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 to a direction that the barb faces. The disposition of the barbs on the body can be staggered, twist cut multiple spiral, overlapping, or random. Also, the configuration of the barbs can be a certain spiral angle α, barb cut angle θ, barb cut depth, barb cut length, barb cut distance, corrugated barb underside, arcuate barb base, or varying barb size.
