  • Publication number: 20080215111
    Abstract: Devices, systems and methods are described which control blood pressure, nervous system activity, and neurohormonal activity by activating baroreceptors. By selectively and controllably activating baroreceptors, the present invention reduces excessive blood pressure, sympathetic nervous system activity and neurohormonal activity, thereby minimizing their deleterious effects on the heart, vasculature and other organs and tissues. A baroreceptor activation device is positioned near a low-pressure baroreceptor, preferably in the venous system, heart, or pulmonary vasculature.
