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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
62 words
A surgical composite structure for mammalian tissue comprising: a) a nonabsorable woven component prepared from a plurality of fibers, the fibers comprising a polybutester, and b) a film consisting essentially of bioabsorbable component laminated to the nonabsorbable woven component, the bioabsorbable component comprising a random compolymer prepared from at least two monomers selected from the group consisting of lactides, carbonates and lactones.
Claim 2
Dependent Claim
62 words
A surgical composite structure for mammalian tissue comprising: a) a nonabsorable woven component prepared from a plurality of fibers, the fibers comprising a polybutester, and b) a film consisting essentially of bioabsorbable component laminated to the nonabsorbable woven component, the bioabsorbable component comprising a random compolymer prepared from at least two monomers selected from the group consisting of lactides, carbonates and lactones.
Claim 3
Dependent Claim
20 words
The composite structure of claim 1 wherein the random copolymer is prepared from at least the monomers glycolide and 1,3-dioxan-2-one.
Claim 4
Dependent Claim
62 words
A surgical composite structure for mammalian tissue comprising: a) a nonabsorbable reinforcing component prepared from a plurality of fibers, at least one of the fibers manufactured from a polymer selected from the group consisting of a polybutester and blends of the same, and b) a film consisting essentially of a bioabsorbable component comprising a polymer prepared from the monomers glycolide and 1,3-dioxan-2-one.
Claim 5
Dependent Claim
62 words
A surgical composite structure for mammalian tissue comprising: a) a nonabsorbable reinforcing component prepared from a plurality of fibers, at least one of the fibers manufactured from a polymer selected from the group consisting of a polybutester and blends of the same, and b) a film consisting essentially of a bioabsorbable component comprising a polymer prepared from the monomers glycolide and 1,3-dioxan-2-one.
