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 web of continuous filaments which are made of at least one semi-crystalline polymeric component covalently bonded as a linear block copolymer with or blended with one or more semi-crystalline or amorphous polymeric components. The filaments are intermingled together to form a porous web of filaments, the filaments having multiple contact points with each other within the web. The filaments are bonded at the contact points without requisite for added adhesive binders, adjuncts or post extrusion melt processing. The web may be bioresorbable. The web may also be provided in forms with relatively high cohesive shear strength. The polymeric components of the filaments exist, at least temporarily, in a homogenous substantially phase miscible uncrystallized state. If preserved in the homogenous substantially phase miscible uncrystallized state, the object can then be manipulated into a distinct desirable molded shape and then subsequently set or crystallized to retain the desired form particularly suitable for a specific use or application.
摘要翻译: 由至少一种半结晶聚合物组分制成的连续长丝纤维网,其共价键合为线性嵌段共聚物或与一种或多种半结晶或无定形聚合物组分共混。 将细丝混合在一起以形成多孔纤维网,该丝在网内彼此具有多个接触点。 长丝在接触点处粘合,无需添加粘合剂粘合剂,助剂或后挤出熔融加工。 网可以是生物可再吸收的。 纤维网也可以具有相对高的内聚剪切强度的形式提供。 长丝的聚合物组分至少暂时存在于均匀的基本相混合的未结晶状态。 如果保持在均匀的基本相混合的未结晶状态,则可以将物体操作成不同的期望的模制形状,然后随后设定或结晶以保持特别适用于特定用途或应用的所需形状。
