Surgical adhesion barriers and methods of using such surgical adhesion barriers are provided. Surgical adhesion barriers according to the present invention have at least one layer of a bioabsorbable material comprising copolymers and/or block copolymers derived from trimethylene carbonate. Alternatively, a multilayer surgical structure having one or more bioabsorbable layers superimposed on a non-absorbable layer is useful for minimizing or preventing formation of fibrous adhesions between a healing trauma site and adjacent surrounding tissue. Alternatively, a bioabsorbable non-woven fabric in adherent contact with at least one bioabsorbable layer of foam, film, mesh, web or woven fabric is also provided. One or more medicinal agents may be interposed between or disposed within any of the aforementioned layers.
本发明提供了手术粘附屏障和使用这种手术粘附屏障的方法。根据本发明,手术粘连屏障至少有一层生物可吸收材料,该材料由源自碳酸三亚甲酯的共聚物和/或嵌段共聚物组成。另外,具有一层或多层叠加在非吸收层上的生物可吸收层的多层手术结构可最大限度地减少或防止愈合创伤部位与邻近周围组织之间形成纤维粘连。另外,还可提供一种生物可吸收无纺布,该无纺布与至少一层泡沫、薄膜、网、网布或编织布生物可吸收层粘连接触。一种或多种药剂可夹在上述任何层之间或置于其中。
