Abstract

An implant including a vaginal portion having a length, width, first and second ends with a central region positioned therebetween, and a sacral portion having a length, width, first end and second end. The first end of the sacral portion is coupled to the central region of the vaginal portion so that the width of the first end extends substantially perpendicularly to the length of the vaginal portion. The implant is made of the same substantially flat, planar mesh having an anisotropic knitted or woven structure that has a greater stiffness in a first direction than a second direction. The mesh is aligned such that the first direction is aligned in a longitudinal direction of the sacral portion and the mesh of the vaginal portion is aligned such that the stiffness in a longitudinal direction of the vaginal portion is less than that of the sacral portion.

First claim

What is claimed is:

1. A surgical implant comprising:
a vaginal portion having a length, a width, a first end and a second end, and a central region positioned between the first and second ends;
a sacral portion having a length, a width, a first end and a second end, wherein the first end of the sacral portion is coupled to the central region of the vaginal portion, wherein the width of the sacral portion extends perpendicularly to the length of the vaginal portion, and wherein the length of the sacral portion is aligned with the length of the vaginal portion;
wherein the vaginal and sacral portions are comprised of the same flat, planar mesh material having uniform properties throughout said implant and having an anisotropic knitted or woven structure that has a greater stiffness in a first direction than a second direction, and wherein the first direction of the anisotropic mesh structure of the sacral portion is aligned with the length of the sacral portion and the first direction of the anisotropic mesh structure of the vaginal portion is not aligned with the length of the vaginal portion, and wherein the stiffness of the vaginal portion along its length is less than that of the sacral portion along its length.

2. The surgical implant according to claim 1 , wherein the mesh is a partially absorbable mesh.

3. The surgical implant according to claim 2 , wherein the mesh is comprised of an equal mass of poliglecaprone-25 monofilament fibers and absorbable polypropylene monofilament fibers.

4. The surgical implant according to claim 1 , wherein the mesh of the vaginal portion is oriented in a direction that is perpendicular to a direction of orientation of the mesh of the sacral portion.

5. The surgical implant according to claim 1 , further comprising an absorbable film coupled to at least the sacral portion of the mesh.

6. The surgical implant according to claim 1 , wherein the sacral portion is coupled to the vaginal portion by a sewn seam.

7. The surgical implant according to claim 1 , wherein the sacral portion is coupled to the vaginal portion by a laser weld.

8. The surgical implant according to claim 1 , wherein the length and width of the sacral portion is 14 cm and 3 cm respectively.

9. The surgical implant according to claim 8 , wherein the length and width of the vaginal portion is 13 cm and 5 cm respectively.

10. A surgical implant comprising:
a vaginal portion having a length, a width, a first end and a second end, and a central region positioned between the first and second ends, the vaginal portion being comprised of a mesh material having a knit or weave pattern oriented in a first direction;
a sacral portion having a length, a width, a first end and a second end, the first end of the sacral portion being coupled to the central region of the vaginal portion, wherein the width of sacral portion extends perpendicularly to the length of the vaginal portion, the sacral portion being comprised of the same mesh material as the vaginal portion, and the knit or weave pattern of the mesh material of the sacral portion is oriented in a second direction that is different than said first direction of orientation of said mesh material of said vaginal portion.

11. The surgical implant according to claim 10 , wherein the second direction is perpendicular to the first direction.

12. The surgical implant according to claim 10 , wherein the mesh is a partially absorbable mesh.

13. The surgical implant according to claim 12 , wherein the mesh is comprised of an equal mass of poliglecaprone-25 monofilament fibers and absorbable polypropylene monofilament fibers.

14. The surgical implant according to claim 10 , further comprising an absorbable film coupled to at least the sacral portion of the mesh.

15. The surgical implant according to claim 10 , wherein the length and width of the sacral portion is 14 cm and 3 cm respectively.

16. The surgical implant according to claim 15 , wherein the length and width of the vaginal portion is 13 cm and 5 cm respectively.
