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.
