Abstract
Methods for cardiac ventricular restoration include delivering an implantable expandable device into the ventricle via a catheter. The expandable device is anchored either to the wall of the left ventricle or to the inter-ventricular septum and then expanded. When expanded, the device assumes a size and shape which fills the lower portion of the ventricular cavity restoring the normal volume and ellipsoid shape of the remaining portion of the cavity and favorably altering myocardial oxygen demand and wall stress.
