Abstract:
Devices, systems, and methods for reducing stress on a blood vessel are disclosed herein. A damping device (100) configured in accordance with embodiments of the present technology can include an anchoring member (104) coupled to a flexible, compliant damping member (102) including a generally tubular sidewall having an outer surface (115), an inner surface (113) defining a lumen configured to direct blood flow, a first end portion (106) and a second end portion (108), and a damping region (120) between the first and second end portions (106, 108). The inner and outer surfaces (113, 115) of the damping member (102) can be spaced apart by a distance that is greater at the damping region (120) than at either of the first or second end portions (106, 108). When blood flows through the damping member (102) during systole, the damping member (102) 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 (100).
