  • Publication number: 20190307459
    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.

  • Patent number: 10064626
    Abstract: Devices, systems, and methods for reducing stress on a blood vessel are disclosed herein. A damping device configured in accordance with embodiments of the present technology can include an anchoring member coupled to a flexible, compliant damping member including a generally tubular sidewall having an outer surface, an inner surface defining a lumen configured to direct blood flow, a first end portion and a second end portion, and a damping region between the first and second end portions. The inner and outer surfaces of the damping member can be spaced apart by a distance greater at the damping region than at the first or second end portions. When blood flows through the damping member during systole, the damping member absorbs a portion of the pulsatile energy of the blood, thereby reducing a magnitude of the pulse pressure transmitted to a portion of the blood vessel distal to the damping device.
