摘要: A blood pump (20) includes a stator assembly comprising a motor stator (52), a fluid inlet (24), and a fluid outlet (26). A rotor assembly includes a motor rotor (54) and an impeller (40) rotatable about an axis (44) to move fluid from the inlet (24) to the outlet (26). An outflow sheath (300) directs the flow along the outside of the pump (20).

摘要: A blood pump (26) includes a stator assembly (122) that includes a motor stator, a fluid inlet (24), and a fluid outlet (26). A rotor assembly (120) includes a motor rotor (54) and an impeller (40) rotatable about an axis (44) to move fluid from the inlet (24) to the outlet (26). A permanent magnet radial bearing (100) supports the rotor assembly for rotation about the axis (44). The radial bearing (100) includes a permanent magnet radial bearing stator (106) fixed to the stator assembly (122) and a permanent magnet radial bearing rotor (108) fixed to the rotor assembly (120). The radial bearing (100) is configured such that the radial bearing stator magnets (106) and the radial bearing rotor magnets (108) are axially offset from each other when the pump is at rest.

摘要: A blood pump (26) includes a stator assembly including a fluid inlet (24) and a fluid outlet (26). A rotor assembly (120) includes an impeller (40) rotatable about an axis (44) to move fluid from the inlet (24) to the outlet (26). A motor (50) imparts rotation of the impeller (40) about the axis (44). The motor (50) includes a motor stator (52) fixed to the stator assembly (122), a motor rotor (54) fixed to the rotor assembly (120), and a radial motor gap (34) between the stator (52) and the rotor (54). The pump (20) is configured to direct a mixed blood flow from the fluid inlet (24) to the fluid outlet (26) and a wash flow through the motor gap (34).
