1. A method of disposing an activation device on a carotid sinus of a patient, the carotid sinus having a circumference, the method comprising the steps of:
- providing an activation device having a base and a plurality of electrodes; and
positioning the device proximate the carotid sinus such that the base extends around at least a substantial portion of the circumference of the carotid sinus and the electrodes extend around the carotid sinus less than the base.

Abstract
Devices, systems and methods by which the blood pressure, nervous system activity, and neurohornonal activity may be selectively and controllably reduced by activating baroreceptors. A baroreceptor activation device is positioned near a baroreceptor, preferably in the carotid sinus. The baroreceptor activation device may utilize 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.
