  • Patent number: 11446023
    Abstract: A delivery system for delivering a plurality of helical tissue anchors to repair a wall defect. Coaxially contained within the outer sheath are inner tubular members. The first inner tubular member designed to deploy a first helical tissue anchor, a second inner tubular member designed to deploy a second helical tissue anchor, and a centered inner tubular member contains a cinching mechanism. The two helical tissue anchors are connected to a suture or strap that pull the two helical tissue anchors together to close a tissue defect. A cinching mechanism holds the anchors and tissue defect together and cut the suture or strap.

  • Publication number: 20210361280
    Abstract: Disclosed herein are methods and devices for securing soft tissue to a rigid material such as bone. A bone anchor is described that comprises an anchor body with expandable tines and a spreader that expands the tines into bone. Also disclosed is a bone anchor that comprises a base and a top such that suture material may be attached to apertures in the anchor top or else compressed between surfaces on the base and top to secure the suture to the anchor. Also described is an inserter that can be used to insert the bone anchor into bone and move the spreader relative to the anchor body attach suture material. Also described is an inserter that can be used to insert the bone anchor into bone and move the anchor top relative to the anchor body or anchor base to attach to or clamp suture material there between.

  • Publication number: 20070142835
    Abstract: A bone anchor is described having pre-attached suture material. After insertion, lateral wings can be deployed on the bone anchor to prevent anchor pull-out. The suture may be attached at the tip of the anchor by tying it to a wire hook secured in a cavity in the anchor tip. The anchor may be inserted and deployed using an anchor inserter that is configured to apply an axial force to the anchor, thereby deforming the anchor to form the lateral wings.
