摘要： A TET system is operable to vary an amount of power transmitted from an external power supply to an implantable power unit in accordance with a monitored condition of the implantable power unit. The amount of power supplied to the implantable power unit for operating a pump, for example, can be varied in accordance with a cardiac cycle, so as to maintain the monitored condition in the power circuit within a desired range throughout the cardiac cycle.

摘要： A ventricular assist device incorporating a rotary pump, such as a rotary impeller pump is implantable in fluid communication with a ventricle and an artery to assist blood flow from the ventricle to the artery. The device includes a pump drive circuit supplying power to the pump, one or more sensors for sensing one or more electrophysiological signals such as electrogram signals in and a signal processing circuit connected to the sensors and the pump drive circuit. The signal processing circuit is operative to detect the sensor signals and control power supplied to the pump from the pump drive circuit so that the pump runs in a pulsatile mode, with a varying speed synchronized with the cardiac cycle so that it operates in copulsation or counterpulsation with the cycle. The cardiac cycle for purposes of synchronization can also be based on an average of two or more cardiac cycles.

摘要： A ventricular assist system including an implantable rotary pump, a pump drive circuit for supplying power to the pump, and a signal processing circuit receiving one or more electrophysiological signals and one or more physiological signals of the subject. The signal processing circuit is operable to receive inputs from the one or more electrophysiological sensors and the physiological sensor, and determine the presence or absence of a non-normal sinus cardiac rhythm condition based on the input from the electrophysiological sensors. In the presence of a non-normal sinus rhythm, the circuit operates the pump in a modified mode of operation. In the absence of a non-normal sinus rhythm, the circuit operates the pump in a normal mode of operation. In either case, the circuit controls the power to the pump and/or speed of the pump based on the input from the physiological sensor and the mode of operation.

摘要： A blood pump incorporating a rotary pump such as a rotary impeller pump implantable in fluid communication with a ventricle and an artery to assist blood flow from the ventricle to the artery. The device may include a pump drive circuit supplying power to the pump, one or more sensors for sensing one or more electrophysiological signals such as subcutaneous, pre-cordial ECG signals and a signal processing circuit connected to the sensors and to the pump drive circuit. The signal processing circuit is operative to detect the sensor signals and control power supplied to the pump from the pump drive circuit so that the pump may run in a normal sinus rhythm mode, with a varying speed synchronized with the cardiac cycle. When an ischemic or myocardial infarction condition is detected, the pump drive circuit may also run the pump in an ischemia or myocardial infarction mode different from the normal sinus rhythm mode.
