Devices and methods for cardiovascular reflex control via coupled electrodes
First Claim
1. A method for activating a baroreflex, said method comprising:
- transmitting a control signal from a transmitting coil implanted in a vein proximate the baroreceptor;
wherein the control signal is wirelessly received by an activation device comprising both (a) an electrode structure and (b) a receiving coil, separately formed from the electrode structure wherein the activation device is implanted in or on a blood vessel proximate to the baroreceptor, whereby the control signal induces electrical current in the receiving coil, which current flows to the electrode structure which activates the baroreceptor to produce a baroreflex.

Abstract
Devices, systems and methods are disclosed by which the blood pressure, nervous system activity, and neurohormonal activity may be selectively and controllably reduced by activating baroreceptors. A baroreceptor activation device is positioned near a baroreceptor, preferably a baroreceptor located in the carotid sinus. A control system may be used to modulate the baroreceptor activation device. The control system may utilize an algorithm defining a stimulus regimen which promotes long term efficacy and reduces power requirements/consumption. The baroreceptor activation device may utilize RF-coupled or other electrodes to activate the baroreceptors. The electrodes may be adapted for connection to the carotid arteries at or near the carotid sinus, and may be designed to minimize extraneous tissue stimulation.
