Claim 9:
10. An apparatus comprising:
an aortic pressure-loss-reduction device configured to be implanted in an ascending aorta of a subject, the aortic pressure-loss-reduction device comprising a frame, and a material that is configured to impede blood flow therethrough coupled to at least a portion of the frame, the aortic pressure-loss-reduction device being configured such that in a non-radially-constrained configuration of the device, the device defines:
an upstream anchor,
a downstream anchor, at least a portion of the downstream anchor being defined by the frame and not including any material coupled to the frame, and
an intermediate portion of the device that defines a conduit through the aortic pressure-loss-reduction device; and

a catheter configured to be inserted into the subject's ascending aorta, while housing the aortic pressure-loss-reduction device inside the catheter in a radially constrained configuration, with the upstream anchor disposed within the catheter distally with respect to the downstream anchor, the catheter comprising:
a proximal covering sheath configured to be retracted such as to sequentially:
uncover the intermediate portion of the aortic pressure-loss-reduction device to allow the intermediate portion to at least partially assume its non-constrained configuration, and
uncover a portion of the downstream anchor, such that the uncovered portion of the downstream anchor includes the portion of the frame that does not have the material coupled thereto, while maintaining the downstream anchor in an at least partially-radially-constrained state;

a distal covering sheath of the catheter configured, subsequent to the proximal covering sheath being retracted such as to uncover at least the portion of the downstream anchor, to be advanced distally as to cause the upstream anchor to anchor an upstream end of the aortic pressure-loss-reduction device to the subject's ascending aorta, by the upstream anchor radially expanding against an inner wall of the ascending aorta, the upstream anchor having material covered thereto, such that blood flows from the aortic valve into an upstream end of the device and out of the uncovered portion of the downstream anchor;
the proximal covering sheath being further configured, subsequent to the distal covering sheath being advanced distally, to be further retracted, such as to cause the downstream anchor to anchor a downstream end of the aortic pressure-loss-reduction device to the subject's ascending aorta, by the downstream anchor radially expanding against the inner wall of the ascending aorta.
