摘要： Bioabsorbable self-expanding medical devices formed of an integral framework with a multiplicity of fenestrations are provided. The framework is continuous, non-filamentous, non-braided, and non-interlaced. The devices includes a non-blended hydrolysable co-polymeric material comprising an amorphous component with a glass transition temperature that is below ambient body temperature and a crystallizable component that possesses a crystalline melting point in excess of ambient body temperature. The devices radially expand from a compressed first diameter to an uncompressed second diameter equal to or greater than 1.5 times the first diameter within two minutes in an aqueous medium at 37° C. following release of a compressive force placed on the devices. Additionally, the medical device does not change axial length significantly as the radial dimensions of the devices are changed. Further, the medical devices may be constructed of different bioabsorbable polymers, polymer ratios, and/or different geometries and portions may bioabsorb at different rates.

摘要： A medical device provided with at least a partial surface coating of a thermoplastic copolymer of tetrafluoroethylene and perfluoroalkylvinylether that is free of cross-linking monomers and curing agents. The fluoropolymer coating is preferably an amorphous thermoplastic, is highly inert and biocompatible, has elastomeric characteristics that provide desirable mechanical properties such as good flexibility and durability. These characteristics allow the coating to be considered “functionally transparent” because it withstands mechanical deformations required for the assembly, deployment, expansion, and placement of medical devices, without any adverse effect on the mechanical and biological functionality of the coated device. Further, its inertness, derived from the perfluorocarbon structure, contributes to its functionally transparent nature. The coating can be provided with various liquid or solid additives, can be loaded with large quantities of additives including a wide range of therapeutic agents, and has excellent drug elution characteristics when elutable additives are used.
摘要翻译：一种医疗装置，其具有不含交联单体和固化剂的四氟乙烯和全氟烷基乙烯基醚的热塑性共聚物的至少部分表面涂层。含氟聚合物涂层优选为无定形热塑性塑料，具有高度惰性和生物相容性，具有提供所需机械性能（例如良好的柔韧性和耐久性）的弹性体特性。这些特性使得涂层被认为是“功能上透明的”，因为它可以承受医疗装置的组装，展开，膨胀和放置所需的机械变形，而不会对涂覆装置的机械和生物功能产生任何不利影响。此外，其衍生自全氟化碳结构的惰性有助于其功能上的透明性。该涂层可以提供各种液体或固体添加剂，可以加载大量的添加剂，包括广泛的治疗剂，并且当使用可洗脱添加剂时具有优异的药物洗脱特性。

The desirable mechanical characteristics are surprising given the absence of cross-linking monomers and curing agents that would otherwise render such materials inadequately biocompatible. The perfluoroalkylvinylether may be perfluoromethylvinylether, perfluoroethylvinylether or perfluoropropylvinylether.

摘要： A method of occluding includes imbibing a porous elongate element comprised of ePTFE with a calcium-containing solution. The method also includes delivering, via a delivery catheter, the calcium-imbibed porous elongate element to a target occlusion site. The method further includes administering, after the calcium-imbibed porous elongate element has been completely delivered to the target occlusion site and resides entirely within a volume defined by the target occlusion site, an alginate-containing solution to the target occlusion site.

摘要： A catheter provided with a guidewire catheter lumen having a thin covering that is easily punctured by a guidewire at virtually any desired point along the catheter length. The thin covering may be integral with the catheter shaft, or may be a separate component that covers only the portion of the catheter shaft immediately adjacent the outer portion of the guidewire lumen, or may be a thin tubular construct that surrounds the entire catheter shaft. The covering is preferably relatively translucent, allowing for good visualization of the location of the end of the guidewire to enable puncturing of the covering at the desired location along the length of the catheter shaft. The covering is also preferably tear resistant at puncture sites. The catheter shaft is preferably made of a material having a color that provides good visibility against an operating field, and more preferably is phosphorescent either entirely or in part. Materials suitable for the catheter shaft are polymeric materials well known in the art; the catheter shaft may optionally be provided with metallic stiffening components such as wires or hypotubes along all or part of the catheter length.

摘要： The present invention is an improved endovascular device particularly useful for use in transjugular intrahepatic portosystemic shunt (TIPS) procedures. The device employs a two-part stent-graft construction that provides a low permeability membrane to line the shunt and an uncovered stent portion designed to reside in the portal vein. The device provides numerous benefits over previous stents and stent-grafts used in TIPS procedures, including being more compact to deliver, being easier to accurately deploy, a controlled compacted surface with tucked apices, an improved stent winding pattern, and being more flexible in delivery and use.
