Abstract
Intravascular blood pumps systems and methods of use. The blood pump system includes a catheter portion having a distal blood pump with one or more distal collapsible impellers. The system can include a clean purge fluid pathway to carry clean fluid distally to the blood pump and a purge fluid return pathway to carry return fluid proximally into an external motor and out a proximal end of the motor, and optionally to a waste reservoir.
