1. An implantable cardiac therapy device having
a cardiac assist pump, which is configured to connect to a respective ventricle of a heart and a respective associated artery and when activated, is configured to pump blood from the respective ventricle into the respective associated artery and thus assist or relieve the respective ventricle; a defibrillation unit configured to deliver a defibrillation shock in response to a ventricular fibrillation; a control unit, which is connected to the cardiac assist pump and the defibrillation unit, wherein said control unit is configured to control the cardiac assist pump and the defibrillation unit and, in case of said ventricular fibrillation, to
activate the cardiac assist pump and the defibrillation unit in a coordinated manner such that
the cardiac assist pump first increases performance to initially provide a pressure relief of the respective ventricle, andthe defibrillation unit only subsequently delivers said defibrillation shock, when the pressure relief of the respective ventricle is provided; a pressure sensor which indicates a ventricular internal pressure and provides an output signal, wherein the control unit is connected to the pressure sensor, wherein the pressure sensor is located inside the cardiac assist pump, and wherein the pressure sensor is configured to detect a pressure in the respective ventricle and wherein the control unit is configured to control either the defibrillation unit or the cardiac assist pump or both, as a function of the output signal of the pressure sensor; and, a programmable timer, which is connected to the control unit or is a component thereof, wherein the control unit is configured to additionally control the delivery of the defibrillation shock through use of the programmable timer so that a defined runtime of the cardiac assist pump with increased performance is ensured before delivery of the defibrillation shock occurs. |
