Barbed sutures

摘要

A barbed suture for connecting tissue. The suture includes an elongated body and a plurality of barbs projecting from the body. Each barb causes the suture to resist movement in an opposite direction from which the barb faces. The disposition of the barbs on the body is a staggered disposition such that the barbed suture has at least two sets of barbs that are offset with respect to each other, each set being aligned longitudinally on the barbed suture, where each barb has a base, and a plane perpendicular to the barbed suture and cutting transversely through the barbed suture and intersecting the base of a barb of the first set will not intersect the base of a barb of the second set.
