    Abstract: Fluid pump systems for use in an open loop or closed loop system driven by a motor that does not impede the flow of fluid being pumped are disclosed. A first fluid pump system includes an in-line direct drive motor. The rotor (46, 48) and stator (44) of the motor are positioned about an axis of fluid flow so as not to impede the fluid flow. A second fluid pump system includes an off-line indirect drive motor. The fluid being pumped is driven by an impeller (56) coupled to the inside wall surface of a rotatable member (50) and the outside wall surface of the rotatable member is driven by a motor external to the fluid flow. The motor parts (46, 48) are fully integrated with the pump rotor (56) to drive the pump, therein reducing the number of component requirements, and increasing pump efficiency.

    Abstract: A blood pump (500) preferably has a magnetically suspended rotor (502) that rotates within a housing (506). The rotor (502) may rotate about a stator (504) disposed within the housing. Radial magnetic bearings (560) may be defined within a stator (504) and a rotor (502) in order to suspend the rotor (502). The radial magnetic bearings (560) may be passive magnetic bearings that include permanent magnets disposed within the stator and the rotor or active magnetic bearings. The pump (500) may further include an axial magnetic bearing (562) that may be either a passive or an active magnetic bearing. A motor stator (508) that drives the rotor may be disposed within the housing in order to more easily dissipate heat generated by the motor stator (508). A primary flow path (552) is defined between the stator (504) and the rotor (502), and a secondary flow path (552) is defined between the stator (504) and the rotor (502). Preferably, a substantial majority of blood passes through the primary flow path (550). The secondary flow path (552) is large enough so that it provides adequate flushing of the secondary flow path (552) while being small enough to permit efficient operation of the radial magnet bearings (560) across the secondary path (552).
