1. A system for treating a native heart valve, the system including a delivery configuration and a deployed configuration, the system comprising:
a flexible canopy;
an elongated tether configured to be placed under tension in situ, the elongated tether including an elastic portion and an inelastic portion coupled to the elastic portion, wherein the elastic portion is at least as long as the inelastic portion with a ratio of the elastic portion to the inelastic portion being between 50/50 and 70/30 and a proximal end of the elongated tether is attached to a distal end of the flexible canopy; and
a distal anchor configured to be embedded into tissue of a ventricle, wherein a distal end of the elongated tether is coupled to the distal anchor,
wherein when the system is in the deployed configuration, a proximal end of the flexible canopy is anchored to an annulus of the heart valve and the distal end of the elongated tether is anchored to tissue of a ventricle via the distal anchor such that the elongated tether is placed under tension.
