BARBED SUTURE HAVING INCREASED HOLDING STRENGTH

摘要

A wound closure device (100) having a filamentary element (102) having a proximal end (109) and a distal end (106), and a stop element (108) coupled thereto and having a leading edge area defined by thickness and a width and having a total surface area. The leading edge area is substantially perpendicular to a longitudinal axis of the filamentary element. The device may have a ratio of the leading edge area to the total surface area that is less than 10%, a ratio of the length to the maximum thickness of the stop element that is at least 4, or a ratio of the length to the width of the stop element is at least 1 for any given thickness.
