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 an overlapping disposition such that for at least two adjacent barbs, one being an overlapping barb and one being an overlapped barb, the overlapping barb has an underside (US) and the overlapped barb has a topside (TS) where part of the underside (US) of the overlapping barb is derived from part of and the topside (TS) of the overlapped barb.
