Barb configurations for barbed sutures
First Claim
1. A barbed suture for connecting human or animal tissue, said suture comprising (a) an elongated body having a longitudinal axis, a first end, and a second end (b) a plurality of barbs projecting from the body each barb facing in a direction and being adapted for resisting movement of the suture, when in tissue, in an opposite direction from the direction in which the barb faces, wherein the barbs have an underside, and the underside of the barb attaches to the suture body along a line that is transverse to the longitudinal axis of the elongated body and is concave arcuate, and a barb cut angle Θ
- ranging from about 140 degrees to about 175 degrees.

Abstract
A barbed suture for connecting tissue, and a combination surgical needle with a barbed suture. 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 may be staggered, twist cut multiple spiral, overlapping, or random. Also, the configuration of the barbs may be a certain spirality 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.
