Dual thread cannulated suture anchor
First Claim
Patent Images
1. A suture anchor, comprising:
- an elongate body having first and second threads extending from a proximal end toward a distal end of the elongate body, an inner lumen extending into thea proximal end of the elongate body, and a cut-out formed through a sidewall of the elongate body and in communication with the inner lumen,wherein the cut-out defines a suture-engaging member extending across the inner lumen and configured such that a suture can extend around the suture-engaging member and trailing ends of the suture can extend through the elongate body,wherein the cut-out defines opposed arms that extend distally from the suture-engaging member, andwherein the first and second threads terminate proximal to a proximal-most end of the cut-out.

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.

7. A suture anchor, comprising:
a unitary cannulated body having a non-threaded distal portion, a threaded proximal portion with first and second threads extending from a proximal end toward a distal end of the cannulated body, an opening formed in a sidewall of the cannulated body in the non-threaded distal portion thereof, and a suture-engaging member in the non-threaded distal portion extending across an inner lumen extending through the elongate body, the suture-engaging member configured such that a suture can extend around the suture-engaging member and trailing ends of the suture can extend through the cannulated body, wherein the opening defines opposed arms spaced a distance apart from one another, the arms extending distally from the suture-engaging member. - View Dependent Claims (8, 9, 10, 11)
