Abstract
Abstract A composite structure is disclosed having two or more biocompatible polymers. At least one of the polymers is nonabsorbable. The nonabsorbable polymer is extruded into a fiber. The fiber can be fabricated into a textile structure, for example a woven mesh. The nonabsorbable mesh is then encapsulated with at least one bioabsorbable polymer. The composite structure is useful for repairing anatomical defects, for example in a mammalian abdominal wall.
