Abstract
An embodiment of a suture for use in a surgical procedure applied to tissue comprises an elongated body having a first end and a second end, and a plurality of retainers arranged along a portion of the elongated body. The retainers substantially yield to motion of the elongated body within the tissue when the elongated body is drawn at the first end and resist motion of the elongated within the tissue when the elongated body is drawn at the second end. The retainers include an upper surface and a lower surface, the upper surface extending from a periphery of the elongated body and the lower surface having at least two facets.
