Abstract
A system for treating valvular regurgitation in a heart valve includes a flexible canopy and an elongated tether including an elastic portion and an inelastic portion. When the system is in a deployed configuration, a proximal end of the flexible canopy is coupled to an annulus of the heart valve and a distal end of the elongated tether is coupled to a ventricle. The flexible canopy is configured to overlay a first native leaflet of the heart valve, and tension on the elongated tether is applied and/or adjusted to prevent the first leaflet from prolapsing, to maximize coaptation of the flexible canopy with a second native leaflet of the heart valve, and to minimize regurgitation of the heart valve.
