Abstract
The present invention provides an apparatus for suture-based tissue repair, preferably for the annulus of a spinal disc, that includes a suture loop preferably pre-tied with a sliding knot, a clasp-type component that captures the ends of the suture loop, and an optional plug member that fills the tissue defect. Also disclosed is a method that places the suture loop in a full-thickness stitch encircling the tissue defect, secures the ends of the suture loop to the clasp, and cinches the suture loop to approximate the tissue without the need to tie knots. Also disclosed is a suture passer that enables a suture strand or loop to be passed through the tissue wall, captured, and retrieved. The suture passer may optionally incorporate a clasp in such an arrangement that enables a suture loop passed through the tissue wall to be captured directly by the clasp.
