Abstract: A device for treating heart failure in a patient. The device comprising a body, at least one passage through the body, at least one one way valve in the passage and a mounting means adapted for mounting the body in an opening provided in the patient's atrial septum. In use, the device is oriented such that, when the patient's left atrial pressure exceeds the patient's right atrial pressure by a predetermined amount, the one way valve(s) opens to allow blood flow through the passage(s) from the left atrium to the right atrium to thereby reduce the left atrial pressure.

Abstract: Devices, systems, and methods for reducing stress on a blood vessel are disclosed herein. For example, a method of treating effects of dementia comprises positioning a damping device along an artery that provides blood to a brain of a person so that an inner surface of the damping device contacts an outer surface of the artery. Wherein an inner diameter of the inner surface changes in response to a wavefront of blood passing through the artery and thereby attenuates energy of the wavefront.
