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.
Claims13
A system for the delivery of therapy to a patient's heart, comprising:
- a controller-transmitter, wherein the controller-transmitter is configured to transmit acoustic energy into the patient's body;
- and
- an acoustic receiver-stimulator having an electrode, wherein the acoustic receiver-stimulator is configured to receive at least a portion ofthe acoustic energy from the controller-transmitter, to convert the acoustic energy to electrical energy, and to deliver the electrical energy to the patient's heart via the electrode, and wherein the controller-transmitter is configured to transmit the acoustic energy into the patient's body to provide two or more of the following functions—
- (a) direct therapeutic ultrasound sonication of heart tissue to improve cardiac function or prevent deterioration of cardiac function,
- (b) leadless electrical pacing via the acoustic receiver-stimulator to improve cardiac function or prevent deterioration of cardiac function, and
- (c) leadless electrical cardiac contractility modulation via the acoustic receiver-stimulator to improve cardiac function or prevent deterioration of cardiac function.

A method for the delivery of therapy to a patient's heart, the method comprising:
- transmitting acoustic energy with an acoustic controller-transmitter into the patient's body and to an acoustic receiver-stimulator to provide two or more of the following functions—
- (a) direct therapeutic ultrasound sonication of heart tissue to improve cardiac function or prevent deterioration of cardiac function,
- (b) leadless electrical pacing via the acoustic recevier-stimulator to improve cardiac function or prevent deterioration of cardiac function, and
- (c) leadless electrical cardiac contractility modulation via the acoustic receiver-stimulator to improve cardiac function or prevent deterioration of cardiac function.
