Abstract:
A heart pump including: a housing forming a cavity including: at least one inlet aligned with an axis of the cavity; and, at least one outlet provided in a circumferential outer wall of the cavity; an impeller provided within the cavity, the impeller including vanes for urging fluid from the inlet to the outlet; and, a drive for rotating the impeller in the cavity and wherein a flow path through the pump has a minimal cross-sectional area of at least 50 mm 2 .

Claim (Index 17):
A heart pump according to  claim 1 , wherein:\n a) the impeller includes first and second sets of vanes provided on a rotor body, the rotor being positioned within the cavity to define:\n i) a first cavity portion having a first inlet and a first outlet, the first set of vanes being provided within the first cavity portion so as to define a first pump that provides at least partial left ventricular function; and, \n ii) a second cavity portion having a second inlet and a second outlet, the second set of vanes being provided within the second cavity portion so as to define a second pump that provides at least partial right ventricular function and wherein at least one of:\n (1) the axial position of the impeller determines a separation between each set of vanes and a respective housing surface, the separation being used to control the fluid flows from the inlets to the outlets; and, \n (2) the first and second pumps have respective pump performance curve having different gradients so that a change in rotational speed of the pump causes a change in the relative flows of the first and second pumps; \n \n b) the drive is positioned at a first end of the cavity and includes:\n i) a number of circumferentially spaced permanent magnets mounted in the rotor of the impeller, adjacent magnets having opposing polarities; and, \n ii) at least one drive coil that in use generates a magnetic field that cooperates with the magnetic material allowing the impeller to be rotated; \n c) the pump includes a magnetic bearing for controlling an axial position of the impeller within the cavity and wherein the magnetic bearing is positioned at a second end of the cavity and includes:\n i) first and second annular magnetic bearing members mounted within and proximate a face of the rotor, the first magnetic bearing member being outwardly of the second magnetic bearing member; \n ii) a number of circumferentially spaced substantially U-shaped bearing stators mounted in the housing proximate a second end of the cavity, each U-shaped bearing stator having first and second bearing stator legs substantially radially aligned with the first and second magnetic bearing members respectively; and, \n iii) at least one bearing coil on each bearing stator that generates a magnetic field that cooperates with the magnetic bearing members to thereby at least one of:\n (1) control an axial position of the impeller; and, \n (2) at least partially restrain radial movement of the impeller.
