed to methods of making implantable or insertable medical devices having at least one nanoporous polymeric region. These methods include (a) providing a phase separated polymeric region comprising a stable polymeric phase and a disintegrable polymeric phase of nanoscale dimensions, (b) selectively removing the disintegrable polymeric phase thereby producing the nanoporous polymeric region.

  • Publication number: 20060013849
    Abstract: The present invention relates generally to radiation-resistant medical devices which contain polymer regions for release of therapeutic agents. The present invention also relates to radiation-resistant block copolymer materials for use in connection with insertable or implantable medical devices. The radiation-sterilized medical device comprise (a) a release region and (b) at least one therapeutic agent and the release region comprises a radiation resistant copolymer that includes (i) a low Tg hydrocarbon polymer block and (ii) one or more high Tg polymer blocks.

  • Publication number: 20050025803
    Abstract: 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.
