Abstract: A catheter pump includes a catheter body having at least one lumen therethrough, and comprising a distal end and a proximal end. An expandable impeller assembly includes 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, the substantially straight segment configured to straddle an aortic valve. 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 configured to provide a force against an aortic arch to stabilize the expandable impeller assembly across the aortic valve.

Abstract: In one embodiment, a catheter pump assembly is disclosed. The catheter pump assembly can include an impeller assembly. A catheter body can be coupled with the proximal end of the impeller assembly, the catheter body having a reduced stiffness section disposed proximally of the impeller assembly. A sheath assembly can be configured to be translate over the catheter body relative to the impeller assembly from an impeller assembly delivery position to an impeller assembly deployment position. When the sheath assembly is in the impeller assembly deployment position, a reduction in stiffness is provided between the distal end of the sheath assembly and the impeller assembly.
