Claim 0:
1. A catheter pump, comprising:
a catheter body having at least one lumen therethrough, and comprising a distal end and a proximal end;
an expandable impeller assembly, the expandable impeller assembly including an expandable impeller and an expandable cannula coupled to the distal end of the catheter body and housing the expandable impeller, the expandable cannula comprising a substantially straight segment having a distal inlet and a proximal outlet;
wherein the catheter body comprises a proximal vessel contact zone and a distal vessel contact zone that are each proximal to the substantially straight segment, the proximal vessel contact zone and distal vessel contact zone having a stiffness configured to, when formed in a curved shape deployed around an outer radius of the aortic arch, bear against the outer radius of the aortic arch with a restoring force in order to retain the catheter body in place around the outer radius of the aortic arch, thereby stabilizing the substantially straight segment when straddled across an aortic valve.
