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.

-25. (canceled)
An apparatus for cardiac ventricular restoration of a heart having a ventricular wall and a ventricular septum, comprising:
- a basket constructed in a size and shape which permit the basket to be delivered percutaneously in an unexpanded state to an interior of the ventricle and being constructed to permit the basket to be expanded into an expanded state once the basket has been delivered to the interior of the ventricle;
- a fluid impermeable membrane coupled to the basket to conform in size and shape to the basket when the basket is in the expanded state;
- an anchoring device coupled to a distal end of the apparatus and having structure which permits the basket to be anchored to the ventricular septum;
- and
- a delivery device having structure which permits the delivery device to deliver the basket and membrane balloon in the unexpanded state through a blood vessel to the interior of the ventricle.
An apparatus for percutaneous cardiac ventricular restoration, comprising:
- a balloon constructed in size and shape which permit said balloon to be delivered to an interior of a ventricle in an unexpanded state via a blood vessel and being constructed to permit said balloon to be expanded into an expanded state once said balloon has been delivered to the interior of the ventricle;
- and
- an anchoring device coupled to the balloon and having structure which permits said balloon to anchor the balloon to a ventricular apex without coupling the balloon to a ventricular septum or a ventricular wall.
A method for ventricular restoration of the heart, comprising:
- permanently implanting a volume-changing device at an apex of a ventricle of the heart;
- and
- expanding the volume-changing device so as to reduce the available blood volume of the ventricle.
