Abstract

The present disclosure relates to a surgical patch and methods of using the same. The surgical patch includes a body having a substrate, a longitudinal slit bisecting at least a portion of the body, and at least one additional slit extending from the longitudinal slit defining a retractable section. The surgical patch of the disclosure may be used, for example, to provide hemostasis at a site of anastomosis. The present disclosure also provides kits including such surgical patches, as well as templates that permit one to cut the patch to a desired size and/or shape.

Claims

1. A cutting template comprising:

a top portion possessing at least one slit forming a desired pattern;

a bottom portion possessing openings corresponding to the pattern in the top portion, the bottom portion further comprising a recessed region capable of holding a surgical patch therein; and

a means for connecting the top portion to the bottom portion.

2. The cutting template of claim 1, wherein the means for connecting the top portion to the bottom portion is selected from the group consisting of a catch, snap, hinge, interference fit, hinge, magnet, and combinations thereof.

3. The cutting template of claim 1, wherein the top portion and the bottom portion are connected to each other by a hinge.

4. The cutting template of claim 1, wherein the openings in the bottom portion are wider than the at least one slit in the top portion.

5. The cutting template of claim 1, wherein the at least one slit in the top portion and the openings in the bottom portion are in a pattern capable of forming a hemostatic patch having a shape comprising a star.

6. The cutting template of claim 1, wherein the at least one slit in the top portion and the openings in the bottom portion are in a pattern capable of forming a hemostatic patch having a shape comprising a rectangular patch possessing an elongated longitudinal slit extending from an edge of the patch and at least partially dividing the patch.

7. The cutting template of claim 1, wherein the at least one slit in the top portion and the openings in the bottom portion are in a pattern capable of forming a hemostatic patch having a shape comprising a rectangular patch possessing an elongated longitudinal slit extending from an edge of the patch and terminating at a circular opening within the patch.

8. The cutting template of claim 1, further comprising a handle.

9. A cutting template comprising:

a top portion possessing slits forming a star pattern;

a bottom portion possessing openings corresponding to the star pattern present in the top portion, the bottom portion further comprising a recessed region capable of holding a surgical patch therein; and

a means for connecting the top portion to the bottom portion.

10. The cutting template of claim 9, wherein the means for connecting the top portion to the bottom portion is selected from the group consisting of a catch, snap, hinge, interference fit, hinge, magnets, and combinations thereof.

11. The cutting template of claim 9, wherein the top portion and the bottom portion are connected to each other by a hinge.

12. The cutting template of claim 9, wherein the openings in the bottom portion are wider than the slits in the top portion.

13. The cutting template of claim 9, further comprising a handle.

14. A method comprising:

providing a cutting template comprising a top portion possessing at least one slit forming a desired pattern, a bottom portion possessing openings corresponding to the at least one slit present in the top portion, and a means for connecting the top portion to the bottom portion, the bottom portion further comprising a recessed region capable of holding a surgical patch therein;

introducing a surgical patch into the recessed region in the bottom portion;

passing a cutting device through the at least one slit in the top portion, the surgical patch, and the openings in the bottom portion, thereby cutting the surgical patch in the pattern of the at least one slit and openings;

removing the top portion of the template from the bottom portion of the template; and

removing the surgical patch possessing the pattern from the cutting template.

15. The method of claim 14, wherein the means for connecting the top portion to the bottom portion is selected from the group consisting of a catch, snap, hinge, interference fit, hinge, magnet, and combinations thereof.

16. The method of claim 14, wherein the top portion and the bottom portion are connected to each other by a hinge.

17. The method of claim 14, wherein the openings in the bottom portion are wider than the at least one slit in the top portion.

18. The method of claim 14, wherein the at least one slit in the top portion and the openings in the bottom portion are in a pattern capable of forming a hemostatic patch having a shape comprising a star.

19. The method of claim 14, wherein the at least one slit in the top portion and the openings in the bottom portion are in a pattern capable of forming a hemostatic patch having a shape comprising a rectangular patch possessing an elongated longitudinal slit extending from an edge of the patch and at least partially dividing the patch.

20. The method of claim 14, wherein the at least one slit in the top portion and the openings in the bottom portion are in a pattern capable of forming a hemostatic patch having a shape comprising a rectangular patch possessing an elongated longitudinal slit extending from an edge of the patch and terminating at a circular opening within the patch.
