1. An anchor device for repairing soft tissue with a suture, comprising:
- an anchor body comprising a wall, and the wall defining a lumen; and
a suture locking wedge movably disposed within the lumen and engaged with the wall of the anchor body such that the suture locking wedge may move with a first degree of freedom and a second degree of freedom with respect to the lumen and such that when a first tension force is applied to a tissue limb of the suture extending through the anchor body and looped around the suture locking wedge, the suture locking wedge is urged into a suture locking position in which the suture is compressed between the suture locking wedge and a first contact location of the anchor body; and
wherein the suture locking wedge has an elongate cross section that is moved from a more parallel orientation towards a more perpendicular orientation relative to an elongate axis of the anchor body when urged to the suture locking position.

Abstract
A suture anchor device and method for attaching soft tissue to bone includes an anchor body and a suture locking wedge movably disposed within the anchor body. The suture locking wedge includes lateral portions which engage slots or windows in the anchor body. Tension applied to one limb of a suture causes the suture locking wedge to translate and rotate to a position which compresses the suture, thereby locking the suture in the anchor.

13. An anchor device for repairing soft tissue with a suture, the anchor device comprising:
-
an anchor body comprising an inner wall wherein the inner wall defines a lumen, and said inner wall further defines at least one window; and a suture locking wedge rotatably and translatably movable within the lumen and engaged with the at least one window of the anchor body such that the suture locking wedge is movable between a first position and a second position, and such that when a tension force is applied to a tissue limb of the suture extending through the anchor body and looped around the suture locking wedge, the suture locking wedge is urged into the first position in which the suture is compressed between the suture locking wedge and a first contact location of the anchor body; and
wherein the suture locking wedge has an elongate cross section defining an approximately uniform width and an elongate cross section axis that is moved from a more parallel orientation towards a more perpendicular orientation relative to an elongate axis of the anchor body when urged to the first position. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
