Abstract
A method for reducing regurgitation in a mitral valve using a blood flow controlling apparatus. The blood flow controlling apparatus comprises an anchoring means, preferably arranged to anchor the apparatus to a wall of the left ventricle. The blood flow controlling apparatus further comprises a valve means configured to expand in a direction transverse to blood flow. The valve means is preferably positioned within a native mitral valve and expands for making contact with the mitral valve leaflets during ventricular systole, thereby preventing blood from regurgitating back through the mitral valve into the left atrium. When blood flows from the left atrium to the left ventricle during ventricular diastole, the valve means collapses for allowing blood to pass freely through the mitral valve.
