1. A system for the delivery of therapy to a heart of a patient, comprising:
a housing;
a sensor carried by the housing and configured to sense a physiologic parameter of the patient;
an acoustic transmitter carried by the housing and configured to transmit acoustic energy into a body of the patient; and
control circuitry carried by the housing and operably coupled to the sensor and the acoustic transmitter, wherein
the control circuitry is configured to control the acoustic transmitter, based at least in part on the physiologic parameter sensed via the sensor, to:
adjust a therapy for improving cardiac function and/or preventing deterioration of cardiac function of the heart of the patient,
selectively activate a remote receiver-stimulator implanted at the heart of the patient to deliver excitatory therapy,
selectively activate the remote receiver-stimulator to deliver non-excitatory therapy, and
selectively provide direct sonification of cardiac tissue of the heart of the patient.
