    Abstract: A blood pump apparatus includes a housing having a blood inlet port and blood outlet port, a pump unit including an impeller that rotates within the housing, and an impeller rotational torque generation section. The housing includes a plurality of magnetic members embedded between the impeller and the impeller rotational torque generation section for transmitting a magnetically attractive force generated by the impeller rotational torque generation section to an impeller body. The pump device includes a non-contact bearing mechanism for rotating the impeller without contacting with the inner surface of the housing when the impeller is rotated by the impeller rotational torque generation section.

    Abstract: A flow thru mechanical bearing system can be used in an implantable rotary blood pump that includes a pump housing. An impeller housed in the pump housing can be radially supported by a row of at least three low friction contact points located on an inside bore of the impeller. The impeller may be axially supported by a second mechanical bearing. The second mechanical bearing may provide at least three axial contact points on the top surfaces of the impeller. The impeller is driven by a magnetic coupling which functions mainly to transmit torque to the impeller. Further, in some cases, the magnetic coupling may restrain axial motion of the impeller.

    Abstract: A percutaneous pumping system for providing hemodynamic support to a patient includes a pumping sleeve that defines a lumen extending along the length of the pumping sleeve. The pumping sleeve is configured and arranged for insertion into patient vasculature. At least one rotatable magnet is disposed in the pumping sleeve. The at least one first magnet is configured and arranged to be driven to rotate by a magnetic field generated external to the pumping sleeve. At least one impeller is coupled to the at least one magnet. Rotation of the at least one magnet causes a corresponding rotation of the at least one impeller. An anchoring arrangement is coupled to the pumping sleeve. The anchoring arrangement is configured and arranged to anchor the pumping sleeve at a target pumping location when the pumping sleeve is inserted into patient vasculature.

    Abstract: Various “contactless” bearing mechanisms including hydrodynamic and magnetic bearings are provided for a rotary pump as alternatives to mechanical contact bearings. In one embodiment, a pump apparatus includes a pump housing defining a pumping chamber. The housing has a spindle extending into the pumping chamber. A spindle magnet assembly includes first and second magnets disposed within the spindle. The first and second magnets are arranged proximate each other with their respective magnetic vectors opposing each other. The lack of mechanical contact bearings enables longer life pump operation and less damage to working fluids such as blood.
