Abstract

The present invention relates to a prosthesis (200) comprising: one mesh (1) delimited by a peripheral exterior edge (1a), a frame (2) fastened to said mesh and adopting the shape of said peripheral exterior edge of the mesh, said frame being set back from said peripheral exterior edge and being provided with two hinge points (3a, 3b), the line passing through said two hinge points also passing through the centre (1b) of the mesh and thus forming a line M for folding the mesh in two, characterized in that said prosthesis further comprises at least two anchor pieces (5) made of suturable material and located on a single face of the mesh (1) on either side of said folding line, each piece having a fixed part (5a) linked to said mesh and a free part (5b), said free part being linked to at least one thread-shaped element (7).

Claims

1. A process for making a prosthesis comprising:

forming a cut on a textile to produce a cut textile, the cut in a shape of a cross including first and second branches,

placing the cut textile on a mesh, and

welding a frame to the cut textile and the mesh, the frame including two hinge points forming a folding line therebetween, wherein one of the first and second branches is positioned on the folding line and extends beyond the two hinge points of the frame.

2. The process of claim 1, wherein the textile has a square shape.

3. The process of claim 1, wherein the textile has a color which is different from the mesh.

4. The process of claim 1, wherein the textile is a knit having a warp direction and a weft direction.

5. The process of claim 1, wherein the mesh is a knit.

6. The process of claim 4, wherein the first branch is parallel to the weft direction and the second branch is parallel to the warp direction of the textile.

7. The process of claim 1, wherein the first and second branches are generally perpendicular to each other.

8. The process of claim 1, wherein a length of the second branch is smaller than a length of the first branch.

9. The process of claim 1, wherein a length of the second branch is smaller than a diameter of an inner diameter of the frame.

10. The process of claim 1, wherein a length of the first branch is larger than a diameter of an outer perimeter of the frame.

11. The process of claim 1, wherein the frame is generally circular.

12. The process of claim 1, wherein the frame is of serpentine shape forming undulations.

13. The process of claim 1, wherein said frame takes the form of a flat ribbon forming undulations substantially in a plane of the mesh.

14. The process of claim 1, further comprising cutting the cut textile and the mesh in excess beyond an outer peripheral border of the frame to produce the prosthesis.

15. The process of claim 1, wherein the two hinge points of the frame are diametrically opposed on the prosthesis.

16. The process of claim 1, wherein the two hinge points are on the frame and the folding line extends across a center of the prosthesis therebetween.

17. The process of claim 1, wherein the one of the first and second branches extends beyond the frame towards an outer edge of the prosthesis.

18. The process of claim 1, wherein the frame in combination with the first and second branches form four anchor pieces of the textile, wherein each anchor piece includes a fixed part linked to the mesh and a free part.

19. The process of claim 18, wherein the four anchor pieces are isosceles triangles.

20. The process of claim 18, further comprising linking at least one thread-shaped element to the free parts of at least two anchor pieces.

21. The process of claim 20, wherein the at least two anchor pieces are located on the same side of the folding line.

22. The process of claim 20, wherein the thread-shaped element is selected from threads, flexible tubes and combinations thereof.

23. The process of claim 18, further comprising applying a non-adherent coating to a face of the mesh opposite that including said anchor pieces.

24. A process for making a disc-shaped prosthesis comprising:

forming a cut on a square textile to produce a cut square textile, the cut in a shape of a cross including first and second branches,

placing the cut square textile on a mesh, and

welding a circular frame to the cut square textile and the mesh, the circular frame including two hinge points forming a folding line therebetween, wherein one of the first and second branches is positioned on the folding line and extends beyond the two hinge points of the frame, and

cutting the cut square textile and the mesh in excess beyond an outer peripheral border of the circular frame to produce a disc-shaped prosthesis.
