Abstract

A method of improving the mechanical properties of a tissue patch is provided. The method includes the steps of providing a tissue patch and placing at least one barbed suture along at least a portion of the tissue patch. The method may further include the step of placing one or more additional barbed sutures in a laterally spaced relation to the barbed suture. The barbed suture may be biodegradable or non-biodegradable.

Claims

1. A reinforced tissue graft comprising:

a tissue patch; and

at least one barbed suture received within the tissue patch, wherein barbs of the at least one barbed suture are completely maintained within a thickness of the tissue patch, wherein the tissue patch is one of an allograft, a xenograft, or an autograft.

2. The reinforced tissue graft of claim 1, wherein the at least one barbed suture extends along a length of the tissue patch.

3. The reinforced tissue graft of claim 1, wherein the at least one barbed suture forms at least one of a Z-pattern or an X-pattern.

4. The reinforced tissue graft of claim 1, wherein the at least one barbed suture is in a spiral configuration.

5. The reinforced tissue graft of claim 1, wherein the at least one barbed suture is fixedly secured within the tissue patch.

6. The reinforced tissue graft of claim 1, wherein an entire length of the at least one barbed suture is completely maintained within the tissue patch.

7. The reinforced tissue graft of claim 1, wherein the at least one barbed suture includes a first barbed suture having a first diameter and a second barbed suture having a second diameter.

8. The reinforced tissue graft of claim 1, wherein the at least one barbed suture includes a first barbed suture having barbs extending in a first direction and a second barbed suture having barbs extending in a second direction.
