Zusammenfassung:	A mechanical circulatory support device for stabilizing a patient after cardiogenic shock comprises a heart pump, including a catheter body and an impeller operative to increase blood flow and stabilize the patient when the impeller is rotated at a predetermined speed. The impeller includes a hub having a circumference and a plurality of blades, each of the plurality of blades respectively having a fixed end joined to the circumference of the hub. The plurality of blades are transitionable between a stored position folded against the hub and a deployed position extending radially outwardly from the hub. The stored position is dimensioned for an insertion of the impeller through a portion of a vascular system of the patient to a heart chamber. Each of the fixed ends of the plurality of blades respectively extends helically around the circumference of the hub to complete a wrapping angle between about 150 degrees and about 220 degrees.
