    Abstract: The invention generally relates to improved medical blood pump devices, systems, and methods. For example, blood pumps may be provided that include a housing defining a blood flow path between an inlet and an outlet. A rotor may be positioned in the blood flow path. A motor stator may be driven to rotate the rotor to provide the blood flow through the pump. Axial and/or tilt stabilization components may be provided to increase an axial and/or tilt stabilization of the rotor within the blood flow path. In some embodiments, biasing forces are provided that urge the rotor toward a bearing component. The biasing force may be provided by adjusting drive signals of the motor stator. Additionally, or alternatively, one or more magnets (e.g., permanent/stator magnets) may be provided to bias the rotor in the upstream and/or downstream direction (e.g., toward a bearing (chamfer, step, conical), or the like).

    Abstract: A blood pump includes a housing and a rotor within the housing configured to rotate along an axis. The rotor may include a hub, the hub having regions with blades and regions without blades. The regions without blades may have a constant outer diameter and may extend along at least one fourth the length of the hub. The regions with blades may have an increasing outer diameter. Blades may be disposed on a downstream end region of the hub and extend downstream of the hub. Blades may begin approximately halfway along the axial length of a motor stator located about a hub and extend downstream of the motor stator. Blades may have portions that produce axial fluid flow and radial fluid flow with improved flow characteristics.
