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.

Independent Claims | See all claims (24)

  1. 1. An apparatus for cardiac ventricular restoration of a heart having a ventricular wall and a ventricular septum, comprising: an asymmetrical balloon constructed in a size and shape which permit the balloon to be delivered to an interior of the ventricle in an unexpanded state and being constructed to permit the balloon to be expanded once the balloon has been delivered to the interior of the ventricle; said balloon having a centrally located stem with at least one inflation port, said stem including a coupling device having structure which permits the stem to couple to an inflation tube and a valve which automatically closes when the inflation tube is uncoupled from the coupling device; and an anchoring device coupled to the balloon and having structure which permits the balloon to anchor the balloon to the ventricular wall or the ventricular septum.
  2. 17. An apparatus for cardiac ventricular restoration of a heart having a ventricular wall and a ventricular septum, comprising: an asymmetrical balloon constructed in a size and shape which permit the balloon to be delivered to an interior of the ventricle in an unexpanded state and being constructed to permit the balloon to be expanded once the balloon has been delivered to the interior of the ventricle, said balloon includes a perforate outer surface and inner and outer chambers, said outer surface in communication with said outer chamber; and an anchoring device coupled to the balloon and having structure which permits the balloon to anchor the balloon to the ventricular wall or the ventricular septum, wherein when fluid is injected into and removed from said inner chamber said volume of said balloon is modified, and when suction is applied to said outer chamber negative pressure is applied at said perforate outer surface.
  3. 18. An apparatus for cardiac ventricular restoration of a heart having a ventricular wall and a ventricular septum, comprising: a balloon constructed in a size and shape which permit the balloon to be delivered to an interior of the ventricle in an unexpanded state and being constructed to permit the balloon to be expanded once the balloon has been delivered to the interior of the ventricle; a basket located relative to the balloon to expand the balloon to an expanded state after the balloon is in the interior of the ventricle; and an anchoring device coupled to the balloon and having structure which permits the balloon to anchor the balloon to the ventricular wall or the ventricular septum, wherein said balloon is absent of fluid when in an expanded state.
  4. 22. An apparatus for cardiac ventricular restoration of a heart having a ventricular wall and a ventricular septum, comprising: an asymmetrical balloon constructed in a size and shape which permit the balloon to be delivered percutaneously to an interior of the ventricle in an unexpanded state and being constructed to permit the balloon to be expanded once the balloon has been delivered to the interior of the ventricle; and an anchoring device coupled to the balloon and having structure which permits the balloon to anchor the balloon to the ventricular wall or the ventricular septum a delivery device having structure which permits the delivery device to deliver the balloon in the unexpanded state through a blood vessel to the interior of the ventricle; and an expandable basket to expand the balloon after the balloon is in the interior of the ventricle.
