<p>Artificial stimulation apparatus comprising a controller 8 comprising a receiver for receiving signal data, a processor 22 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 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 6 to the receiver of the controller; and at least one stimulation stent (10, 12, 14, 16, 18) for location in at least one vein of the subject distal of the sensing stent comprising a receiver for receiving signal data 20 from the transmitter of the controller and an electrode assembly for providing a stimulating electrical signal to the heart of the subject in response to the data received. A stent assembly for providing stimulation to heart tissue at a target site comprises a stent body of a size to be implanted and retained in the position proximal to the target site; and an electrode assembly arranged to extend longitudinally from the stent body within the target blood vessel in a distal direction from the proximal position to the target site to be stimulated.</p> |
