  • Publication number: 20030153976
    Abstract: A spinal disc annulus repair stent for repair and reconstruction of the spinal disc wall (annulus) after surgical invasion or pathologic rupture, which may incorporate suture closure or other means of stent insertion and fixation, designed to reduce the failure rate of conventional surgical procedures on the spinal discs. In an illustrative embodiment, the design of the spinal disc annulus stent advantageously allows ingrowth of normal cells of healing in an enhanced fashion strengthening the normal reparative process.
