1. An intravascular pump device, comprising:
a first catheter having a proximal end and a distal end;
a pump housing configured to compress into a compressed state and expand into an expanded state, wherein the pump housing is configured to move within the first catheter and the pump housing elastically expands into the expanded state upon release from the first catheter;
the pump housing having a rotor disposed therein, the rotor comprising a plurality of impeller blades, the impeller blades flexibly attached to a hub and being elastically compressible and automatically elastically expandable, wherein the impeller blades are configured to convey a fluid by a supplied energy; and
a plurality of detection devices, a first detection device arranged on a first impeller blade in a position away from the hub, a second detection device arranged on a second impeller blade adjacent the hub and a third detection device arranged on the housing.
