1. A method for anchoring suture to bone, comprising:
- coupling a suture to a suture anchor such that the suture extends around a suture-engaging feature of the suture anchor and trailing ends of the suture extend through an inner lumen extending through the suture anchor and out of a proximal end of the suture anchor, the inner lumen having a driver-receiving portion formed therein, the driver-receiving portion extending along a substantial longitudinal length of the suture anchor, the suture anchor including a constant diameter portion extending along a partial longitudinal length of the suture anchor, and the suture anchor including a pointed, tapering distal tip extending distally from the constant diameter portion, the suture anchor having only one cut-out formed through a sidewall thereof, and the one cut-out being located entirely in the constant diameter portion proximal to the tapering distal tip;
inserting a driver into the inner lumen such that a distal end of the driver engages a distal end of the driver-receiving portion; and
rotating the driver to thread the suture anchor into bone to secure the suture to the bone.

Abstract
Methods and devices are provided for anchoring suture to bone. In one exemplary embodiment, a cannulated suture anchor is provided and it includes a suture-engaging member formed therein and configured to receive a suture therearound such that trailing ends of the suture can extend through the suture anchor. The suture anchor can also include at least a proximal portion having dual threads to facilitate engagement with bone. The present invention also provides exemplary sutures and drivers that can be used with the various methods and devices disclosed herein, or with other methods and devices known in the art.

14. A method for anchoring suture to bone, comprising:
-
coupling a suture to a suture anchor such that the suture extends around a suture-engaging feature of the suture anchor and trailing ends of the suture extend through an inner lumen extending through the suture anchor and out of a proximal end of the suture anchor, the suture-engaging feature being at a fixed axial position relative to the suture anchor, the inner lumen having a driver receiving portion formed therein, the driver-receiving portion extending along a substantial longitudinal length of the suture anchor, the suture anchor including a constant diameter portion extending along a partial longitudinal length of the suture anchor, and the suture anchor including a pointed, tapering distal tip extending distally from the constant diameter portion, the suture anchor having a cut-out formed through a sidewall thereof, a proximal-most end of the cut-out being proximal to the suture-engaging feature, a distal-most end of the cut-out being distal to the suture engaging feature, and the cut-out being located entirely in the constant diameter portion proximal to the tapering distal tip; inserting a driver into the inner lumen such that a distal end of the driver engages a distal end of the driver-receiving portion; and rotating the driver to thread the suture anchor into bone to secure the suture to the bone. - View Dependent Claims (15)
