A direct cardiac compression device includes a flexible outer layer configured to fit about at least a portion of a living heart and contains at least a first pericardial electrode facing outward therefrom. The pericardial electrode is configured to detect an electrocardiogram of the living heart. The device further includes at least one inflatable active chamber inside the flexible outer layer facing the living heart, and a port operably connected with the at least one inflatable active chamber and configured to facilitate inflation and deflation of the at least one active chamber by an actuator to cause periodic direct compression of the living heart. The actuator may be controlled to inflate and deflate the at least one active chamber using the electrocardiogram signal collected from the first pericardial electrode.

A fluid controlled system for a cardiac assist device and its method of operation. The cardiac assist device has a cup assembly with a receptacle area. The cup assembly has at least one inflatable membrane that expands into the receptacle area. A single pressure tube connects the cup assembly to a fluid pump. A valve assembly is incorporated into the cardiac assist device. The valve assembly includes at least one valve that controls fluid flow between the inflatable membranes and the pressure tube and/or fluid flow between the receptacle area and the pressure tube. The valve assembly controls fluid flow to advance the cup assembly onto the heart, to maintain the cup assembly in an operable position, to operate the cup assembly, and to remove the cup assembly.

A system and method of increasing the pumping efficiency of an individual's heart, wherein an actual pumping efficiency is compared to an optimal pumping efficiency to determine a force assist profile. A cardiac assist device is created that will apply the force assist profile to the heart. The cardiac assist device is surgically inserted in vivo to physically affect the heart. The cardiac assist device has an outer shell and at least one inflatable membrane that passes over the ventricles of the heart, wherein the inflatable membrane is inflated and deflated in accordance with a pressure profile provided by a pneumatic pump. The outer shell embodies outer shell strain characteristics. Each inflatable membrane embodies membrane strain characteristics. The force assist profile is a function of the outer shell strain characteristics, the membrane strain characteristics, and the pressure profile.
