Abstract:
1. A method for knotlessly securing first and second tissues with a suture anchor comprising the steps of: forming a borehole in the first tissue; threading a suture through the second tissue forming a loop in the suture with the tissue thereby secured in the loop, the loop defining two suture portions; attaching the two suture portions to the anchor whereby the two suture portions are threaded through the anchor and initially movable with respect to the anchor; providing a force to a shaft of the anchor, the force causing clamping of the two suture portions in the anchor and deformation of a deformable portion of the anchor to cause the deformable portion to engage a wall of the borehole thereby to secure the suture anchor in the first tissue and the loop holding the second tissue to the suture anchor, further wherein the clamping comprises providing a spacing between two clamping members in the anchor wherein the two suture portions are received, moving the clamping members relatively with respect to each other to close the spacing and clamp the two suture portions between the clamping members, thereby frictionally engaging the two suture portions between the clamping members when the force is applied to the suture anchor; further comprising providing a convoluted path for the two suture portions in the anchor to assist in securement of the suture portions in the suture anchor; and further wherein the path is U-shaped.
