Claim 0:
1. A method comprising:
implanting an aortic pressure-loss-reduction device in an ascending aorta of a subject, the aortic pressure-loss-reduction device including a frame and a material that is configured to impede blood flow therethrough coupled to at least a portion of the frame, by, sequentially:
while the aortic pressure-loss-reduction device is inside a catheter, placing a distal end of the catheter within the subject's ascending aorta, the aortic pressure-loss-reduction device being disposed within the catheter such the device is maintained in a radially-constrained configuration and such that an upstream anchor of the device is disposed distally within the catheter with respect to a downstream anchor of the device;
retracting a proximal covering sheath of the catheter, such as to:
uncover an intermediate portion of the aortic pressure-loss-reduction device to allow the intermediate portion to at least partially assume its non-constrained configuration, the intermediate portion of the device being configured to define a conduit through the device; and
uncover a portion of the downstream anchor, such that the uncovered portion of the downstream anchor includes a 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;

advancing a distal covering sheath of the catheter, such 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 being having material coupled 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; and
further retracting the proximal covering sheath of the catheter, 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 an inner wall of the ascending aorta.
