Abstract

The present disclosure relates to skirted hernia repair devices which includes at least a first mesh layer having a first side, a second side, and an outer peripheral edge, a skirt mesh layer positioned on the first side of the first mesh layer, the skirt mesh layer having an inner peripheral edge defining an opening in the skirt mesh layer, and, at least one reinforcement member that prevents the skirt mesh layer from inverting.

First claim

What is claimed is:

1. A method for repairing a tissue defect, the method comprising the steps of:
positioning a skirted hernia repair device within a tissue defect such that a first mesh layer of the skirted hernia repair device extends across the tissue defect, the skirted hernia repair device including:
the first mesh layer having a first side, a second side, and an outer peripheral edge;
a skirt mesh layer positioned on the first side of the first mesh layer forming a pocket between the first side and the skirt mesh layer, the skirt mesh layer having an inner peripheral edge defining an opening in the skirt mesh layer; and,
a plurality of reinforcement members that connect the first mesh layer to the skirt mesh layer near the inner peripheral edge to prevent the skirt mesh layer from inverting;

sliding a fastening device laterally across the first side of the first mesh layer and into the pocket; and,
securing the skirted hernia repair device to tissue, after sliding the fastening device, by firing the fastening device through the skirt mesh layer from inside the pocket.

2. The method of claim 1 , wherein the skirted hernia repair device further comprises an adhesion barrier film positioned on the second side of the first mesh layer.

3. The method of claim 1 , wherein the skirted hernia repair device further comprises an adhesion barrier film positioned on an outer surface of the skirt mesh layer opposite the pocket.

4. The method of claim 1 , wherein the skirted hernia repair device further comprises an adhesion barrier film positioned on an inner surface of the skirt mesh layer and a portion of the first side of the first mesh layer inside the pocket.

5. The method of claim 1 , wherein the plurality of reinforcement members are positioned within the pocket.

6. The method of claim 1 , wherein the plurality of reinforcement members are symmetrically positioned around the inner peripheral edge.

7. The method of claim 1 , wherein an outer peripheral edge of skirt mesh layer is aligned with an outer peripheral edge of the first mesh layer.

8. The method of claim 1 , wherein the device includes only one single pocket and the plurality of reinforcement members are positioned with the one single pocket.

9. The method of claim 1 , wherein the first mesh layer has a surface area that is at least 1.5 times larger than a surface area of the skirt mesh layer.

10. The method of claim 1 , wherein the first mesh layer is a three dimensional knit and the skirt mesh layer is a two dimensional knit.

11. The method of claim 1 , wherein the method for repairing a tissue defect is an intraperitoneal onlay procedure.

12. A method for repairing a tissue defect, the method comprising the steps of:
positioning a skirted hernia repair device within a tissue defect such that a first mesh layer of the skirted hernia repair device extends across the tissue defect, the skirted hernia repair device including:
the first mesh layer having a first side, a second side, and an outer peripheral edge;
a skirt mesh layer positioned on the first side of the first mesh layer forming a pocket between the first side and the skirt mesh layer, the skirt mesh layer having an inner peripheral edge defining an opening in the skirt mesh layer; and,
a plurality of reinforcement members that connect the first mesh layer to the skirt mesh layer near the inner peripheral edge to prevent the skirt mesh layer from inverting; and,

securing the skirted hernia repair device to tissue, wherein the plurality of reinforcement members each include a polymeric tab extending from the skirt mesh layer inwardly towards a center of the first side of the first mesh layer over the inner peripheral edge and onto a portion of the first side of the first mesh layer inside the opening, wherein each polymeric tab includes an edge configured to guide a fastening device into the pocket formed between the skirt mesh layer and the first mesh layer.

13. The method of claim 12 , wherein securing the skirted hernia repair device to tissue includes delivering a fastener in the vicinity of the pocket and through the device.

14. A method for repairing a tissue defect, the method comprising the steps of:
positioning a skirted hernia repair device within a tissue defect such that a first mesh layer of the skirted hernia repair device extends across the tissue defect, the skirted hernia repair device including:
the first mesh layer having a first side, a second side, and an outer peripheral edge;
a skirt mesh layer positioned on the first side of the first mesh layer forming a pocket between the first side and the skirt mesh layer, the skirt mesh layer having an inner peripheral edge defining an opening in the skirt mesh layer; and,
a plurality of reinforcement members that connect the first mesh layer to the skirt mesh layer near the inner peripheral edge to prevent the skirt mesh layer from inverting; and,

securing the skirted hernia repair device to tissue, wherein the plurality of reinforcement members include a first pair of first and second reinforcement members each having a first end extending from the inner peripheral edge of the skirt mesh layer to an outer peripheral edge of skirt mesh layer, wherein the second ends of the first and second reinforcement members of the first pair are closer to each other than the first ends of the first and second reinforcement members of the first pair.

15. The method of claim 14 , wherein the plurality of reinforcement members further include a second pair of first and second reinforcement members each having a first end extending from the inner peripheral edge of the skirt mesh layer to an outer peripheral edge of skirt mesh layer, wherein the second ends of the first and second reinforcement members of the second pair are closer to each other than the first ends of the first and second reinforcement members of the second pair.

16. A method for repairing a tissue defect, the method comprising the steps of:
positioning a skirted hernia repair device within a tissue defect such that a first mesh layer of the skirted hernia repair device extends across the tissue defect, the skirted hernia repair device including:
the first mesh layer having a first side, a second side, and an outer peripheral edge;
a skirt mesh layer positioned on the first side of the first mesh layer forming a pocket between the first side and the skirt mesh layer, the skirt mesh layer having an inner peripheral edge defining an opening in the skirt mesh layer; and,
a plurality of reinforcement members that connect the first mesh layer to the skirt mesh layer near the inner peripheral edge to prevent the skirt mesh layer from inverting; and,

securing the skirted hernia repair device to tissue, wherein the plurality of reinforcement members include a plurality of distinct reinforcement members positioned intermittently around the inner peripheral edge, the plurality of reinforcement members fixedly attaching the first mesh layer to the skirt mesh layer to prevent the pocket from inverting, wherein the plurality of reinforcement members are free of the inner peripheral edge and free of the outer peripheral edge, wherein the skirt mesh layer is spaced apart from the first mesh layer along the pocket creating a void therebetween, the void being positioned on both sides of the plurality of reinforcement members and extending to the opening.
