摘要： The biodegradable mesh and film stent for use in blood vessels is formed of a sheet of a composite mesh material formed of biodegradable high strength polymer fibers bonded together with a second biodegradable adhesive polymer, and laminated on at least one side with a thin film of a third biodegradable polymer. The biodegradable mesh and film material is formed as a sheet and cut in a shape that can be used as a stent, such as a "belt-buckle" type shape, the ends of which can be joined in a contractible, expandable loop. In the method of making the biodegradable composite mesh and film stent, the composite mesh is preferably formed from a weave formed of high strength biodegradable polymeric fibers, and a plurality of low temperature melting biodegradable polymeric fibers. In an alternate embodiment, the high strength fibers are commingled with the low temperature melting fibers. In another alternate embodiment, the high strength fibers are coated with the low temperature melting polymer. The composite mesh is covered on at least one side by a laminating film, and is then cut into the shape of the stent.
摘要翻译：用于血管的可生物降解的网膜和薄膜支架由一片由可生物降解的高强度聚合物纤维形成的复合网格材料形成，该聚合物纤维与第二可生物降解的粘合剂聚合物结合在一起，并且在至少一侧上用薄膜第三种可生物降解的聚合物。可生物降解的网状物和薄膜材料形成为片材，并且被切割成能够用作支架的形状，例如“带扣”形状，其端部可以以可收缩的可扩张环接合。在制造可生物降解复合网和膜支架的方法中，复合网优选由由高强度可生物降解的聚合物纤维形成的织物和多个低温熔融的可生物降解的聚合物纤维形成。在替代实施例中，高强度纤维与低温熔融纤维混合。在另一个替代实施例中，高强度纤维被低温熔融聚合物涂覆。复合网在至少一侧用层压膜覆盖，然后切割成支架的形状。
