Absorbable, segmented copolymers of aliphatic polyesters based on lactone monomers glycolide, and p-dioxanone are described. The segmented copolymers exhibit a broad range of properties, especially high strength and stiffness, and fast absorption rates and breaking strength retention (BSR) profiles, useful in a variety of medical devices. Most importantly, for suture applications where Vicryl TM -like polyglcolide-polylactide sutures with excellent tensile properties, but shorter BSR profiles than Vicryl TM are needed. The copolymers of the present invention have such properties, making them useful in plastic surgery where faster absorption times would lead to less tissue scarring. |
