Abstract
The embodiments provided for herein relate to apparatus and methods for securing tissue to bone using a suture anchoring system that provides enhanced tactile feedback and does not require tying a suture knot. In each embodiment, a surgeon can individually tension the free ends of the suture to fine-tune the placement of the tissue with respect to the bone, and then secure the suture without tying a knot. In several embodiments, the device may be transformed between locked and unlocked suture states, thereby allowing further fine-tuning of the tension in the suture. In other embodiments, the device may permit unidirectional movement of a suture, while preventing slippage or movement of the suture and tissue in the opposite direction.

20. A method of coupling a tissue to a bone comprising:
-
positioning a bone anchor in an opening in a bone, the bone anchor comprising;
a body, the body comprising a cavity having a proximal end, a distal end, one or more side surfaces, an opening at the proximal end, and an inner surface at the distal end of the cavity;
a cam pivotally coupled to the body and positioned at least partially in the cavity, wherein the cam is configured to pivot between a first position and a second position; and
a suture length positioned in the space between the cam and the inner surface at the distal end of the cavity; and
coupling at least a portion of the suture to a tissue. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)
