Abstract:
1. A knotless suture anchor apparatus for anchoring a length of suture with respect thereto, comprising: an anchor body having a proximal end, a distal end, and a lumen opening at the proximal end such that a length of suture may be introduced into the lumen from the proximal end; and at least two series of a plurality of axially stacked suture-locking elements located within the anchor body lumen and each movable within the lumen from respective first positions to second positions, wherein the plurality of locking elements from both of the at least two series respectively overlie each other in an alternating configuration, and the locking elements in their first positions together defining a generally uniform cross-section axial passage sized to permit axial movement of the length of suture therethrough, and in their second positions converting the cross-section of the axial passage to be irregular and therefore substantially restrict axial movement of the length of suture therethrough.
