Abstract

The present disclosure relates to a prosthesis comprising:

• • one mesh delimited by a peripheral exterior edge, a frame 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, the line passing through said two hinge points also passing through the center of the mesh and thus forming a line for folding the mesh in two, characterized in that said prosthesis further comprises at least two anchor pieces made of suturable material and located on a single face of the mesh on either side of said folding line, each piece having a fixed part linked to said mesh and a free part, said free part being linked to at least one thread-shaped element.

Claims

1. A prosthesis comprising:

at least one flexible mesh delimited by a peripheral exterior edge,

at least one member for reinforcing said mesh, said reinforcing member taking the form of a frame fixed to said mesh and substantially adopting a shape of said peripheral exterior edge of the mesh, said frame being set back from said peripheral exterior edge and defining an inner perimeter, the frame being provided with two hinge points, a folding line passing through said two hinge points also passing through a center of the mesh for folding the mesh in two

wherein said prosthesis further comprises at least two anchor pieces located on a single face of the mesh on either side of said folding line, each anchor piece is a triangular textile having a fixed part linked to said mesh via a base of the triangular textile, the base located along the inner perimeter of the frame and a free part, said free part being linked to at least one thread-shaped element.

2. A prosthesis according to claim 1, wherein each anchor piece is linked to the mesh by its longest side, along a direction perpendicular to a segment linking the center of the mesh and a point of fixation of said piece in a plane of the mesh.

3. A prosthesis according to claim 1, wherein the at least one thread-shaped elements are selected from threads, flexible tubes and combinations thereof.

4. A prosthesis according to claim 3, wherein the thread-shaped elements are flexible tubes.

5. A prosthesis according to claim 4, wherein the tubes are flexible and semi-rigid.

6. A prosthesis according to claim 1, wherein the frame set back from the peripheral external edge is of serpentine shape forming undulations.

7. A prosthesis according to claim 6, wherein said frame takes the form of a flat ribbon forming undulations substantially in a plane of said mesh.

8. A prosthesis according to claim 1, wherein said reinforcing member is produced in bioresorbable material.

9. A prosthesis according to claim 1, wherein said mesh is disc-shaped, said frame being substantially in a form of a circular ring.

10. A prosthesis according to claim 9, wherein said at least two anchor pieces are fixed to diametrically opposed places of an inner perimeter of said ring, said two places being spaced by 90°

from each of said two hinge points.

11. A prosthesis according to claim 9, wherein the prosthesis comprises four said anchor pieces distributed substantially regularly along an inner perimeter of said ring so that two anchor pieces are located on one side of the folding line and the other two anchor pieces are located on the other side of said folding line.

12. A prosthesis according to claim 11, wherein a single thread-shaped element links together the free parts of two anchor pieces located on the same side of the folding line.

13. A prosthesis according to claim 11, wherein all four anchor pieces are under the form of isosceles triangles of textile, all four triangles showing identical elongation and tensile strength properties in a centripetal direction.

14. A prosthesis according to claim 1, wherein the anchor pieces have a color different than that of the mesh.

15. A prosthesis according to claim 1, wherein the thread-shaped elements have a color different than that of the mesh and than that of the anchor pieces.

16. A prosthesis according to claim 1, wherein the face of the mesh opposite that including said anchor pieces is covered by a non-adherent coating.

17. A prosthesis according to claim 1, wherein the at least two anchor pieces are separate individual pieces.

18. A prosthesis according to claim 1, wherein the at least one thread-shaped element comprises at least one thread linked to said free part of the at least two anchor pieces, wherein the at least one thread passes through at least one flexible tube between said free part of the at least two anchor pieces.

19. A prosthesis according to claim 1, wherein the frame is fixed to an outer surface of said mesh.

20. A prosthesis according to claim 1, wherein the frame is rigid and the hinge points do not have any elasticity.

21. A prosthesis according to claim 20, wherein the prosthesis is configured to adopt only two configurations including a flat and spread out first configuration and a fold evenly in two configuration.

22. A prosthesis comprising:

at least one flexible mesh delimited by a peripheral exterior edge,

at least one member for reinforcing said mesh, said reinforcing member taking the form of a frame fastened to said mesh and substantially adopting a shape of said peripheral exterior edge of the mesh, said frame being set back from said peripheral exterior edge and defining an inner perimeter, the frame being provided with two hinge points, a folding line passing through said two hinge points also passing through a center of the mesh for folding the mesh in two

wherein said prosthesis further comprises at least two anchor pieces located on a single face of the mesh on either side of said line, each anchor piece is in a form of a triangular textile having a fixed part linked to said mesh via a base of the triangular textile located along the inner perimeter of the frame and a free part, said free part being linked to at least one thread-shaped element.
