A wound closure device having a filamentary element having a proximal end and a distal end, and a stop element 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.

Barbed suture having increased holding strength

A surgical suture includes an elongated core having a first leg and a second leg, a first set of barbs projecting from the first leg of the core, and a second set of barbs projecting from the second leg of the core. The suture has a stop projecting from the core that is located between the first and second sets of barbs, and a braid surrounding the elongated core and the stop for strengthening the suture. The suture includes a pledget having first and second openings extending through the pledget, with the first leg extending through the first pledget opening, the second leg extending through the second pledget opening, and the stop extending between the first and second pledget openings.

Barbed sutures having pledget stoppers and methods therefor

Surgical needles are described which exhibit a tapered region intermediate the point and barrel sections, over which the needles undergo a gradual transition in shape from a generally rounded circumference to a rectangular I-beam shape. The I-beam shape affords favorable strength characteristics and the gradual transition in shape smoothes the changes in penetration force performance.
