A method of reducing regurgitation between native leaflets of an atrioventricular heart valve includes advancing a delivery catheter through a sheath, wherein the delivery catheter has a valve leaflet coaptation element mounted over a distal end portion. The coaptation element is positioned within the heart valve and is permitted to radially expand from a compressed configuration to an enlarged configuration for filling a gap between the native leaflets of the heart valve. After deployment, the position of the coaptation element is fixed relative to the heart valve, thereby reducing regurgitation between the native leaflets of the heart valve and improving heart function.

Methods for reducing cardiac valve regurgitation

The present invention relates to devices and methods for improving the function of a defective heart valve, and particularly for reducing regurgitation through an atrioventricular heart valve&#x2014;i.e., the mitral valve or tricuspid valve. For a tricuspid repair, the device includes an anchor deployed in the tissue of the right ventricle, in an orifice opening to the right atrium, or anchored to the tricuspid valve. A flexible anchor rail connects to the anchor and a coaptation element on a catheter rides over the anchor rail. The catheter attaches to the proximal end of the coaptation element, and a locking mechanism fixes the position of the coaptation element relative to the anchor rail. A proximal anchoring feature fixes the proximal end of the coaptation catheter subcutaneously adjacent the subclavian vein. The coaptation element includes an inert covering and helps reduce regurgitation through contact with the valve leaflets.
