Abstract
The present invention relies on a controller-transmitter device to deliver ultrasound energy into cardiac tissue in order to directly improve cardiac function and/or to energize one or more implanted receiver-stimulator devices that transduce the ultrasound energy to electrical energy to perform excitatory and/or non-excitatory treatments for heart failure. The acoustic energy can be applied as a single burst or as multiple bursts.
Claims5
A system for heart failure therapy comprising:
- one or more acoustic receiver-stimulators having an electrode assembly adapted to be implanted in direct contact with cardiac tissue at one or more heart locations selected to provide a preferred pattern of activation and/or mechanical contraction;
- and
- an acoustic controller-transmitter, wherein the controller-transmitter and receiver-stimulator are adapted to transmit and receive acoustic energy which provides both energy and signal information to the receiver-stimulator sufficient to stimulate the heart, wherein the receiver-stimulator comprises an acoustic receiver which receives acoustic energy and generates alternating current, converter circuitry which produces a direct current or waveform from the alternating current to stimulate the cardiac tissue, and electrodes adapted to deliver the direct current or waveform to myocardial tissue.
A system for the delivery of therapy to a patient's heart, comprising:
- an acoustic controller-transmitter, wherein the controller-transmitter is adapted to transmit acoustic energy to provide two or more of the following functions:
- (a) ultrasound sonication of heart tissue to improve cardiac function, (b) ultrasound sonication of heart tissue to prevent deterioration of cardiac function, (c) leadless pacing to improve cardiac function, (d) leadless pacing to prevent deterioration of cardiac function, (e) leadless cardiac contractility modulation to improve cardiac function, and (f) leadless cardiac contractility modulation to prevent deterioration of cardiac function;
- wherein cardiac function is one or more of contractility, vasodilation, tissue perfusion, or aortic pressure.
