Abstract

Provided herein are sutures to be used in a procedure applied to tissue, and methods for forming such sutures. A suture can include an elongated suture body and a plurality of heat-contact mediated retainers extending from and along the elongated suture body. The heat-contact mediated retainers can be formed by temporarily contacting the elongated suture body with one or more heated element.

Claims (5)

1. A suture that can be used during a procedure applied to tissue, comprising: an elongated suture body; and a plurality of heat-contact mediated retainers arranged along at least a portion of the elongated suture body and extending outward from the elongated suture body, wherein the elongated suture body includes a first longitudinal portions; and a first group of the heat-contact mediated retainers extend from the first longitudinal portion substantially yield to motion of the elongated suture body within the tissue when the elongated suture body is drawn in a first direction and resist motion of the elongated suture body in a second direction opposite the first direction.

2. The suture of claim 1 , wherein the heat-contact mediated retainers are formed of heated and reformed portions of the elongated suture body.

3. The suture of claim 1 , wherein the heat-contact mediated retainers are treated to increase their stiffness and strength.

4. The suture of claim 1 , wherein: the elongated suture body further includes a second longitudinal portion; and a second group of the heat-contact mediated retainers extend from the second longitudinal portion and substantially yield to motion of the elongated suture body within the tissue when the elongated suture body is drawn in the second direction and resist motion of the elongated suture body in the first direction.

5. The suture of claim 1 , wherein each heat-contact mediated retainer comprises a retainer body projecting from the elongated suture body and a retainer end adapted to penetrate tissue.
