1. A method of securing soft tissue with respect to a body cavity without knots, comprising:
- passing a length of suture through soft tissue so that a portion of the suture is secured in the soft tissue resulting in at least one free end;
providing an anchor comprising an anchor body having a lumen extending therethrough, and a locking plug having a shaft portion extending at least partially in the anchor body lumen;
the anchor body is non-deformable and where inserting the anchor body into the cavity comprises partially deforming the wall of the body cavity;
the anchor body is generally tubular and has a plurality of tapered ridges circumferentially located about the anchor body and permit insertion of the anchor body into the body cavity when advanced in a first direction and resist removal of the anchor body when withdrawn in an opposite direction;
passing the free end of the suture into the anchor such that a first section of the suture is in a portion of the locking plug and extends through the anchor body lumen;
applying tension to the suture between the tissue and the anchor; and
inserting the anchor into the body cavity, such that a second section of the suture is between the anchor body and a wall of the body cavity.

Abstract
An innovative bone anchor and methods for securing soft tissue, such as tendons, to bone are described herein. Such devices and methods permit a suture attachment that lies beneath the cortical bone surface and does not require tying of knots in the suture.

17. A method for knotless securing of soft tissue to hard tissue, the method comprising:
-
providing an anchor having an anchor body and a locking plug, where the locking plug is moveable through a lumen of the anchor body until a stop of the locking plug contacts the anchor body;
the anchor body is non-deformable and where inserting the anchor body into the cavity comprises partially deforming the wall of the body cavity;
the anchor body is generally tubular and has a plurality of tapered ridges circumferentially located about the anchor body and permit insertion of the anchor body into the body cavity when advanced in a first direction and resist removal of the anchor body when withdrawn in an opposite direction;securing a suture to the soft tissue; advancing a first section of the suture through the stop and through the body lumen; tensioning a portion of the suture; and securing the anchor into a cavity formed in the hard tissue, such that the first section of the suture is compressed between the anchor body and the locking plug and a second section of the suture is compressed between a wall of the cavity and an exterior of the anchor body. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26)
