Abstract:
1. A system for repairing a meniscus comprising: a suture including a first anchor, a second anchor, and a flexible portion connecting the first anchor and the second anchor, the flexible portion including a self-locking slide knot between the first anchor and the second anchor; a needle having a longitudinal extending bore, an open end, and a cutting surface at the open end for cutting the flexible portion of the suture, the bore being configured to receive the first anchor and the second anchor; a body portion operatively connected to the needle at a distal end of the body portion, the body portion having a lumen; a pusher configured to slide and rotate within the lumen of the body portion and the longitudinal bore of the needle, the pusher having a first stop surface, a second stop surface, and a hollow rod with a pair of slots, the slots being configured to expose a portion of the flexible portion of the suture so that when the exposed portion is aligned with the cutting surface, the exposed portion is cut against the cutting surface when the pusher is moved relative to the cutting surface, the first stop surface of the pusher being constructed and arranged to engage a proximal end of the body portion after the first anchor has been discharged from the needle by the pusher to prevent the pusher from discharging the second anchor, and the second stop surface of the pusher being constructed and arranged to engage the proximal end of the body portion after the second anchor has been discharged from the needle by the pusher.
