Percutaneous cardiac ventricular geometry restoration device and treatment for heart failure
First Claim
1. An apparatus for percutaneous cardiac ventricular restoration, comprising:
- an expandable device constructed in a size and shape which permit it to be delivered to an interior of the ventricle in an unexpanded state via a blood vessel and being constructed to permit it to be expanded once it has been delivered to the interior of the ventricle; and
an anchoring device coupled to the expandable device and having structure which permits it to anchor the expandable device to the ventricular wall or the ventricular septum.

Abstract
Methods for percutaneous 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. Catheters used in heart pacer electrode implantation are adaptable for use with the implantable expandable device of the invention.
