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. ## Claims ### Claim 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. ### Claim 2 (depends on 1) The implantable abdominal hernia repair mesh of claim 1, further comprising a fixation device at the second end of each mesh extension. ### Claim 3 (depends on 2) 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. ### Claim 4 (depends on 1) 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. ### Claim 5 (depends on 1) The implantable abdominal hernia repair mesh of claim 1, wherein the mesh body and the mesh extensions are fabricated as a uniform mesh construction. ### Claim 6 (depends on 1) 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. ### Claim 7 (depends on 1) 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. ### Claim 8 (depends on 1) The implantable abdominal hernia repair mesh of claim 1, wherein the length of the mesh extensions is between 10 cm and 90 cm. ### Claim 9 (depends on 1) 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. ### Claim 10 (depends on 1) The implantable abdominal hernia repair mesh of claim 1, wherein each mesh extension is 0.2-3 cm wide. ### Claim 11 (depends on 1) 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. ### Claim 12 (depends on 1) The implantable abdominal hernia repair mesh of claim 1, wherein the length of the mesh extensions is between 2 cm and 150 cm. ### Claim 13 (depends on 1) The implantable abdominal hernia repair mesh of claim 1, wherein the length of the mesh extensions is at least 10 cm. ### Claim 14 (depends on 1) The implantable abdominal hernia repair mesh of claim 1, wherein the implanted mesh can withstand at least 16 N/cm without dehiscing or migrating. ### Claim 15 (depends on 1) 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. ### Claim 16 (depends on 15) 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. ### Claim 17 (depends on 1) 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. ### Claim 18 (depends on 17) 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. ### Claim 19 (depends on 18) 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. ### Claim 20 (depends on 1) 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. ### Claim 21 (depends on 1) 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.
