  • Helical cardiac anchors for minimally invasive heart valve repair
    Patent number: 12208007
    Abstract: An anchor assembly is configured to implant a cardiac anchor into a heart wall of a patient to anchor a suture configured to extend from a valve leaflet of the heart as an artificial chordae. The anchor assembly can include an anchor hub defining an open interior and a helical coil extending distally from the anchor hub and having a sharpened tip configured to embed the helical coil into the heart wall upon rotation of the helical coil. A spring can be disposed within the open interior of the anchor hub. Compressing the spring distally can create an open space within the open interior of the anchor hub for a suture extending through the anchor hub to slide freely and releasing compression on the spring can cause the spring to expand in a proximal direction to clamp the suture within the open interior of the anchor hub.
