  • Helical tissue anchor device and delivery system
    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.
