Abstract

A patch for repairing a hernia defect including a patch body that is reducible into a small configuration for delivery through a narrow incision or cannula into a patient. A support member assists in unfurling the patch body from the small configuration into an expanded configuration. A sleeve releasably mounts the support member to the patch body.

First claim

What is claimed is:

1. A patch for repairing a hernia, comprising:
a patch body having a periphery, a first axis and a second axis perpendicular to the first axis, the first axis and the second axis intersecting at approximately a center of the patch body, the patch body configured to be manipulated into a reduced configuration for insertion through a narrow incision or cannula into a patient;
a support member to assist unfurling the patch body from the reduced configuration to an expanded configuration; and
a mount that holds the support member, the mount including a sleeve that contains the support member, the sleeve being removably attached to the patch body, the support member being contained by the sleeve when the sleeve is detached from the patch body.

2. The hernia repair patch of claim 1 , wherein the sleeve is a flat sleeve.

3. The hernia repair patch of claim 1 , wherein the mount is removably attached to the patch body with a continuous suture.

4. The hernia repair patch of claim 1 , wherein the support member includes at least one abrupt inward deflection.

5. The hernia repair patch of claim 4 , wherein the at least one abrupt inward deflection is located along the first axis or the second axis.

6. The hernia repair patch of claim 4 , wherein the at least one abrupt inward deflection has a V-shape.

7. The hernia repair patch of claim 4 , wherein the at least one abrupt inward deflection includes a pair of abrupt inward deflections, each of the abrupt inward deflections located along one of the first axis and the second axis.

8. The hernia repair patch of claim 1 , wherein the sleeve includes one or more reliefs configured to facilitate bending of the sleeve and the contained support member in response to a pulling force applied to the sleeve.

9. The hernia repair patch of claim 8 , wherein the support member includes at least one inward deflection and the sleeve includes at least one relief adjacent the at least one inward deflection.

10. The hernia repair patch of claim 8 , wherein the patch body includes a first surface configured to allow tissue ingrowth and a second surface configured to inhibit the formation of adhesions.

11. The hernia repair patch of claim 1 , wherein the sleeve generally follows the periphery of the patch body.

12. The hernia repair patch of claim 1 , wherein the support member extends generally about the periphery of the patch body.

13. A patch for repairing a hernia, comprising:
a patch body having a periphery, a first axis and a second axis perpendicular to the first axis, the first axis and the second axis intersecting at approximately a center of the patch body;
a frame-shaped support member contained within and generally following the periphery of the patch body, the support member having first and second opposed side portions that are intersected by the first axis, the patch body and the support member configured to be manipulated together along the second axis into a reduced configuration for insertion through a slender incision or cannula into a patient, the support member including a single pair of abrupt inward deflections, each of the first and second opposed side portions of the support member including one of the pair of abrupt inward deflections along a segment thereof that reduces resistance to manipulation of the support member in the direction of the second axis; wherein the frame-shaped support member is held by a mount releasably attached to the patch body.

14. The hernia repair patch of claim 13 , wherein each of the abrupt inward deflections is located along the first axis.

15. The hernia repair patch of claim 13 , wherein each of the abrupt inward deflections has a V-shape.

16. The hernia repair patch of claim 13 , wherein the support member has a substantially oval or circular shape.

17. The hernia repair patch of claim 13 , wherein the opposed side portions bow outwardly away from the second axis.

18. The hernia repair patch of claim 13 , wherein each of the opposed side portions has a first end and a second end and a length between the first and second ends measured in a direction of the second axis, and each of the abrupt inward deflections has a first end and a second end and a length between the first end and second ends measured in the direction of the second axis, the length of each of the abrupt inward deflections ranging from 15-50% of the length of the opposed side portions.

19. The hernia repair patch of claim 13 , wherein the mount includes a sleeve.

20. The hernia repair patch of claim 13 , wherein the support member has a ring-like configuration.

21. The hernia repair patch of claim 20 , wherein the support member has a circular, oval or polygonal shape.

22. The hernia repair patch of claim 13 , wherein each of the first and second opposed side portions has outwardly curved segments extending from opposite ends of the abrupt inward deflection.

23. A patch for repairing a hernia, comprising:
a patch body having a first axis and a second axis perpendicular to the first axis, wherein the patch body is configured to be manipulated along the second axis into a reduced configuration for insertion through a narrow incision or cannula into a patient;
the patch body including an outer periphery with a second edge portion that is intersected by the second axis, the second edge portion having a first thickness;
a stop positioned along the second edge portion, the stop having a second thickness greater than the first thickness; and
an introducer having a patch receiving opening sufficiently large to admit the second edge portion but not sufficiently large to admit the stop.

24. The hernia repair patch of claim 23 , wherein the patch body includes a tissue ingrowth side and a barrier side, and the stop extends outwardly from the tissue ingrowth side.

25. The hernia repair patch of claim 24 , wherein the tissue ingrowth side includes a tissue infiltratable fabric and the barrier side includes a barrier layer or a barrier coating.

26. The hernia repair patch of claim 23 , wherein the stop is formed of a tissue infiltratable fabric.

27. The hernia repair patch of claim 26 , wherein the stop includes a plurality of layers of tissue of infiltratable fabric.

28. The hernia repair patch of claim 26 , wherein the stop includes a cylinder of tissue infiltratable fabric.

29. The hernia repair patch of claim 23 , wherein the patch body includes a pair of opposed second edge portions, a first stop is positioned at one of the opposed second edge portions and a second stop is positioned at the other of the opposed second edge portion, wherein the first stop and the second stop are offset in the direction of the second axis so as not to overlie one another when the patch body is manipulated along the second axis into a reduced configuration.

30. The hernia repair patch of claim 23 , further including a sleeve containing a support member, at least a portion of the sleeve extending along the second edge portion, wherein the stop is located on the portion of the sleeve extending along the second edge portion.

31. The hernia repair patch of claim 23 , wherein the introducer includes a shaft having a pair of splined sections, the patch receiving area defined between the pair of splined sections.

32. The hernia repair patch of claim 31 ,
