Abstract

An areal implant has a long-term-stable, mesh-like basic structure which has pores of a size in the range from 1.5 mm to 8 mm and is provided, at least in a part area, on both sides with a synthetic, resorbable polymer film. The two polymer films are glued or welded together in pores of the basic structure.

Claims

1. An implant comprising mesh having pores over more than 90% of the total area where the pores range from 1.5 mm to 8 mm, and synthetic, resorbable polymer film on to each side of the mesh, where the two polymer films are glued or welded in at least a portion of the pores of the mesh.

2. The implant according to claim 1, where the mesh is made from at least one material selected from the group consisting of:

polypropylene, mixtures of polyvinylidene fluoride, copolymers of vinylidene fluoride and hexafluoropropene, and resorbable polymers.

3. The implant according to claim 1, where the polymer film is made from at least one of material selected from the group consisting of:

poly-p-dioxanone, copolymers of glycolide and lactide, mixtures of poly-p-dioxanone and polyethylene glycol, mixtures with polyethylene glycol, and copolymers of the aforementioned substances.

4. The implant according to claim 1, where the polymer films have a thickness in the range from 10 μ

m to 300 μ
