WEDGE PUSH-IN SUTURE ANCHOR
Methods and anchor devices for repairing soft tissue with a suture are provided. An anchor device comprises an elongate body having a proximal end, a distal end, and a first lumen extending from the proximal end, the first lumen having at least one face which is sloped relative to the central axis of the elongate body such that the cross-sectional area of the first lumen decreases in the proximal direction. The anchor device also comprises a suture locking wedge movably disposed at least partially within the first lumen.
1 . A method of securing a portion of tissue to a portion of bone using an anchor device, the method comprising:
inserting the anchor device into the portion of bone;
passing a repair suture around the portion of tissue;
shuttling the repair suture through the anchor device using a passing loop;
pulling the repair suture to a threshold amount of tension; and
removing an excess tail of the repair suture,
wherein the anchor device comprises:
an elongate body defining a lumen therethrough;
a suture having a first segment secured to the elongate body and a second segment disposed at least partially in the lumen, wherein the second segment extends from the first segment and enters to the lumen via a proximal portion of the elongate body; and
a wedge movably disposed within the lumen, the wedge configured to move away from the first segment, so as to transition from an unlocked position to a locked position, wherein transitioning the wedge to the locked position angularly moves at least a portion of the wedge relative to a longitudinal axis of the elongate body, to secure at least a portion of the second segment against an inner wall of the elongate body.
2 . The method of claim 1 , wherein the repair suture is passed through the portion of tissue.
3 . The method of claim 1 , wherein the passing loop comprises a suture material.
4 . The method of claim 1 , wherein the wedge has at least one cleat extending from a first side of the wedge that is contacts the suture in the locked position.
5 . The method of claim 1 , wherein an outer surface of the elongate body comprises a plurality of circumferential barbs or a plurality of grooves for fixation in bone.
6 . The method of claim 1 , wherein the channel runs parallel to the longitudinal axis which allows a proximal portion of the suture to translate.
7 . The method of claim 1 , further comprising a wedge lumen through the wedge spaced apart from a proximal tip thereof, wherein the wedge lumen is configured to allow the suture to pass therethrough.
8 . The method of claim 1 , wherein the lumen comprises a wedge ramp configured to angularly move the wedge when transitioning into the locked position.
