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.

Claims

1. A device for performing surgery on a patient, the device comprising:

a mesh patch comprising a top surface and a bottom surface, the bottom surface having a plurality of hooks positioned thereon; and

a removable cover positioned adjacent to and in facing engagement with the bottom surface of the mesh patch,

wherein 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.

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 the 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 layer of smooth polymeric material.

6. The device of claim 1, wherein the surgical site is a portion of an abdominal wall in a groin area of a patient.

7. A kit for surgical repair comprising:

a mesh patch comprising a top surface and a bottom surface, the bottom surface having a plurality of hooks positioned thereon; and

a removable cover configured to be positioned adjacent to and in facing engagement with the bottom surface of the mesh patch,

wherein 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.

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 patch.

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

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

12. The kit of claim 11, wherein the hooks are prepared from polylactic acid (PLA).

13. The kit of claim 7, wherein the cover comprises a layer of smooth polymeric material.

14. The kit of claim 7, wherein the surgical site is a portion of an abdominal wall in a groin area of a patient.

15. A method for repairing an abdominal wall hernia comprising the steps of:

a) cutting a transverse oblique 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 and a bottom surface, the bottom surface having a plurality of hooks positioned thereon; and

a removable cover having a first side positioned on the bottom surface 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 the surrounding tissue and secure the mesh patch to the surgical site; and

h) closing the incision with stitches.

16. The method of claim 15, further comprising the step of lining the surgical site with pieces of a sheet of polymeric material prior to step e).

17. The method of claim 15, wherein the top surface of the mesh fabric comprises polyester, polypropylene, or any combination thereof.

18. The method of claim 15, wherein the hooks comprise a bioresorbable material.

19. The method of claim 18, wherein the hooks are prepared from poylactic acid (PLA).

20. The method of claim 15, wherein the cover comprises a layer of smooth polymeric material.

21. A surgical combination comprising:

a mesh patch comprising a top surface and a bottom surface, the bottom surface having a plurality of hooks positioned thereon; and

a removable cover positioned adjacent to and in facing engagement with the bottom surface of the mesh patch,

wherein 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.

22. The surgical combination of claim 21, wherein the top surface of the mesh patch comprises polyester, polypropylene, or any combination thereof

23. The surgical combination of claim 21, wherein the hooks comprise a bioresorbable material.

24. The surgical combination of claim 23, wherein the hooks are prepared from polylactic acid (PLA).

25. The surgical combination of claim 21, wherein the cover comprises a layer of smooth polymeric material.
