Intravascular pump with expandable distal region

A blood pump having a housing, inlet apertures, outlet apertures and further comprising:

• an impeller assembly comprising at least a rotatable rotor within the housing;
• a collapsible and expandable region disposed distal of the impeller assembly;
• a non-expandable region proximal of the collapsible and expandable region, wherein the collapsible and expandable region comprises a distal portion of the housing comprising the inlet apertures deformed to invert proximally within itself to achieve an inverted collapsed configuration and adapted to translate through a delivery catheter, and wherein the distal portion of the housing is adapted to passively evert to achieve an expanded configuration when the distal portion of the housing comprising the inlet apertures is translated distally out of the delivery catheter and into a target location within a patient's body.
