Abstract
A system configured to be at least partially implanted along an aorta includes an inelastic, static member and a pinching member. The pinching member is configured to receive an activation signal at an activation rate and in response to the activation signal, repeatedly compress the aorta at the second location at the activation rate to pump fluid within the aorta in a desired pumping direction. The system is configured to selectively control wave reflections in order to achieve both improved wave dynamics to reduce cardiac load and increased (or at least non-diminished) blood flow to targeted organs within the cardiovascular system.
Claims21
A system configured to be at least partially implanted in mammal along an aorta, the system comprising:
- an inelastic member comprising a biocompatible material, the inelastic member configured to surround at least a portion of an outer surface of an aorta at a first location along the aorta;
- and
- a pinching member comprising a second biocompatible material, the pinching member configured to surround at least a second portion the outer surface of the aorta at a second location along the aorta,
- wherein the pinching member is further configured to receive an activation signal at an activation rate and in response to the activation signal, repeatedly compress the aorta at the second location at the activation rate to pump fluid within the aorta in a desired pumping direction.
