Abstract

Prosthesis (1) comprising one porous mesh (2) comprising a first face and a second face opposite the first face, the prosthesis (1) comprising: —one porous strengthening means (6) which strengthens the mesh (2) and is intended to cover at least part of one of said first and second faces of the mesh (2), —fastening means for fastening the strengthening means (3) to the mesh (2), in a position fastened to the mesh (2), the strengthening means (6) covers a peripheral part (7) of one of said first and second faces of the mesh.

Claims

1. A prosthesis for medical or surgical use comprising:

at least one porous mesh made of biocompatible material, the mesh comprising a first face, a second face opposite the first face, and a first set of barbs integral to and extending from the mesh and configured to attach the prosthesis to biological tissue, at least one strengthening means which strengthens the mesh and is intended to cover at least part of one of the first and second faces of the mesh, a second set of barbs integral to and extending from the strengthening means and configured to permit reversible fixation and renewed fixation of the strengthening means to the mesh, wherein the strengthening means is porous, pores of the mesh having dimensions larger than pores of the strengthening means, and, in a position fastened to the mesh, the strengthening means covers a peripheral part of one of the first and second faces of the mesh.

2. The prosthesis according to claim 1, wherein the strengthening means comprises a bioabsorbable material and the mesh comprises a partially bioabsorbable material.

3. The prosthesis according to claim 1, wherein the strengthening means comprises a partially bioabsorbable material and the mesh comprises a bioabsorbable material.

4. The prosthesis according to claim 1, wherein the strengthening means further covers a central part of one of the first and second faces of the mesh.

5. The prosthesis according to claim 1, wherein the first set of barbs are situated on one or both of the first and second faces of the mesh.

6. The prosthesis according to claim 1, wherein the strengthening means comprises at least one piece of a textile made of biocompatible material.

7. The prosthesis according to claim 6, wherein the textile comprises a color distinct from a color of the mesh.

8. The prosthesis according to claim 7, wherein the color of the textile and the color of the mesh generate a contrast of 50% to 100% according to the scale of contrast sensitivity defined for public buildings.

9. The prosthesis according to claim 7, wherein the color of the textile and the color of the mesh generate a contrast of 70% to 100% according to the scale of contrast sensitivity defined for public buildings.

10. The prosthesis according to claim 7, wherein combinations of the color of the textile and the color of the mesh are selected from the group consisting of beige/red, beige/blue, beige/green, beige/purple, beige/pink, beige/brown, beige/black, beige/grey, white/red, white/orange, white/pink, white/brown, white/black, white/grey, grey/yellow, grey/black, black/yellow, black/orange, black/green, black/purple, black/pink, brown/yellow, brown/orange, brown/pink, pink/red, pink/yellow, pink/blue, purple/yellow, green/yellow, green/orange, orange/red, orange/yellow, orange/blue, blue/yellow, and yellow/red.

11. A prosthesis for medical or surgical use comprising

at least one porous mesh made of biocompatible material, the mesh comprising a first face, a second face opposite the first face, and a first set of barbs for attaching the mesh to biological tissue, a first nonwoven textile made of a porous biocompatible material which strengthens the mesh and covers a peripheral part of at least one of the first and second faces of the mesh, the first nonwoven textile including a second set of barbs for fastening the first nonwoven textile to the peripheral part of the mesh, wherein pores of the mesh have dimensions larger than pores of the first nonwoven textile.
