Abstract: A pump configured for implantation into a human heart or vascular system, the pump comprising: an elongate housing having first and second ends, an internal surface, a first inlet for blood disposed between the first and second ends and an outlet spaced longitudinally from the first inlet, the first inlet and the outlet defining a primary flow path through the housing; a rotor disposed within the housing and spaced from the internal surface to define a clearance therebetween; an impeller coupled to the rotor for impelling blood from the first inlet to the outlet of the housing; and a second inlet for blood within the housing fluidly coupled to the clearance between the rotor and the housing to define a secondary flow path through the clearance.
