Composite bioabsorbable materials and surgical articles made therefrom

摘要

Composite materials have a core portion formed from a biocompatible material and at least one shell portion of a biocompatible material joined to the core portion. In a preferred embodiment, the core portion is coextruded with the shell portion to form a composite filament or sheet. The composite materials may be used as sutures or formed into medical devices or surgical articles for implantation within a living organism.
