Claim 19:
20. A method comprising:
placing an aortic pressure-loss-reduction device inside an ascending aorta of a subject, the aortic pressure-loss-reduction device including a frame and a material layer coupled to an inside of at least a portion of the frame, the material being configured to impede blood flow therethrough; and
deploying the aortic pressure-loss-reduction device inside the ascending aorta, such that the frame of the aortic pressure-loss-reduction device defines:
an upstream anchor portion that radially expands against an inner wall of a subject's ascending aorta, such as to anchor an upstream end of the aortic pressure-loss-reduction device to the subject's ascending aorta,
an intermediate portion that defines a conduit therethrough, such that blood flows through the device via the conduit, at least a portion of the conduit diverging, such that a downstream end of the diverging portion has a greater cross-sectional area than an upstream end of the diverging portion,
a downstream anchor portion that radially expands against an inner wall of a subject's ascending aorta, such as to anchor a downstream end of the aortic pressure-loss-reduction device to the subject's ascending aorta,
a first set of sinusoidal struts disposed between a downstream end of the upstream anchor and an upstream end of the intermediate portion, the sinusoidal struts forming a folded portion between the downstream end of the upstream anchor and the upstream end of the intermediate portion, and
an upstream end of the intermediate portion being reinforced with respect to at least a central portion of the intermediate portion, such that in response to a diameter of the upstream anchor changing by an absolute amount, an absolute change in a diameter of the upstream end of the intermediate portion is less than the absolute amount by which the diameter of the upstream anchor changes.
