Abstract

An implantable prosthesis for repairing or reinforcing a tissue or muscle wall defect including a first composite structure including at least one layer of a non-absorbable material, wherein the first composite structure has a central portion sized and shaped to cover at least a portion of the tissue or muscle wall defect, and has an outer periphery. The prosthesis further includes a second structure having a reinforced central region and an outer peripheral edge, a reinforcing element positioned between the first and second structures, and having an outer periphery and a stiffness greater than that of the first and second structures, and at least one pulling element coupled to the reinforced central region of the second structure. The second structure is coupled to the first structure substantially only at their respective peripheries.

20. The prosthesis according to claim 19 having a substantially circular overall shape.

21. The prosthesis according to claim 19, wherein the reinforcing element has a three-dimensional shape.

22. The prosthesis according to claim 21, wherein the reinforcing element has an outer circumferential ring lying in a first horizontal plane and an inner circumferential ring lying in a second horizontal plane spaced apart from the first horizontal plane, and a plurality of spoke element extending between the inner and outer circumferential rings.

23. The prosthesis according to claim 19, wherein the first composite structure further comprises first and second absorbable film layers positioned adjacent top and bottom sides of the non-absorbable layer.

24. The prosthesis according to claim 23, wherein the non-absorbable layer is a mesh layer.

25. The prosthesis according to claim 24, wherein the first composite structure further includes an absorbable layer positioned adjacent a bottom side of the first film layer.

26. The prosthesis according to claim 19, wherein the central region of the second structure is reinforced by a ring element located therein.

27. The prosthesis according to claim 19, wherein the second composite structure is comprised of absorbable materials.

28. An implantable prosthesis for repairing or reinforcing a tissue or muscle wall defect, comprising:

a first substantially flat, flexible composite structure including at least one layer of non-absorbable material, the first composite structure having a central portion sized and shaped to cover at least a portion of the tissue or muscle wall defect and having an outer periphery;

a second substantially flat, flexible, structure having an outer periphery substantially similar to the outer periphery of the first structure, and having a reinforced central region;

a three-dimensional reinforcing element positioned between the first and second structures and having an outer periphery substantially similar to the outer periphery of the first and second structures; and

at least one pulling element coupled to the central region of the second structure;

wherein the first composite structure and the second structure are coupled to one another substantially only around their respective outer peripheries.

29. The prosthesis according to claim 28, wherein the reinforcement element further comprises an outer circumferential ring in a first horizontal plane, an inner circumferential ring in a second horizontal plane, and a plurality of spoke elements extending therebetween.

30. The prosthesis according to claim 28, wherein the at least one pulling element is a separate element coupled directly to the reinforced central region of the second structure.

31. The prosthesis according to claim 28, wherein the at least one pulling element is integrally formed with the first composite structure.

32. The prosthesis according to claim 28, wherein the non-absorbable layer of the first laminate structure is a mesh, and wherein the first structure further comprises first and second absorbable film layers positioned adjacent the top and bottom sides of the mesh.

33. The prosthesis according to claim 32, wherein the mesh is comprised of polypropylene and the first and second film layers are comprised of polydioxanone.
