Abstract: A mechanical circulatory support device. The mechanical circulatory support device includes an inner casing defining a fluid flow path, the fluid flow path defines a longitudinal axis. A rotor is mounted within the fluid flow path and configured to rotate about the longitudinal axis. A housing is included, the inner casing and the rotor being substantially disposed within the housing. The housing having a cross-sectional shape in a plane transverse to the longitudinal axis which decreases in thickness extending from a medial position to opposite lateral positions.

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.

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 blood pump casing including a unitary body. The unitary body defines an inlet chamber extending along a first axis and having a first radius perpendicular to the first axis. A transition chamber is connected to the inlet chamber and has a wall extending in a circumferential direction around the first axis, the wall has a major radius and a minor radius from the first axis, the major radius being greater than the first radius. A post extends from the transition chamber into the inlet chamber along the first axis, the post tapers in the direction around the first axis toward the inlet chamber. An outlet is connected to the transition chamber and extends along a second axis transverse to the first axis.
