    摘要: Disclosed are vascular grafts including an expanded copolymer of tetrafluoroethylene (TFE) and perfluoropropylene vinyl ether (PPVE). In certain embodiments, the copolymer includes between about 0.01% and about 1.5% PPVE. Vascular grafts exhibit superior performance properties, e.g., radial strength, and suture strength, and manufacturing properties, e.g., sinter time. Methods of forming vascular grafts from the copolymer also are described.

    摘要: A barrier device is formed of a barrier component that can exhibit anti-inflammatory properties, non-inflammatory properties, and/or adhesion-limiting properties, as well as generate a modulated healing effect on injured tissue. The barrier component can be a non-polymeric cross-linked gel derived at least in part from a fatty acid compound, and may include a therapeutic agent. The barrier device can have anchoring locations to provide an area on the barrier device to interface with an anchoring mechanism. The anchoring locations can include openings and/or anchor elements. The barrier device can also include truss structures that provide additional strength to the barrier component. The barrier device is implantable in a patient for short term or long term applications, and can include controlled release of the therapeutic agent.
