Claim 7:
8. A catheter pump assembly, comprising:
an elongate catheter body having a distal end insertable into a patient, and a proximal end opposite the distal end; and
a motor assembly, comprising:
an electric motor comprising a rotor configured to rotate about a longitudinal axis of a catheter;
a mount oriented in a plane normal to the longitudinal axis;
a drive magnet operably coupled to the rotor and configured to translate along the longitudinal axis relative to the mount;
a driven magnet coupled to a drive shaft extending longitudinally through the catheter, the driven magnet electromagnetically coupled to the drive magnet, wherein at least one of i) the drive magnet is cylindrical and includes poles oriented along the longitudinal axis, and ii) the driven magnet is cylindrical and includes poles oriented along the longitudinal axis; and
a flow diverter coupled to the proximal end of the elongate catheter body, the flow diverter comprising the driven magnet mechanically coupled to the drive shaft extending through the elongate catheter body.
