Apparatus for artificial cardiac stimulation and method of using same
First Claim
1. A method for providing stimulation to a heart of a subject, the heart comprising a coronary sinus having a proximal region with an ostium, a left atrium, a left ventricle, an oblique vein and a middle cardiac vein, the method comprising:
- sensing electrical activity of the heart at the ostium of the proximal region of the coronary sinus using a single sensing stent, the single sensing stent implanted in the coronary sinus, the sensing stent operable for sensing purposes only;
transmitting first signal data from the ostium of the coronary sinus to a controller;
generating second signal data for providing electrical stimulation to target tissue of the heart in response to the signal data received from the ostium of the coronary sinus transmitting the second signal data to a stimulation stent for stimulation of the target tissue, wherein the stimulation stent is located in a vein of the heart distal of the ostium of the coronary sinus; and
providing electrical stimulation to the target tissue of the heart in response to the second signal data, wherein the electrical stimulation is provided to the tissue of the heart distal of the ostium of the coronary;
wherein signal data are transmitted from the sensing stent to the controller and from the controller to the stimulation stent remotely without using leads.
