A buoy system for treating cardiac valve regurgitation comprising a movable plug having atrial and ventricular ends, wherein a through-hole passes from the atrial to the ventricular end, wherein during systole, the plug travels toward a cardiac atrium, wherein during diastole, the plug travels into a cardiac ventricle; a tether having atrial and ventricular ends, wherein the tether passes through the through-hole of the moving plug, wherein the atrial end of the tether projects into an atrium, wherein the atrial end of the tether includes a cap to engage a delivery tool; at least one distal anchor located in the ventricle, wherein the distal anchor is coupled to the ventricular end of the tether, and wherein the system is percutaneously delivered and optionally recaptured via catheter and recapture tool at the cap of the tether, respectively.
