Abstract
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.
Claims17
An anchor device for repairing soft tissue with a suture, the anchor device comprising:
- an elongate body having a proximal end, a distal end, a first lumen extending from the proximal end, a first lateral opening, and a second lateral opening located distal to the first lateral opening and on the same side of the elongate body as the first lateral opening, the first lumen having a sloped region defined by at least one face which is sloped relative to a longitudinal axis of the elongate body, such that the cross-sectional area of the first lumen decreases along the sloped region in a proximal direction;
- a suture locking wedge movably disposed at least partially within the first lumen;
- and
- a suture located at least partially in the first lumen of the elongate body between a first side of the suture locking wedge and an internal face of the elongate body opposite the sloped region, and wherein the suture is configured to pass through the first lateral opening in the elongate body to contact an exterior surface of the elongate body;
- wherein the suture locking wedge is configured to move from a distal unlocked position in which the suture is able to slide through the anchor body and optionally the suture locking wedge, to a proximal locked position in which the suture is compressed in the first lumen by the first side of the suture locking wedge and the elongate body as a result of the face of the sloped region being in contact with a second side of the suture locking wedge;
- wherein the first lateral opening and the second lateral opening are distal to the suture locking wedge when the suture locking wedge is in the proximal locked position.
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 having a proximal end, a distal end, a first lumen extending from the proximal end, and a first lateral opening, the first lumen having a sloped region defined by at least one face which is sloped relative to a longitudinal axis of the elongate body, such that the cross-sectional area of the first lumen decreases along the sloped region in a proximal direction;
- and
- a suture locking wedge movably disposed at least partially within the first lumen;
- wherein the repair suture is located at least partially in the first lumen of the elongate body between a first side of the suture locking wedge and an internal face of the elongate body opposite the sloped region, and wherein the repair suture is configured to pass through the first lateral opening in the elongate body to contact an exterior surface of the elongate body,
- wherein the suture locking wedge is configured to move from a distal unlocked position in which the repair suture is able to slide through the anchor body and optionally the suture locking wedge, to a proximal locked position in which the repair suture is compressed in the first lumen by the first side of the suture locking wedge and the elongate body as a result of the face of the sloped region being in contact with a second side of the suture locking wedge;
- wherein the first lateral opening is distal to the suture locking wedge when the suture locking wedge is in the proximal locked position.
