Abstract

The present invention is an implantable adhesive mesh prosthesis for reinforcing and/or repairing a defect in tissue that is easy to roll into a small diameter cylinder or other low-profile shape for passing through a trocar, incision, or other surgical instrument. More specifically, the adhesive may be applied to the mesh material in a pattern that leaves a significant portion of the surface area of the mesh material free of adhesive. In one embodiment, the adhesive is applied only near the outer perimeter of the mesh product. In another embodiment, the adhesive is applied in spots over all or a portion the surface of the mesh product. In yet another embodiment, the adhesive is applied in parallel lines on the surface of the mesh product and the mesh may be rolled up around an axis parallel to the lines of adhesive.

Claims

1. An implantable, self-adhering mesh prosthesis for repairing animal tissue comprising;

a sheet of mesh material comprising first and second opposing major surfaces; and

adhesive disposed on a portion of at least the first major surface of the sheet, the portion comprising less than a whole of the first major surface.

2. The prosthesis of claim 1 wherein the portion comprises a band around a perimeter of the first major surface.

3. The prosthesis of claim 1 wherein the portion comprises a plurality of spots interspersed between areas of the first major surface bearing no adhesive.

4. The prosthesis of claim 1 wherein the portion comprises a plurality of parallel lines.

5. The prosthesis of claim 4 wherein each parallel line is continuous.

6. The prosthesis of claim 4 wherein each parallel line is intermittent.

7. The prosthesis of claim 3 wherein the spots are distributed on the first surface so that, when the sheet is rolled into a cylindrical tube, the spots substantially do not overlap each other in a longitudinal direction of the cylindrical tube.

8. The prosthesis of claim 3 wherein the spots are distributed on the first surface so that, when the sheet is rolled into a cylindrical tube, the spots are minimally overlapping in a longitudinal direction of the cylindrical tube.

9. The prosthesis of claim 3 wherein the spots comprise a plurality of parallel lines and the lines are distributed on the first surface so that, when the sheet is rolled into a cylindrical tube about a longitudinal axis parallel to the lines having a diameter as small as possible without damaging the prosthesis, all of the lines are radially offset from each other around the longitudinal axis.

10. The prosthesis of claim 1 wherein the sheet comprises at least one layer of woven threads having ends adjacent an edge of the sheet and wherein the ends of the threads are sealed within the adhesive.

11. The prosthesis of claim 3 wherein the spots are distributed on the first surface so that each spot is a different distance from a predetermined point on the first surface.

12. The prosthesis of claim 1 wherein the prosthesis is an inguinal hernia repair prosthesis.

13. The prosthesis of claim 1 wherein the sheet is three dimensional.

14. The prosthesis of claim 1 further comprising:

adhesive disposed on a portion of the second major surface of the sheet, the portion of the second major surface of the sheet bearing adhesive comprising less than a whole of the first major surface, and wherein none of the portion of the second major surface of the sheet that bears adhesive non-overlying any of the portion of the first major surface of the sheet that bears adhesive.

15. The prosthesis of claim 1 further comprising:

adhesive disposed on a portion of the second major surface of the sheet, the portion of the second major surface of the sheet bearing adhesive comprising less than a whole of the first major surface, and wherein the portion of the second major surface of the sheet that bears adhesive is opposed to the portion of the first major surface of the sheet that bears adhesive.

16. A method of implanting a self-adhering mesh prosthesis for repairing animal tissue, the method comprising:

providing a sheet of mesh material comprising first and second opposing major surfaces and adhesive disposed on a plurality of portions of at least the first major surface of the sheet, the plurality of portions comprising less than a whole of the first major surface;

folding the sheet for passage through a restricted passageway into an animal body, the sheet passing through the passageway in a longitudinal direction of the passageway, the folding being conducted so as to minimize overlap of the portions that bear adhesive with each other in the transverse plane;

passing the sheet through the passageway;

unfolding the sheet after passage through the passageway; and

adhering the sheet to tissue in the animal body.

17. The method of claim 16 wherein, when folded, the portions that bear adhesive do not overlap with each other in the transverse plane.

18. The method of claim 16 wherein the portions that bear adhesive comprise a plurality of spots interspersed between areas of the first major surface bearing no adhesive, and wherein the spots are distributed on the first surface so that each spot is a different distance from a predetermined point on the first surface and wherein the passing comprises grasping the sheet at the predetermined point and pushing the sheet through the passageway with the predetermined point on the sheet leading and the remainder of the sheet trailing behind the predetermined point.

19. The method of claim 16 wherein the portion comprises a plurality of parallel lines and wherein the folding comprises rolling the sheet into a cylindrical tube about an axis parallel to the lines of adhesive such that the lines of adhesive are radially offset from each other around the longitudinal axis.

20. The method of claim 16 wherein the sheet comprises at least one layer of woven threads having ends adjacent an edge of the sheet and further comprising:

sealing the ends of the threads with at least some of the adhesive portions.
