Abstract

A system delivers stimulation to volume receptors in the cardiovascular system to induce diuresis in a patient suffering volume overload. The system senses a volume signal indicative of a level of fluid retention in the patient's body and controls the delivery of the stimulation using the volume signal. In various embodiments, the stimulation includes one or more of electrical stimulation, which delivers electrical pulses to the volume receptors, and mechanical stimulation, which physically stretches the volume receptors.

Description

[0001] priority claim [0002] Priority is claimed to US Patent Application Serial No. 11 / 748,171, filed May 14, 2007, which is hereby incorporated by reference. technical field [0003] This document relates generally to medical devices and in particular to implantable systems for regulating blood volume by stimulating volume receptors. Background technique [0004] The heart is the center of the human circulatory system. It includes an electro-mechanical system that performs two main pumping functions. The left side of the heart, including the left atrium and left ventricle, draws oxygenated blood from the lungs and pumps it to the various organs of the body, giving these organs the oxygen they need to metabolize. This pumped blood flow is called cardiac output. The right side of the heart, including the right atrium and right ventricle, draws deoxygenated blood from the organ and pumps it to the lungs, where the blood is oxygenated. The pumping function is accomplishe...
