Abstract
A toggle-type suture anchor that incorporates individual suture tensioning and locking without knot tying. The anchor includes an elongate toggle body having a working suture pre-threaded into a first passage and back up and out a second passage with a length running longitudinally adjacent the side of the anchor. A locking suture loop is pre-threaded into a third passage between the first and second passage and includes a collapsible loop that encircles a portion of the length of suture running longitudinally adjacent the side of the anchor. With the loop open, the working suture can slide through the anchor, however, when the loop is closed the working suture is locked in position to retain tension on the working suture. The anchor can be utilized in a pre-strung connected array of anchors.
