Barbed suture that connects a human or animal to a surgical needle. The suture includes an elongated body and a plurality of barbs protruding from the body. Each barb inhibits suture movement in the opposite direction that the barbs face. The arrangement of the barbs on the body may be zigzag, twisted multiple helix, overlapping or irregular. In addition, the model of the barbs may be a particular helix angle α, barb cutting angle θ, barb cutting depth, barb cutting length, barb cutting distance, corrugated barb lower side, arcuate barb base or varying barb size. |
