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.
Claims20
A device for treating an incision, hernia, or abdominal wall defect, comprising:
- an elongate element having a cross-section and a longitudinal axis perpendicular to the cross-section, the elongate element comprising an acellular tissue matrix rolled concentrically into a cylindrical structure extending along the longitudinal axis;
- a first sheet connected to the elongate element between a first end and a second end of the first sheet and extending along the longitudinal axis on a first side of the elongate element, the first sheet folding away from the elongate element to form a first portion and a second portion of the first sheet, the first and second portions of the first sheet forming a first opening therebetween;
- and
- a second sheet connected to the elongate element between a first end and a second end of the second sheet and extending along the longitudinal axis on a second side of the elongate element opposite to the first side, the second sheet folding away from the elongate element to form a first portion and a second portion of the second sheet, the first and second portions of the second sheet forming a second opening therebetween.

A method of closing a midline incision, comprising:
- providing an implant including (i) an elongate element having a cross-section and a longitudinal axis perpendicular to the cross-section, the elongate element comprising an acellular tissue matrix rolled concentrically into a cylindrical structure extending along the longitudinal axis, (ii) a first sheet connected to the elongate element between a first end and a second end of the first sheet and extending along the longitudinal axis on a first side of the elongate element, the first sheet folding away from the elongate element to form a first portion and a second portion of the first sheet, the first and second portions of the first sheet forming a first opening therebetween, and (iii) a second sheet connected to the elongate element between a first end and a second end of the second sheet and extending along the longitudinal axis on a second side of the elongate element opposite to the first side, the second sheet folding away from the elongate element to form a first portion and a second portion of the second sheet, the first and second portions of the second sheet forming a second opening therebetween;
- positioning the elongate element along the midline incision;
- and
- positioning a portion of a first rectus abdominus muscle in the first opening and positioning a portion of a second rectus abdominus muscle in the second opening such that the first portion of the first sheet covers an anterior portion of the first rectus abdominus muscle and the first portion of the second sheet covers an anterior portion of the second rectus abdominis muscle, and the second portion of the first sheet covers a posterior portion of the first rectus abdominus muscle and the second portion of the second sheet covers a posterior portion of the second rectus abdominis muscle.
