Publication number: 20190307459Abstract: 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.Type: ApplicationFiled: May 24, 2019Publication date: October 10, 2019Inventors: David Stephen Celermajer, Anthony Ujhazy, Mike Wallace, Zoran Milijasevic, Johnathon Choi
