Patent number: 8137383Abstract: A method for securing first and second tissues with a suture anchor. The steps include 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; and 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.Type: GrantFiled: October 27, 2010Date of Patent: March 20, 2012Assignee: Linvatec CorporationInventors: Hugh Sloan West, Jr., Lehmann K.
