Abstract:
1. A method for stimulating cardiac muscle, said method comprising: implanting a receiver-stimulator at a cardiac stimulation site, wherein the receiver-stimulator is present in a sealed case; and subcutaneously implanting a controller-transmitter at a location remote from the cardiac stimulation site, wherein the controller-transmitter is present in a sealed case separate from that of the receiver-stimulator and is configured to detect a pacing signal of a separate cardiac pacemaker having leads implanted in a right ventricle or right atrium; wherein the controller-transmitter detects the pacing signal of the cardiac pacemaker; and upon detecting the pacing signal, generates acoustic energy which is received by the receiver-stimulator and converted by the receiver-stimulator into cardiac stimulation energy based on both energy and signal information included in the acoustic energy.
