The device comprises anchor having a front section and a rear section, a cannula extending through the front and rear sections through which the suture extends, and a bead positioned adjacent an end of the suture for locking the suture within the cannula.

Independent Claims | See all claims (11)

  1. 1. A device for locking a suture in place, comprising: an anchor having a cannula through which the suture extends, the anchor further comprising a rear edge and a front edge; and a locking mechanism for locking the suture within the cannula; wherein the suture comprises a first end and a second end, the suture extending through the cannula of the anchor from the rear edge of the anchor to the front edge of the anchor, the suture adapted to pass through a portion of tissue and extend back through the cannula from the front edge to the rear edge; wherein the locking mechanism comprises a bead formed at the first end of the suture, the bead sized to wedge within the cannula to lock the first end and the second end of the suture in the cannula.
  2. 7. A device for locking a suture in place, comprising: an anchor having a cannula through which the suture extends, the anchor further comprising a rear edge and a front edge; the suture having a first end and a second end, the suture extending through the cannula of the anchor from the rear edge of the anchor to the front edge of the anchor, the suture adapted to pass through a portion of tissue and extend back through the cannula from the front edge to the rear edge; and a bead fixed to the suture adjacent the first end, the bead sized to wedge within the cannula and lock the first and second ends in place.
