1. A device for placing in a cardiac valve to assist operation of natural cardiac valve leaflets, the device comprising:

  • a frame for anchoring the device, comprising a first portion configured to be placed upstream of the cardiac annulus and a second portion configured to be placed downstream of the cardiac annulus, and shaped to prevent the entire frame from shifting downstream of the cardiac valve annulus; and

    at least one anchor extension attached to the frame, the anchor extension configured and circumferentially arranged to extend downstream between the leaflets of the cardiac valve at commissures of the cardiac valve, long enough to extend below an edge of cardiac leaflets, away from a center axis of the frame and back upstream behind the natural leaflets, between the natural leaflet and a ventricle side wall, allowing movement of a natural cardiac leaflet, preventing the anchor extensions from shifting back from the downstream side of the annulus to the upstream side of the annulus.
