Publication number: 20070185542Abstract: Devices, systems and methods are described 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 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.Type: ApplicationFiled: December 28, 2006Publication date: August 9, 2007Applicant: CVRx, Inc.Inventors: Stephen Bolea, Robert Kieval, Bruce Persson, David Serdar, Peter Keith, Eric Irwin, Martin Rossing
