Abstract
Inflatable heart valve implants and methods utilizing those valves designed to reduce or eliminate the regurgitant jet associated with an incompetent atrioventricular valve. The heart valve implants, which are deployed via a transcatheter venous approach, comprise an inflatable balloon portion movably connected to an anchored guide shaft and movable from a distal position in the ventricle to a more proximal position between leaflets of a native atrioventricular valve. The range of movement of the inflatable valve body can be adjusted in situ after or before the guide shaft has been anchored to native heart tissue during surgery.
