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 method of repairing a hernia defect, comprising:
positioning a hernia repair patch against a tissue or muscle wall including the hernia defect, the hernia repair patch including a patch body and a mount releasably attached to the patch body, the mount holding a support member to assist in unfurling the hernia repair patch from a reduced configuration into an expanded configuration, the mount having an annular configuration with an open interior overlying a substantial portion of the patch body, the mount including one or more reliefs configured to allow the support member to deform in response to manipulation of the mount;
fixing the patch body to the tissue or muscle wall; and
detaching the mount holding the support member from the patch body.

2. The method recited in claim 1 , further including the act of removing the detached mount holding the support member through a narrow incision or cannula.

3. The method recited in claim 1 , further including the act of manipulating the hernia repair patch into a reduced configuration and the act of delivering the hernia repair patch in the reduced configuration through a narrow incision or cannula into a patient.

4. The method recited in claim 1 , wherein the patch body includes a first surface configured to allow tissue ingrowth and a second surface configured to inhibit adhesion formation.

5. The method recited in claim 1 , wherein the mount is releasably attached to the patch body with a continuous suture, and including the act of pulling the mount away from the patch body.

6. The method recited in claim 5 , further including the act of severing the continuous suture before pulling the mount away from the patch body.

7. The method recited in claim 1 , wherein the mount includes a sleeve that contains the support member.

8. The method recited in claim 1 , wherein the mount generally follows the periphery of the patch body.

9. The method recited in claim 1 , wherein the mount has inner and outer peripheries, the inner periphery defining the open interior.

10. The method recited in claim 1 , wherein each relief has a V-shape bend.

11. The method recited in claim 1 , wherein the mount includes separate first and second layers of material with the support member located therebetween.

12. A method of repairing a hernia defect, the method comprising:
positioning a hernia repair patch against a tissue or muscle wall including the hernia defect, the hernia repair patch including a patch body and a mount releasably attached to the patch body, the patch body including a pair of tabs extending outwardly from opposed sides of the patch body, the mount holding a support member to assist in unfurling the hernia repair patch from a reduced configuration into an expanded configuration;
fixing the patch body to the tissue or muscle wall and further including the act of fixing each of the tabs to the tissue or muscle wall; and
detaching the mount holding the support member from the patch body.

13. A method of repairing a hernia defect, the method comprising:
positioning a hernia repair patch against a tissue or muscle wall including the hernia defect, the hernia repair patch including a patch body and a mount releasably attached to the patch body, the mount holding a support member to assist in unfurling the hernia repair patch from a reduced configuration into an expanded configuration, the support member including a deforming force reducer;
fixing the patch body to the tissue or muscle wall; and
detaching the mount holding the support member from the patch body, the act of detaching includes bending the support member at the deforming force reducer.

14. The method recited in claim 13 , wherein the deforming force reducer includes an inward deflection of the support member.

15. The method recited in claim 13 , wherein the mount includes a sleeve that contains the support member, and wherein the sleeve includes a relief at the location of the deforming force reducer of the support member contained within the sleeve.

16. A method of arranging a hernia repair patch for delivery into a patient, comprising:
positioning the hernia repair patch within a patch receiving area of an introducer having an opening, the hernia repair patch having an edge portion including a stop that is not passable through the opening to the patch receiving area, the stop being located on one side of the introducer and a second portion of the patch located on another side of the introducer.

17. The method recited in claim 16 , further including manipulating the hernia repair patch about the introducer into a reduced configuration suitable for delivery through a narrow incision or cannula into a patient.

18. The method recited in claim 17 , wherein the act of manipulating includes rolling the second portion of the hernia repair patch about the introducer.

19. The method recited in claim 18 , wherein the act of rolling the second portion of the hernia repair patch includes rotating the introducer.
