A system and method for assisting a heart in pumping blood, wherein the heart has external force requirements that need to be externally applied to the heart using a cardiac assist device that is powered by a drive fluid. The cardiac assist device is powered by a drive fluid having a pressure/flow profile that is customized to the needs of the heart. The pressure/flow profile is generated by a displacement pump. If the pressure/flow profile requires pressures that cannot be made by the displacement pump, then the pressure/flow profile can be altered by venting pressure and/or adding pressurized fluid into the system. In this manner, a precise pressure/flow profile can be produced that meets the exact needs of a heart being acted upon by a cardiac assist device.
A system for assisting a heart in pumping blood, wherein the heart has external force requirements that need to be externally applied to the heart in order for the heart to pump more effectively, said system comprising:
A method for assisting a heart in pumping blood, wherein the heart has external force requirements that need to be externally applied to the heart in order for the heart to pump more effectively, said method comprising:
A pump system for producing an acting pressure/flow profile in a drive fluid required to drive a direct cardiac compression device, said system comprising:
