  • Patent number: 7846208
    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.

  • Publication number: 20090131978
    Abstract: A release assembly is provided to aid the reversible and repositionable deployment of a defect occluder. The release assembly includes an occluder tether having a distal portion comprising at least one suture loop, and a snare structure having a distal portion comprising a snare element. The at least one suture loop is receivable through at least a portion of the defect occluder, and reversibly looped over an anchor element so as to permit reversible collapse the defect occluder for selective ingress and egress from a delivery catheter. The snare element is reversibly engageable with the anchor element so as to reversibly retain the at least one suture loop upon the anchor element, and thereby hold the defect occluder in a posture for reversible free-floating tethered deployment in a defect while being observable in a final position prior to release.

  • Patent number: 6659981
    Abstract: A delivery catheter for delivering an intra-bodily medical device to an internal bodily site. The delivery catheter includes an elongated shaft defining a proximal section and a distal section. A delivery lumen is formed by the shaft, extending from the proximal section and terminating at an opening formed proximal the distal section. Finally, a locator is formed by the distal section, and is configured to locate a target site. In one preferred embodiment, the locator is elongated, having a diameter less than that of a remainder of the shaft. In another preferred embodiment, the delivery catheter includes a steering device capable of effectuating a bend both proximal and distal the opening for steering the locator to a target site.
