Abstract: A method is provided of controlling a pump including a electrical motor coupled to a rotor which carries first and second impellers at opposite ends thereof. The method includes: (a) driving the rotor using the motor, so as to circulate fluid from the first impeller through a first fluid circuit, the second impeller, a second fluid circuit, and back to the first impeller; (b) determining a resistance of the first fluid circuit, based on a first motor parameter; (c) determining a flow rate through the first fluid circuit based on a second motor parameter; and (d) varying at least one operational parameter of the pump so as to maintain a predetermined relationship between the flow rate and the resistance of the first fluid circuit.

Abstract: In a centrifugal flow blood pump, usable in left ventricular assist applications, blood is pumped from an inlet (16) to an outlet (22) by a primary impeller (18). A portion of the blood that enters the pump follows a secondary channel (24) where a secondary impeller (70) routes the blood to lubricate a bearing between an impeller assembly (14) and a post formed by a component of the pump housing. The unique shape of the secondary impeller (70) prevents blood stagnation and provides for a well-washed fluid bearing.

Abstract: A pump includes a housing, a stator supported in the housing, and a rotor assembly including a rotor supported in the housing for rotation relative to the stator about an axis. The stator includes a stator core, a first lamination wound around an axial portion of the stator core, and a second lamination wound around a second axial portion of the stator core. The first and second laminations are spaced from each other along the length of the stator core. The rotor includes a rotor core, a first magnet assembly that extends around an axial portion of the rotor core, and a second magnet assembly that extends around a second axial portion of the rotor core. The first and second magnet assemblies are spaced from each other along the length of the rotor.

Abstract: A pump (10) includes a housing, a stator (20) supported in the housing, and a rotor assembly (30). The rotor assembly (30) includes a rotor (32) supported in the housing for rotation relative to the stator (20) about an axis (12). The rotor assembly (30) also includes a first impeller (34) operatively coupled to a first axial end of the rotor (32) for rotation with the rotor about the axis (12). The rotor assembly further includes a second impeller (36) operatively coupled to a second axial end of the rotor (32), opposite the first axial end, for rotation with the rotor about the axis (12). The rotor assembly (30) is movable along the axis (12) relative to the housing to adjust hydraulic performance characteristics of the pump (10).

Abstract: A hot wire igniter for igniting a gaseous or atomized fuel is disclosed. The coil of the hot wire igniter is formed from a thin high temperature, iron, chromium, aluminum alloy having a center section that is tightly wound. The coil turns initially do not touch one another and each end of the coil is attached to a rod that is received within an insulator member. The rods are connected to a power source. The coil portion of the hot wire igniter is received within a gas collector box which is attached to the burner to be ignited. Application of the power source to the lead-in rods causes the coil of wire to reach a temperature in excess of the ignition temperature of the fuel mixture which surrounds same causing the ignition of the mixture.
