The present invention provides an intravascular blood pump comprising an impeller housing and/or impeller blade(s) that may be expandable and collapsible. The blade(s) and/or impeller housing may be biased to expand or may be expanded by centrifugal forces generated during rotation of the impeller and blades with an operatively connected rotational motor.
