Abstract:
Methods and devices for repairing a cardiac valve. A minimally invasive procedure includes creating an access in the apex region of the heart through which one or more instruments may be inserted. The device can implant artificial heart valve chordae tendineae into cardiac valve leaflet tissues to restore proper leaflet function and prevent reperfusion. The device punctures the apex of the heart and travels through the ventricle. The tip of the device rests on the defective valve and punctures the valve leaflet. A suture or a suture/guide wire combination is inserted, securing the top of the leaflet to the apex of the heart. A resilient element or shock absorber mechanism adjacent to the outside of the apex of the heart minimizes the linear travel of the device in response to the beating of the heart or opening/closing of the valve.
