Claim 0:
1. A catheter pump system comprising:
a catheter assembly having a proximal end, a distal end, and an elongate body extending therebetween, the elongate body defining a lumen;
an impeller assembly configured to translate axially relative to the elongate body of the catheter assembly, the impeller assembly further configured to be extended from the lumen of the elongate body toward an extended position and retracted into the lumen of the elongate body toward a retracted position;
a console-driven motor assembly coupled with the catheter assembly, the motor assembly including a rotor disposed radially within a stator assembly, and a flow diverter at least partially disposed radially between the stator assembly and the rotor, the flow diverter having an inlet coupled to the catheter assembly to receive fluid from the catheter assembly into the flow diverter, and
a priming apparatus including a primer housing and a gas permeable membrane, wherein:
the primer housing is configured to be disposed around the elongate body and over the impeller assembly near the distal end of the catheter assembly when the impeller assembly is in the extended position, and
the priming apparatus is configured to receive a liquid that causes a gas contained by the impeller assembly to be expelled through the gas permeable membrane prior to insertion of the impeller assembly in a lumen of a human body.
