Abstract

The invention relates to a prosthesis (1) for the repair of an inguinal hernia comprising:

• • a textile (2) of elongate shape,
  • a resilient frame (3) connected to said textile,
    characterized in that said frame comprises a convex cranial segment (3c), a caudal segment (3d),
  • a lateral corner segment (3b) joining together the convex cranial segment and the caudal segment, and a folding segment (5) joining a medial end of said convex cranial segment to a point located on the caudal segment while leaving the region of the medial end of the textile free of any frame,
  • said frame being able to adopt an unstressed configuration, in which said textile is deployed, and a stressed configuration, in which said convex cranial segment, said caudal segment and said folding segment are substantially collected together and aligned on one folding direction, said textile forming thereby at least one fold along said folding direction.

Claims

1. A prosthesis for the repair of an inguinal hernia, of generally elongate shape defining a longitudinal axis aligned on a medial-lateral axis and a transversal axis aligned on a cranial-caudal axis comprising:

at least one flexible biocompatible textile of elongate shape comprising a medial end, a lateral end, a cranial part and a caudal part, the textile delimited by a peripheral outer edge formed of a convex medial edge, a convex cranial edge, a convex lateral edge and a caudal edge, and,

at least one reinforcing element for the textile, the reinforcing element in the form of a resilient frame connected to the textile and set back from the peripheral outer edge, wherein the frame comprises a convex cranial segment extending from the medial end of the textile to the lateral end of the textile along the convex cranial edge, a caudal segment substantially extending from the medial end of the textile to the

lateral end of the textile and caudally spaced with respect to the convex cranial segment, a lateral corner segment joining together the convex cranial segment and the caudal segment in the lateral end of the textile, a folding segment configured for joining a medial end of the convex cranial segment to a point located on the caudal segment while leaving a region of the medial end of the textile free of any frame, and a caudal extension located on the caudal segment and extending in a caudal direction toward the caudal edge of the textile.

2. The prosthesis of claim 1, wherein the frame is configured to adopt an unstressed configuration, in which the textile is deployed, and a stressed configuration, in which the frame is subjected to a transversal force directed towards the longitudinal axis and the convex cranial segment, the caudal segment and the folding segment are substantially collected together and aligned on one folding direction, the textile forming thereby at least one fold along the folding direction.

3. The prosthesis according to claim 2, wherein the lateral corner segment is linked to the convex cranial segment and to the caudal segment via two respective hinge points allowing the lateral region of the textile to be folded onto the remaining part of the textile.

4. The prosthesis according to claim 2, further comprising a deploying element located in a region of the medial end of the textile, for drawing away the convex cranial segment from the caudal segment when the transversal force is released and the textile is being deployed.

5. The prosthesis according to claim 4, wherein the deploying element is located inside a mouth defined by the folding segment and optionally the caudal segment.

6. The prosthesis according to claim 5, wherein the deploying element located inside the mouth is a tooth separate from the frame.

7. The prosthesis according to claim 5, wherein the deploying element located inside the mouth is an arrow separate from the frame.

8. The prosthesis according to claim 1, wherein the caudal extension includes undulations.

9. The prosthesis according to claim 1, wherein the caudal segment is concave.

10. The prosthesis according to claim 1, wherein the folding segment joins the medial end of the convex cranial segment to a medial end of the caudal segment.

11. The prosthesis according to claim 1, wherein the folding segment has a U shape extending towards a center of the textile.

12. The prosthesis according to claim 1, wherein the frame is continuous.

13. The prosthesis according to claim 1, wherein at least a part of the caudal segment has substantially the structure of a flat band forming undulations substantially in the plane of the textile.

14. The prosthesis according to claim 1, wherein the reinforcing element is molded over the textile.

15. The prosthesis according to claim 1, wherein the reinforcing element is made of bioresorbable material.

16. The prosthesis according to claim 1, in which the textile is a mesh.

17. The prosthesis according to claim 1, further comprising a grasping element capable of cooperating with a part of a grasping tool so as to temporarily couple the prosthesis to the tool.

18. The prosthesis according to claim 1, wherein the textile is bioresorbable.

19. The prosthesis according to claim 1, wherein the cranial part and the caudal part are asymmetrical.

20. The prosthesis according to claim 1, wherein the caudal edge is convex.

21. The prosthesis according to claim 1, wherein the caudal edge is flat.

22. A prosthesis for the repair of an inguinal hernia, of generally elongate shape defining a longitudinal axis aligned on a medial-lateral axis and a transversal axis aligned on a cranial-caudal axis comprising:

at least one flexible biocompatible textile of elongate shape comprising a medial end, a lateral end, a cranial part and a caudal part, the textile being delimited by a peripheral outer edge formed of a convex medial edge, a convex cranial edge, a convex lateral edge and a caudal edge, and,

at least one reinforcing element for the textile, the reinforcing element being in the form of a resilient frame connected to the textile and set back from the peripheral outer edge, wherein the frame comprises a convex cranial segment extending from the medial end of the textile to the lateral end of the textile along the convex cranial edge, a caudal segment substantially extending from the medial end of the textile to the

lateral end of the textile and caudally spaced with respect to the convex cranial segment, a lateral corner segment joining together the convex cranial segment and the caudal segment in the lateral end of the textile, a folding segment configured for joining the convex cranial segment to a first point located on the caudal segment while leaving a region of the medial end of the textile free of any frame, and a caudal extension located on a second point of the caudal segment and extending in a caudal direction toward the caudal edge of the textile, the first point being medially spaced to the second point of the caudal segment.
