Abstract

Herniation, including cystocele, rectocele and enterocystocele may be treated with prefabricated repair patches. The repair patches include a natural or synthetic biocompatible material having a shape adapted to support herniated tissue. The patch also contains a plurality of apertures positioned in the central plane of the patch which may permit ingrowth and may also be an attachment site for pexing sutures. The patch may be covered with coating to decrease the possibility of infection, and/or increase biocompatibility. The coating may also include one or more drugs, for example, an antibiotic, an immunosuppressant, and/or an anticoagulant.

Claims

1. A surgical patch comprising a piece of biocompatible material including a plurality of apertures and four corners, each corner being adapted to be attached to an anatomical structure by a surgical fastener, thereby forming a first force line extending from one of the corners to a diagonally opposite one of the corners and a second force line extending from a different one of the corners to diagonally opposite one of the corners, wherein none of the plurality of apertures intersects the first force line or the second force line.

2. The surgical patch of claim 1 wherein at least one of the plurality of apertures comprises a substantially circular hole in the piece of material.

3. The surgical patch of claim of 1 wherein the piece of material is capable of being trimmed with scissors.

4. The surgical patch of claim 1 wherein the biocompatible material includes a plurality of interstices.

5. The surgical patch of claim 1 wherein the apertures permit tissue ingrowth after the patch is installed in a body.

6. The surgical patch of claim 1 wherein the apertures are reinforced.

7. The surgical patch of claim 1 wherein the sides form a trapezoidal shape.

8. The surgical patch of claim 1 wherein the apertures are located in the central portion of the piece of material away from the sides.

9. The surgical patch of claim 1 wherein the piece of material comprises a knitted material.

10. The surgical patch of claim 9 wherein the knitted material comprises a polymer.

11. The surgical patch of claim 1 wherein the patch is capable of releasing a drug.

12. The surgical patch of claim 1 wherein the piece of material includes a coating.

13. The surgical patch of claim 12 wherein the coating includes heparin.

14. The surgical patch of claim 12 wherein the coating includes an antibiotic.

15. The surgical patch of claim 12 wherein the coating comprises collagen.

16. The surgical patch of claim 12 wherein the coating comprises polyglycolic acid.

17. The surgical patch of claim 12 wherein the coating comprises polyactic acid.

18. The surgical patch of claim 12 wherein the coating comprises gelatin.

19. The surgical patch of claim 12 wherein the coating comprises polyvinyl alcohol.

20. The surgical patch of claim 12 wherein the coating comprises polyvinyl pyrrolidone.

21. The surgical patch of claim 12 wherein the coating is absorbable by a body.

22. The surgical patch of claim 1 wherein the piece of material is absorbable by a body.

23. The surgical patch of claim 1 wherein the surgical fastener includes a suture.

24. The surgical patch of claim 1, wherein the surgical patch includes a first end approximately 1.97 inches long and a second end approximately 2.17 inches long.

25. The surgical patch of claim 24, wherein the surgical patch includes third and fourth ends approximately 1.78 inches long.

26. The surgical patch of claim 1 wherein the apertures are approximately 0.17 inches in diameter.

27. The surgical patch of claim 1 wherein the apertures are spaced approximately 0.4 inches apart.

28. The surgical patch of claim 1, wherein the surgical patch applies a force sufficient to treat herniated tissue.

29. The surgical patch of claim 28, wherein the herniated tissue is a cystocele.

30. The surgical patch of claim 28, wherein the herniated tissue is a rectocele.

31. The surgical patch of claim 28, wherein the herniated tissue is a enterocele.

32. The surgical patch of claim 28, wherein the surgical fastener includes a bone anchor.

33. The surgical patch of claim 29, wherein the stable anatomical structure includes bone.
