  • Patent number: 9731056
    Abstract: A blood pump has a hollow body in which an impeller with a spiral blading produces an axial propulsion of blood along the impeller, as well as an at least partly actively stabilized magnetic bearing device and a hydrodynamic bearing device for the impeller. The impeller may be set into a rotation about a rotation axis of the impeller with a motor stator located outside the hollow body. The hollow body has an inlet for the flow of blood into the hollow body in an inflow direction which is essentially parallel to the rotation axis, and an outlet for the outflow of the blood out of the hollow body in an outflow direction which is offset to the rotation axis of the impeller to produce a non-zero outflow angle (?) between the inflow direction and the outflow direction. A total artificial heart can be formed from two such blood pumps.

  • Publication number: 20170021074
    Abstract: The invention relates to an implantable pump system for delivering blood within the body of a patient, with a blood pump which delivers a fluid in an axial direction and comprises a rotatingly drivable rotor as well as a pump casing surrounding the rotor, as well as a support tube, in which the pump casing is arranged and held, wherein an annular gap is formed between the support tube and the pump casing. An almost physiological blood flow is rendered possible in this manner, by way of the combination of a flow through the pump casing on the one hand, and the annular gap on the other hand.
