Abstract

A barbed suture with a first end and a second end and a body with a plurality of barbs extending from the body. Each barb causes the suture to resist movement in an opposite direction from which the barb faces. Projections extend from said suture. The projections can also engage tissue. The barbs cover the projections when the first end of the suture is moved in tissue and exposes the projections in order to engage tissue when the suture is moved in the direction of the second end through tissue.
