Abstract:
1. A cardiac pacing system comprising: at least one leadless cardiac pacemaker configured for implantation in electrical contact with a cardiac chamber and configured to perform cardiac pacing functions in combination with a co-implanted implantable cardioverter-defibrillator (ICD), the at least one leadless cardiac pacemaker comprising a pulse generator comprising a capacitor, the pulse generator configured to generate pulses adapted to perform cardiac pacing and to generate pulses encoding information for transmission as communication signals by dividing an output waveform from the capacitor into a plurality of separate pulses, and at least two electrodes configured to deliver generated pulses, sense evoked and/or natural cardiac electrical signals, and bidirectionally communicate with a non-implanted programmer by operation of the pulse generator to transmit generated pulses operative as communication signals.
