Abstract

An implantable prosthesis for repairing an anatomical defect, such as a tissue or muscle wall hernia, including an umbilical hernia, and for preventing the occurrence of a hernia at a small opening or weakness in a tissue or muscle wall, such as at a puncture tract opening remaining after completion of a laparoscopic procedure. The prosthesis includes a patch and/or plug having a body portion that is larger than a portion of the opening or weakness so that placement of the body portion against the defect will cover or extend across that portion of the opening or weakness. At least one tether, such as a strap, extends from the patch or plug and may be manipulated by a surgeon to position the patch or plug relative to the repair site and/or to secure the patch or plug relative to the opening or weakness in the tissue or muscle wall. The tether may be configured to extend through the defect and outside a patient'"'"'s body to allow a surgeon to position and/or manipulate the patch from a location outside the body. An indicator may be provided on the tether as an aid for a surgeon in determining when the patch or plug has been inserted a sufficient distance within the patient. A support member may be arranged in or on the patch or plug to help deploy the patch or plug at the surgical site and/or help inhibit collapse or buckling of the patch or plug. The patch or plug may be configured with a pocket or cavity to facilitate the deployment and/or positioning of the patch or plug over the opening or weakness.

Claims

1. An implantable prosthesis for repairing an abdominal wall defect, the implantable prosthesis comprising:

a soft tissue repair patch;

a pair of straps extending away from the patch, each strap having a cross-section with a width and thickness, the width being greater than the thickness, each strap extending a sufficient length from the patch to extend through the abdominal wall defect when the patch is on one side of the defect, so that a portion of the strap is on the other side of the defect and adapted to be secured by an attachment device that includes a suture, staple or tack.

2. The implantable prosthesis of claim 1, wherein the repair patch includes a first mesh layer.

3. The implantable prosthesis of claim 2, wherein the repair patch further includes a barrier layer.

4. The implantable prosthesis of claim 3, wherein the repair patch further includes a second mesh layer located between the barrier layer and the first mesh layer.

5. The implantable prosthesis of claim 4, wherein at least one of the first mesh layer and the second mesh layer is absorbable.

6. The implantable prosthesis of claim 1, wherein the patch includes a support member.

7. The implantable prosthesis of claim 6, wherein the support member is located within the patch.

8. The implantable prosthesis of claim 6, wherein the support member includes a support ring.

9. The implantable prosthesis of claim 1, wherein each strap has a length of from approximately 2.5 inches to approximately 20 inches.

10. The implantable prosthesis of claim 1, wherein the defect is one of an umbilical hernia, incisional hernia or a trocar puncture.

11. The implantable prosthesis of claim 1, wherein the pair of straps are adapted to be pulled away from each other.

12. The implantable prosthesis of claim 1, wherein the pair of straps are adapted to lie flat relative to the patch.

13. The implantable prosthesis of claim 1, wherein each strap includes a layer of mesh fabric.

14. The implantable prosthesis of claim 1, wherein each strap is adapted to be pulled by a user to selectively position the patch to cover an opening to the defect.

15. The implantable prosthesis of claim 1, wherein the pair of straps form a loop extending away from the patch.

16. The implantable prosthesis of claim 1, wherein each strap is adapted for tissue infiltration.
