    Abstract: A rotor for an axial-flow blood pump has blades projecting outwardly from a hub and channels between the blades. The blades incorporate hydrodynamic bearing surfaces capable of suspending the rotor during operation. The rotor has a configuration which provides superior pumping action and reduced shear of blood passing through the pump. The forwardly facing pressure surfaces of the blades may include outflow corner surface at their downstream ends. The outflow corner surfaces desirably slope rearwardly and intersect the rearwardly-facing suction surfaces of the blades at outflow ends of the blades.

    Abstract: A mechanical circulatory support device includes an inner housing having an inlet end, an outlet end, and a flow path there between. The flow path defines a longitudinal axis. A volute downstream of the outlet end has an outlet port. A rotor mounted within the inner housing upstream of the volute and configured to rotate about the longitudinal axis is included. The volute includes an inner surface having a minimum radius immediately adjacent the rotor and a maximum radius at the outlet port that is larger than the minimum radius.

    Abstract: An implantable blood pump includes an impeller rotatable about a rotational axis, having a body with a bottom surface at a downstream end and a central opening centered about the axis extending at least partially through the body from the bottom surface. A projecting element, e.g., a shaft, extends from below the bottom surface into or through the opening to support the impeller. The body can be configured to drive a primary downstream blood flow along an exterior of the body to beyond a peripheral edge of the bottom surface, and to provide a secondary downstream blood flow through the opening and along the bottom surface to beyond the peripheral edge, the secondary flow improving washing of a bearing surface.
