Abstract:
1. A method for securing soft tissue to bone comprising: (a) securing a first limb of a length of suture to the soft tissue to be attached to the bone; (b) extending the length of suture into an anchor body and looping the length of suture around a suture locking member movably disposed within the anchor body and such that a second limb of the suture extends from the anchor body, the suture locking member being cooperatively engaged with the anchor body to move between an unlocked position in which the length of suture slides around the suture locking member, and a locked position in which the length of suture is compressed between a first contact surface of the suture locking member and the anchor body, wherein the suture locking member has an elongate cross section, angled towards a more parallel orientation relative to an elongate axis of the anchor body while in the unlocked position so as to provide a larger gap between the first contact surface and the anchor body and ease the steps of extending and looping; (c) fixing the anchor body within the bone; (d) applying a first tension on the second limb of the length of suture such that the length of suture slides around the suture locking member so as to move the first limb of the suture and the soft tissue towards the anchor body and until a second tension on the first limb of the suture arises from the soft tissue; and (e) releasing the second limb, thereby halting the application of the first tension on the second limb such that the second tension on the first limb of the suture causes the suture locking member to rotate and translate from the unlocked position to the locked position, thereby compressing the length of suture between the suture locking member and the anchor body.
