CLAIMS

What is claimed is:

A bioresorbable copolymer of the structure A-B-A, wherein end-segments A comprise polymerized lactide blocks and the middle segment B comprises a polymerized lactide-co-epsilon-caprolactone block, and wherein said middle segment B represents about 25 weight percent to about 60 weight percent of the copolymer.

DESCRIPTION

FIELD OF THE INVENTION

This invention relates to novel semi-crystalline, block copolymers of lactide and epsilon-caprolactone for long term absorbable medical applications, in particular, surgical sutures and hernia meshes. One use of the copolymers of the present invention is the fabrication of monofilament surgical sutures.
