A61B 17/06

Abstract:

Novel surgical sutures and novel medical devices made from novel semi-crystalline, glycolide-rich A-B-A triblock copolymers of glycolide and lactide, wherein said B-segment is a fully amorphous random copolymer of glycolide and lactide, for long term medical applications are disclosed. The novel polymer compositions are useful for long term absorbable surgical sutures, meshes and other medical devices, especially for patients with compromised healing. The novel sutures have improved properties and improved breaking strength retention, while still substantially absorbing within about a 120-day period post-implantation.

US Classification:

525411

Abstract:

Novel absorbable polymeric blends are disclosed. The blends have a first absorbable polymer type that is a polylactide polymer or a copolymer of lactide and glycolide and a second absorbable polymer type that is poly(p-dioxanone), wherein the first absorbable polymer type or the second absorbable polymer type or the first absorbable polymer type and the second absorbable polymer type additionally comprise a first polymeric component and a second polymeric component. The first polymeric component has a higher weight average molecular weight than the second polymeric component and at least one of said components is at least partially end-capped by a carboxylic acid. The novel polymeric blends are useful for manufacturing medical devices having dimensional stability, having engineered degradation and breaking strength retention in vivo. Also disclosed are novel absorbable medical devices made from these novel polymer blends, as well as novel methods of manufacture.
