A system for artificial stimulation of the heart of a subject, the system comprising a controller assembly comprising a receiver for receiving signal data, a processor for processing received signal data, and a transmitter for transmitting signal data; a sensing stent for location in the proximal coronary sinus of the subject, the sensing stent comprising a sensing electrode assembly for sensing atrial and/or ventricular signals from the heart of the subject and a transmitting assembly for transmitting signal data to the receiver of the controller assembly; a stimulation stent for location in a vein of the subject distal of the sensing stent, the stimulation stent comprising a receiver for receiving signal data from the transmitter of the controller assembly and an electrode assembly for providing a stimulating electrical signal to the heart of the subject in response to the data received; and a defibrillator assembly for providing stimulation to the heart sufficient to defibrillate the heart in response to a signal received from the controller assembly. A method for providing pacing and defibrillation stimulation to the heart is also provided. A novel stent assembly having combined sensing and defibrillating functions is also disclosed. |
