Apparatus for artificial cardiac simulation and method of using the same
First Claim
1. A method for providing stimulation to a heart of a subject, the heart comprising a left atrium, a left ventricle, a right ventricle and a coronary sinus having an ostium, the method comprising:
- sensing electrical activity of the heart at the ostium of the coronary sinus using a sensing stent implanted at the ostium of the coronary sinus, the sensing stent not being operable to provide pacing stimulation to the heart;
transmitting first signal data from a proximal region of the coronary sinus to a controller assembly;
generating second signal data for providing electrical stimulation to target tissue of the heart in response to the signal data received from the proximal region of the coronary sinus;
transmitting the second signal data to a stimulation stent for stimulation of target tissue;
providing electrical stimulation to the target tissue of the heart from the stimulation stent in response to the second signal data; and
in the case of a detected fibrillation of the heart, generating third signal data for providing electrical stimulation to the heart sufficient for defibrillation, transmitting the third signal data to a defibrillator assembly; and
providing electrical stimulation to the heart from the defibrillator assembly.

Abstract
A system for artificial stimulation of the heart of a subject comprises a controller 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 and comprising a sensing electrode assembly for sensing atrial and/or ventricular signals from the heart of the subject and a transmitter for transmitting signal data to the receiver; a stimulation stent for location in a vein of the subject distal of the sensing stent and comprising a receiver for receiving signal data from the transmitter and an electrode assembly for providing a stimulating electrical signal to the heart 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.
