Abstract

A suture-locking apparatus comprising a body member having a proximal end, a distal end, and an axial lumen in between the proximal and distal ends, wherein the proximal end adapted for passing a portion of a suture into the lumen; and a plug member movable from a first position to a second position in the lumen, the plug member comprising a radial protrusion adapted for compressing the suture against the body member on moving to the second position. In a further embodiment the invention is a method of anchoring soft tissue in a body cavity with a suture using the present apparatus and without tying a knot.

Description

[0001] This application is a Continuation-in-part of commonly assigned U.S. patent application Ser. No. 09 / 781,793, filed on Feb. 12, 2001, which is herein incorporated by reference in its entirety.BACKGROUND

[0002] 1. Field of the Invention

[0003] This invention relates generally to apparatus and methods for attaching soft tissue to bone, and more particularly to a knotless suture-locking apparatus comprising a radial protrusion on a suture plug for securing a suture and for restricting the movement of the plug in the apparatus such that the plug will not be dislodged when the suture is subjected to loading after the procedure is completed. The invention has particular application to arthroscopic surgical techniques for anchoring the rotator cuff in the humeral head in repairing the rotator cuff.

[0004] 2. Prior Art

[0005] It is an increasingly common problem for tendons and other soft, connective tissues to tear or to detach from associated bone. One such type of tear or detachment...
