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 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. 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: 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 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.
