摘要： An extracorporeal system for lung assist includes a housing having a blood flow inlet in fluid connection with a pressurizing stator compartment within the housing. A fiber bundle compartment within the housing is above and in fluid connection with the pressurizing stator compartment via a flow channel formed within the housing and extending from the pressurizing stator compartment to an inlet manifold of the fiber bundle compartment. A blood flow outlet in is fluid connection with an outlet man fold of the fiber bundle compartment. The blood flow inlet extends through the housing parallel to a plane of rotation of an impeller in the pressurizing stator compartment. The blood flow inlet turns to deliver blood into a central portion of the impeller. A has inlet is in fluid connection with the housing and in fluid connection with inlets of the plurality of hollow gas permeable fibers of a cylindrical fiber bundle positioned within the fiber bundle compartment. A gas outlet is in fluid connection with the housing and in fluid connection with outlets of the plurality of hollow gas permeable fibers.

摘要： A blood pump system includes a pump housing and an impeller for rotating in a pump chamber within the housing. The impeller has a first side and a second side opposite the first side. The system includes a stator having drive coils for applying a torque to the impeller and at least one bearing mechanism for suspending the impeller within the pump chamber. The system includes a position control mechanism for moving the impeller in an axial direction within the pump chamber to adjust a size of a first gap and a size of a second gap, thereby controlling a washout rate at each of the first gap and the second gap. The first gap is defined by a distance between the first side and the housing and the second gap is defined by a distance between the second side and the pump housing.

摘要： A blood pump may be provided that includes an inlet, an outlet and a rotor for delivering fluid from the inlet to the outlet, wherein the rotor is suspended within the blood pump by radial passive magnetic forces and axially is preloaded in one direction at least by way of passive magnetic forces so that, during a fluid-delivering rotation of the rotor, the axial thrust of the rotor acts counter to the magnetic attraction acting axially in the direction of the outlet.

摘要： A fluid pump conveys a fluid, such as blood. A fluid channel that is bounded by a channel wall and a rotor arranged in the fluid channel and that is rotatably mounted about a pivot point of the bearing with a mechanical, hydrodynamic and/or hydrostatic, axial and radial bearing. The fluid channel has a spherical section and the rotor has a rotor body and a conveying element that is arranged within the spherical section of the fluid channel and configured to generate a substantially spherical rotational area of the rotor. The spherical center of the spherical section of the fluid channel and the spherical center of the spherical rotational area substantially coincide with the pivot point so that a minimum distance between the rotor and the channel wall is maintained in the spherical section upon a tilting of the rotor.
