Apparatus and method for improving ventricular function
First Claim
1. An implantable apparatus, comprising:
- an inflow conduit having first and second ends spaced apart from each other by a sidewall portion;
an inflow valve operatively associated with the inflow conduit to provide for substantially unidirectional flow of blood through the inflow conduit from the first end to the second end of the inflow conduit;
a pouch having an interior chamber that defines a volume, the inflow conduit being in fluid communication with the interior chamber of the pouch; and
an outflow conduit in fluid communication with the interior chamber of the pouch to permit substantially free flow of fluid from the interior chamber of the pouch and into the outflow conduit, which terminates in an outflow annulus spaced from the pouch.

Abstract
An approach is disclosed for improving ventricular function of a patient'"'"'s heart. In one example, an implantable apparatus includes an inflow conduit having first and second ends spaced apart from each other by a sidewall portion. An inflow valve is operatively associated with the inflow conduit to provide for substantially unidirectional flow of blood through the inflow conduit from the first end to the second end of the inflow conduit. A pouch has an interior chamber that defines a volume. The inflow conduit is in fluid communication with the interior chamber of the pouch. An outflow conduit is in fluid communication with the interior chamber of the pouch to permit substantially free flow of fluid from the interior chamber of the pouch and into the outflow conduit, which terminates in an outflow annulus spaced from the pouch.

14. An implantable apparatus for improving ventricular function, comprising:
-
means for limiting a volume of blood received within an enlarged ventricle of the patient'"'"'s heart;
means for providing for substantially unidirectional flow of blood into the means for limiting;
means for providing a path for flow of blood from within the means for limiting and into an aorta of the patient'"'"'s heart; and
means, located within the means for providing a path, for providing for substantially unidirectional flow of blood out of the means for limiting and into the aorta. - View Dependent Claims (15, 16)

17. A method for improving ventricular function of a heart, comprising:
-
implanting a pouch in a ventricle of the heart, the pouch including an interior chamber that defines a volume;
mounting an inflow valve at a mitral position of the heart, the inflow valve being in fluid communication with the interior chamber of the pouch to provide for substantially unidirectional flow of blood from an atrium of the heart through the inflow valve and into the interior chamber of the implanted pouch; and
attaching an outflow conduit, which is in fluid communications with the interior chamber of the implanted pouch, near an aortic annulus to provide for substantially unidirectional flow of blood from the interior chamber of the pouch and into the aorta of the heart. - View Dependent Claims (18, 19, 20, 21)
