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.

Claims

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, the first end of the sacral portion being 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;

wherein the vaginal and sacral portions are comprised of the same substantially flat, planar mesh having substantially 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 mesh of the sacral mesh portion 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.

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 a substantially 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 first direction and the mesh of the sacral portion is oriented in a second direction that is substantially perpendicular to the first direction.

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 approximately 14 cm and 3 cm respectively.

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

10. The surgical implant according to claim 1, wherein the vaginal portion is comprised of a first vaginal flap extending from the central region to the first end, and a second vaginal flap extending from the central region to the second end, and wherein at least one of the first and second vaginal flaps is biased to overlay the sacral portion when the implant is unconstrained.

11. 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 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 so that the width of the first end extends substantially perpendicularly to the length of the vaginal portion, the sacral portion being comprised of the same mesh as the vaginal portion, and having a knit or weave pattern oriented in a second direction different than said first direction.

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

13. The surgical implant according to claim 11, wherein the mesh is a partially absorbable mesh.

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

15. The surgical implant according to claim 11, further comprising an absorbable film coupled to at least the sacral portion of the mesh.

16. The surgical implant according to claim 11, wherein the length and width of the sacral portion is approximately 14 cm and 3 cm respectively.

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

18. The surgical implant according to claim 11, wherein the vaginal portion is comprised of a first vaginal flap extending from the central region to the first end, and a second vaginal flap extending from the central region to the second end, and wherein at least one of the first and second vaginal flaps is biased to overlay the sacral portion when the implant is unconstrained.

19. A surgical implant comprising:

a vaginal portion having a length, a width, a first end, a second end, and a central region positioned between the first and the second ends, the vaginal portion including a first vaginal flap portion extending from the central region and terminating at said first end, and a second vaginal flap portion extending from the central region and terminating at said second end;

a sacral portion having a length, a width, a first end and a second end, the first end being coupled to the central region of the vaginal portion so that the first end of the sacral portion extends substantially perpendicularly to the length of the vaginal portion;

wherein at least the first vaginal flap is biased to substantially overlay the sacral portion when unconstrained.

20. The surgical implant according to claim 19, wherein the implant is comprised of a mesh.

21. The surgical implant according to claim 20, wherein the mesh is partially absorbable.

22. The surgical implant according to claim 21, wherein the mesh is comprised of a substantially equal mass of poliglecaprone-25 monofilament fibers and absorbable polypropylene monofilament fibers.

23. The surgical implant according to claim 20, wherein the length and width of the sacral portion is approximately 14 cm and 3 cm respectively.

24. The surgical implant according to claim 23, wherein the length and width of the vaginal portion is approximately 13 cm and 5 cm respectively.

25. The surgical implant according to claim 19, wherein at least one of the first and second vaginal flaps is biased to overlay the sacral portion when the implant is unconstrained.
