Abstract

Devices and methods for treating an abdominal incision or hernia are described. An implant for the restoration or prophylactic treatment of an abdominal wall comprises an elongate element and at least one sheet connected to the elongate element along a longitudinal axis of the elongate element. The elongate element is positioned along the line of incision, and the at least one sheet is secured to the abdominal muscles surrounding the incision.

Claims (19)

1. A method of closing a midline incision, comprising the steps of:

providing an implant comprising an a cylindrical elongate element having a first longitudinal axis and at least one sheet connected to the elongate element along the first longitudinal axis, wherein the cylindrical elongate element comprises an acellular tissue matrix concentrically rolled into a cylindrical structure;

positioning the elongate element along the midline incision; and

positioning the at least one sheet on at least one of an anterior side and a posterior side of a rectus abdominis muscle surrounding the midline incision.

2. The method of claim 1 , further comprising the step of creating spaces on the anterior and/or posterior sides of the rectus abdominis muscle for placement of the at least one sheet.

3. The method of claim 1 , further comprising the step of suturing the at least one sheet to the rectus abdominis muscle.

4. The method of claim 3 , wherein the sutures comprise loop sutures that incorporate the elongate element.

5. The method of claim 1 , wherein the at least one sheet is inserted between an anterior layer of fascia and the rectus abdominis muscle.

6. The method of claim 1 , wherein the at least one sheet is inserted between a posterior layer of fascia and the rectus abdominis muscle.

7. The method of claim 1 , wherein the at least one sheet is inserted over an anterior layer of fascia.

8. The method of claim 1 , wherein the at least one sheet is inserted below a posterior layer of fascia.

9. The method of claim 1 , wherein the at least one sheet comprises an acellular dermal matrix.

10. The method of claim 9 , wherein the acellular dermal matrix is treated to remove antigens that are immunogenic to a human recipient.

11. The method of claim 1 , wherein the at least one sheet is connected to the elongate element along a line substantially parallel to the first longitudinal axis.

12. The method of claim 11 , wherein the at least one sheet is folded along the line substantially parallel to the first longitudinal axis to form a pocket .

13. The method of claim 12 , wherein the rectus abdominis muscle surrounding the incision is positioned in the pocket.

14. The method of claim 1 , wherein the acellular tissue matrix is thicker than the at least one sheet.

15. The method of claim 1 , wherein the elongate element has a strength that is at least equal to that of the at least one sheet.

16. The method of claim 1 , wherein the elongate element has a strength that is greater than that of the at least one sheet.
