Abstract

A surgical implant suitable for treatment of hernias includes a mesh having a residual maximum mass density of 5O g/m<2>. The mesh has strands forming spaces and the strands define filaments forming pores. The spaces and pores are sized to minimize foreign body mass for implantation and to encourage integration of the implant. The mesh may be delivered using Dual Phase Technology for ease of handling, cutting and placement. The Dual Phase Technology may include encapsulation or coating with hydrogel.

Claims

1. A method of providing support to the pelvic floor of a patient, the method comprising the steps of:

making an incision in the vaginal wall to expose the area of a pelvic floor prolapse selected from the group consisting of urethrocoele prolapse, cystocoele prolapse, vault prolapse, uterine prolapse, enterocoele prolapse, and rectocoele prolapse;

forming a space in the tissues;

inserting through the incision into the space in the tissues an implant comprising a mesh having a mass density of 20 g/m² or less; and

implanting the mesh in the area of the pelvic floor prolapse to provide support to the pelvic floor area.

2. The method of claim 1, wherein the method of providing support to the pelvic floor is a method for treating a uterovaginal prolapse.

3. The method of claim 2, wherein the incision over the area of the pelvic floor prolapse is at the posterior extremity of the prolapse sac of the vaginal cavity.

4. The method of claim 2, wherein the incision over the area of the pelvic floor prolapse is at the anterior extremity of the prolapse sac of the vaginal cavity.

5. The method of claim 1, wherein implanting the mesh comprises implanting without suturing.

6. The method of claim 1, wherein implanting the mesh comprises adhering the mesh to the tissues.

7. The method of claim 1, further comprising introducing said mesh with a tool through the vaginal incision.

8. The method of claim 1, further comprising unrolling said mesh.

9. The method of claim 1, wherein implanting said mesh is performed without sutures.

10. The method of claim 1, wherein said implant comprises a plurality of pores.

11. The method of claim 1, wherein said mesh comprises polypropylene.

12. The method of claim 1, wherein said mesh comprises polyester.

13. The method of claim 1, wherein said mesh is knit.

14. The method of claim 13, wherein said knit comprises a warp knit.

15. The method of claim 1, wherein said mesh is woven.

16. The method of claim 1, wherein the pelvic floor prolapse is overlain by the lower one-third of the anterior vagina.

17. The method of claim 1, wherein the pelvic floor prolapse is overlain by the upper two-thirds of the anterior vagina.

18. The method of claim 1, wherein the pelvic floor prolapse is overlain by the vaginal vault or uterus.

19. The method of claim 1, wherein the pelvic floor prolapse is overlain by the upper one-third of the posterior vagina.

20. The method of claim 1, wherein the pelvic floor prolapse is overlain by the lower two-thirds of the posterior vagina.

21. The method of claim 1, wherein the pelvic floor prolapse is urethrocoele prolapse.

22. The method of claim 1, wherein the pelvic floor prolapse is cystocoele prolapse.

23. The method of claim 1, wherein the pelvic floor prolapse is vault prolapse.

24. The method of claim 1, wherein the pelvic floor prolapse is uterine prolapse.

25. The method of claim 1, wherein the pelvic floor prolapse is enterocoele prolapse.

26. The method of claim 1, wherein the pelvic floor prolapse is rectocoele prolapse.
