Abstract
Systems, apparatuses and methods for securing tissue to bone using a bone anchoring system are described. Methods and apparatuses may allow transformation between locked and unlocked states, thereby allowing adjustment of the tension in the suture. The apparatus and/or methods may allow unidirectional movement of a suture, while preventing slippage or movement of the suture and tissue in the opposite direction. Ends of a suture may be individually tensioned to adjust positioning of a tissue with respect to a bone.

32. A method of coupling a tissue structure to bone comprising:
-
coupling a suture to a tissue; coupling at least one end portion of the suture to the locking assembly; positioning a bone anchor in an opening in a bone, the bone anchor comprising; a main body configured to be placed in an opening in a bone, the main body comprising a proximal end, a distal end, and a cavity, the cavity comprising an opening at or near the proximal end; and a two bar locking assembly at least partially disposed in the cavity of the bone anchor main body, the two bar locking assembly comprising at least two interacting locking elements, wherein at least two of the interacting locking elements comprises at least one bar; and positioning the locking elements, with respect to each other, such that the bars of the locking elements allow movement of the suture in a first direction and inhibit movement of the suture in a direction opposite to the first direction. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)
