Abstract

A device for performing surgery on a patient includes: a mesh patch comprising a top surface and a bottom surface; and a removable cover positioned adjacent to and in facing engagement with the bottom surface of the mesh patch. The bottom surface has a plurality of hooks positioned thereon. The cover is removed from the mesh patch as the mesh patch is positioned at a surgical site such that the hooks on the bottom of the mesh patch grip surrounding tissue of a patient and secure the mesh patch to surrounding tissue of the surgical site. A method for performing a surgery using such a device is also provided.

First claim

The invention claimed is:

1. A device for performing surgery on a patient, the device comprising:
a mesh patch comprising a top surface, a bottom surface, and a first slit, the bottom surface having a plurality of hooks positioned thereon; and
a removable cover comprising a non-porous polymeric film, the removable cover positioned adjacent to and in facing engagement with the bottom surface of the mesh patch covering the plurality of hooks to prevent premature fixation of the plurality of hooks to a surgical site, wherein the removable cover includes a second slit which corresponds to the first slit provided in the mesh patch and the removable cover is slid laterally across the plurality of the hooks on the bottom surface of the mesh patch to expose the plurality of hooks on the bottom surface of the mesh patch to the surgical site.

2. The device of claim 1 , wherein the top surface of the mesh patch comprises polyester, polypropylene, or any combination thereof.

3. The device of claim 1 , wherein hooks comprise a bioresorbable material.

4. The device of claim 3 , wherein the hooks are prepared from polylactic acid (PLA).

5. The device of claim 1 , wherein the cover comprises a polyolefin.

6. The device of claim 1 , wherein the cover is removed from the mesh patch at a surgical site comprising a portion of an abdominal wall in a groin area of the patient.

7. A kit for surgical repair comprising:
a mesh patch comprising a top surface, a bottom surface, and a first slit, the bottom surface having a plurality of hooks positioned thereon; and
a removable cover comprising a non-porous polymeric film, the removable cover configured to be positioned adjacent to and in facing engagement with the bottom surface of the mesh patch, wherein the removable cover includes a second slit which corresponds to the first slit provided in the mesh patch and the removable cover is configured to slide laterally to expose the hooks on the bottom of the mesh patch.

8. The kit of claim 7 , further comprising an additional sheet of polymeric material.

9. The kit of claim 8 , wherein the sheet is configured to be cut into pieces by a surgeon to line the surgical site prior to positioning the cover and mesh patch.

10. The kit of claim 8 , wherein the additional sheet of polymeric material is made of the same material as the removable cover.

11. The kit of claim 7 , wherein the top surface of the mesh patch comprises polyester, polypropylene, or any combination thereof.

12. The kit of claim 7 , wherein the hooks comprise a bioresorbable material.

13. The kit of claim 12 , wherein the hooks are prepared from polylactic acid (PLA).

14. The kit of claim 7 , wherein the cover comprises polypropylene.

15. The kit of claim 7 , wherein the cover is removed from the mesh patch at a surgical site comprising a portion of an abdominal wall in a groin area of the patient.

16. A method for repairing an abdominal wall hernia comprising:
a) cutting an incision in a fold of a groin of a patient;
b) widely dissecting a superficial inguinal space of the patient, thereby freeing fascial surfaces and creating a surgical site;
c) mobilizing a spermatic cord of the patient using a latex band;
d) repairing the abdominal wall hernia and making a relaxing incision in an internal oblique fascia of the patient;
e) providing a device comprising: a mesh patch comprising a top surface, a bottom surface and a first slit, the bottom surface having a plurality of hooks positioned thereon; and a removable cover comprising a non-porous polymeric film, the removable cover having a first side positioned on the bottom surface of the mesh patch and including a second slit which corresponds to the first slit provided in the mesh patch and the removable cover is configured to slide laterally to expose the hooks on the bottom of the mesh patch;
f) positioning the device over the surgical site such that a second side of the cover is adjacent to the surgical site;
g) removing the cover as the mesh patch is positioned at the surgical site such that the hooks on the bottom of the mesh patch grip surrounding tissue and secure the mesh patch to the surgical site; and
h) closing the incision with stitches.

17. The method of claim 16 , further comprising the step of lining the surgical site with pieces of a sheet of polymeric material prior to step e).

18. The method of claim 16 , wherein the top surface of the mesh patch comprises polyester, polypropylene, or any combination thereof.

19. The method of claim 16 , wherein the hooks comprise a bioresorbable material.

20. The method of claim 19 , wherein the hooks are prepared from polylactic acid (PLA).

21. The method of claim 16 , wherein the cover comprises a polyolefin.

22. The method of claim 16 , wherein removing the cover comprises sliding the cover laterally to expose the hooks on the bottom of the mesh patch.

23. The method of claim 16 , wherein the mesh patch further comprises a flap.
