Claim 10:
11. A method for removing air from an impeller assembly of a catheter pump system prior to insertion of the catheter pump system in a blood lumen of a human body, the method comprising:
providing a priming apparatus near a distal end of a catheter assembly, the priming apparatus including:
a primer housing having a distal end, a proximal end, and an elongate body extending therebetween, the primer housing configured to be disposed around the elongate body;
a sealing cap coupled to the proximal end of the primer housing; and
a gas permeable membrane;

inserting the distal end of the catheter assembly through the sealing cap of the priming apparatus;
coupling a console-driven motor assembly to 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;
extending an impeller assembly contained within a central lumen of the catheter assembly out of the central lumen into the primer housing;
adding a liquid to the primer housing; and
retracting the impeller assembly into the central lumen of the catheter assembly.
