Implantable mesh and method of use
An implantable mesh for use in reconstructing tissue includes a mesh body and one or more extensions extending from the mesh body. Each mesh extension has a first end and a second end, wherein the first end of the mesh extension is integrated into or part of the mesh body. Each mesh extension is configured to permit multiple anchor points with surrounding tissue upon implantation. In one embodiment, a fixation device is at the second end of each mesh extension. Methods of using the implantable mesh are also provided.
1. An implantable abdominal hernia repair mesh for use in reconstructing herniated abdominal tissue, the implantable abdominal hernia repair mesh comprising:
a mesh body having a surrounding edge;
mesh extensions arranged in opposing pairs extending oppositely from the surrounding edge of the mesh body, each mesh extension is comprised of mesh and has a first end, a second end, and a length therebetween, the first end being integrated into or part of the mesh body; and
wherein each mesh extension is configured to be passed through surrounding tissue multiple times on opposite sides of the herniated abdominal tissue to permit multiple anchor points with the surrounding tissue upon implantation so as to resist high tension across an abdominal hernia repair site without dehiscing or migrating.
2. The implantable abdominal hernia repair mesh of claim 1 , further comprising a fixation device at the second end of each mesh extension.
3. The implantable abdominal hernia repair mesh of claim 2 , wherein a fixation device is selected from the group consisting of a surgical needle permanently connected to the second end of each mesh extension, a device permanently connected to the second end of each mesh extension and a tack.
4. The implantable abdominal hernia repair mesh of claim 1 , comprising two or more mesh extensions extending from the surrounding edge of the mesh body, and wherein at least two of the mesh extensions extend from the surrounding edge in opposite directions from one another.
5. The implantable abdominal hernia repair mesh of claim 1 , wherein the mesh body and the mesh extensions are fabricated as a uniform mesh construction.
6. The implantable abdominal hernia repair mesh of claim 1 , wherein the mesh body is comprised of mesh threads woven or knitted together, and each mesh extension is formed by the mesh threads.
7. The implantable abdominal hernia repair mesh of claim 1 , wherein each mesh extension is initially separate from the mesh body and is comprised of mesh threads woven or knitted together, wherein the mesh extensions are integrated into the mesh body by weaving the mesh threads of the mesh extension into the mesh body.
8. The implantable abdominal hernia repair mesh of claim 1 , wherein the length of the mesh extensions is between 10 cm and 90 cm.
9. The implantable abdominal hernia repair mesh of claim 1 , wherein at least two mesh extensions are spaced apart from one another by an amount between 1 mm and 100 cm.
10. The implantable abdominal hernia repair mesh of claim 1 , wherein each mesh extension is 0.2-3 cm wide.
11. The implantable abdominal hernia repair mesh of claim 1 , wherein at least one of the mesh body and each mesh extension is comprised of synthetic material or a biological material.
12. The implantable abdominal hernia repair mesh of claim 1 , wherein the length of the mesh extensions is between 2 cm and 150 cm.
13. The implantable abdominal hernia repair mesh of claim 1 , wherein the length of the mesh extensions is at least 10 cm.
14. The implantable abdominal hernia repair mesh of claim 1 , wherein the implanted mesh can withstand at least 16 N/cm without dehiscing or migrating.
15. The implantable abdominal hernia repair mesh of claim 1 , wherein each mesh extension comprised of mesh is configured to be woven through surrounding tissue at least three times.
16. The implantable abdominal hernia repair mesh of claim 15 , wherein each mesh extension comprised of mesh is configured to be woven through tissue with at least three throws of a running x weave pattern, a locking x weave pattern, a continuous locking weave pattern, or a linear parallel weave pattern.
17. The implantable abdominal hernia repair mesh of claim 1 , further comprising at least four mesh extensions comprised of mesh positioned to form at least two laterally opposing pairs.
18. The implantable abdominal hernia repair mesh of claim 17 , wherein all of the mesh extensions comprised of mesh extend from one of two opposing edges of the mesh body.
19. The implantable abdominal hernia repair mesh of claim 18 , further comprising at least six mesh extensions comprised of mesh, wherein all of the mesh extensions are configured in opposing pairs.
20. The implantable abdominal hernia repair mesh of claim 1 , further comprising at least six mesh extensions comprised of mesh, wherein at least three mesh extensions extend from each of two opposing edges of the mesh body.
21. The implantable abdominal hernia repair mesh of claim 1 , wherein the implanted mesh is configured to resist tension across the abdominal hernia repair site of least 16 newtons per centimeter without dehiscing or migrating from the abdominal hernia repair site.
