CONTINUOUS STITCH WOUND CLOSURE UTILIZING ONE-WAY SUTURE
First Claim
1. A method for closing a wound in skin of a subject by holding together first tissue on a first face of the wound and second tissue on a second face of the wound using a suture including an elongate body, a first end and a second end, and a first plurality of barbs projecting from a first portion of the elongate body between the first end of the suture and a second portion of the elongate body, the first plurality of barbs oriented to permit movement of the first portion of the elongate body through tissue toward the first end and prevent movement of the first portion of the elongate body through tissue in an opposite direction, the method comprising steps of:
- (a) inserting the first end of the suture into the first tissue at a first entrance point on the first face of the wound;
(b) pushing the first end of the suture through the first tissue until the first end of the suture extends out of the first tissue at a first exit point below the skin on the first face of the wound;
(c) gripping the first end of the suture and drawing the first portion of the elongate body through the first tissue until the second portion of the elongate body is adjacent the first entrance point thereby leaving a length of the first portion of the elongate body in the first tissue between the first entrance point and the first exit point;
(d) inserting the first end of the suture into the second tissue at a second entrance point below the skin on the second face of the wound;
(e) pushing the first end of the suture through the second tissue until the first end of the suture extends out of the second tissue at a second exit point below the skin on the second face of the wound;
(f) gripping the first end of the suture and drawing the first portion of the elongate body through the second tissue leaving a length of the first portion of the elongate body in the second tissue between the second entrance point and the second exit point; and
(g) securing the second portion of the elongate body to a tissue.

Abstract
Continuous wound-closure techniques use one-way suture. The one-way suture has tissue-grasping surface features which allow passage of the suture in one direction through tissue, but not in the opposite direction. In closing a wound, the one-way suture is passed alternately through tissue on opposed sides of the wound. The wound-closure techniques allow approximation of the sides of the wound without knots, avoid loop stitching and reduce scarring.

9. A method for joining a first tissue portion of a tissue and a second tissue portion of the tissue, the method using a suture including an elongate body, a first end and a second end, and a first plurality of projections distributed on a first portion of the elongate body between the first end of the suture and a second portion of the elongate body, the first plurality of projections oriented to permit movement of the first portion of the elongate body through tissue toward the first end and prevent movement of the first portion of the elongate body through tissue in an opposite direction, the method comprising steps of:
-
(a) inserting the first end of the suture into a first entrance point in the first tissue portion; (b) pushing the first end of the suture through the first tissue portion until the first end of the suture extends from a first exit point in the first tissue portion longitudinally spaced from the first entrance point in the first tissue portion; (c) gripping the first end of the suture and pulling the first end out of the first tissue portion and drawing the first portion of the elongate body through the first tissue portion until the second portion of the elongate body is adjacent the first entrance point in the first tissue portion, leaving a length of the first portion of the suture in the first tissue portion; (d) inserting the first end of the suture into a second entrance point in the second tissue portion; and (e) pushing the first end of the suture through the second tissue portion along a curvilinear path until the first end of the suture extends from a second exit point in the second tissue portion longitudinally spaced from the second entrance point in the second tissue portion. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method for approximating a first side and a second side of a wound, the method comprising:
-
(a) receiving a wound-closure device including a strand of bio-absorbable polymer suture thread, the strand having a first end and a second end, a curved needle secured to the first end of the strand, a first strand portion adjacent the first end, a second strand portion adjacent the second end, a plurality of projections distributed on the first strand portion, the plurality of projections being oriented to permit movement of the first strand portion body through tissue in a direction of the curved needle and grasp tissue in an opposite direction; (b) passing the curved needle through a first curved subcutaneous path in tissue of the first side and drawing the first strand portion along the first curved subcutaneous path leaving a part of the first strand portion on the first curved subcutaneous path in tissue of the first side; (c) passing the curved needle through a second curved subcutaneous path in tissue of the second side and drawing the first strand portion along the second curved subcutaneous path leaving a part of the first strand portion on the second curved subcutaneous path in tissue of the second side; and (d) approximating at least a portion of the first side and the second side of the wound. - View Dependent Claims (16, 17, 18, 19, 20)
