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.
