THREADABLE KNOT SOFT TISSUE DEFECT REPAIR SYSTEM

摘要

A soft tissue defect repair system for approximating defects, such as defects in the annulus fibrosus of an intervertebral disc, includes a cannulated rod through which is disposed a suture retrieval device. A strand of suture includes a locking or ratcheting knot pre-tied around the outside of the cannulated rod and a free end that is guided in and out of the soft tissue. A knot pusher fits around the cannulated rod, which is used to pushthe knot off of the cannulated rod after the stitching of the tissue is accomplished. The defect is approximated by tensioning the free end. Various suturing methods or patterns are disclosed for defect approximation.
