Publication number: 20160303300Abstract: 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.Type: ApplicationFiled: June 24, 2016Publication date: October 20, 2016Inventors: Hans-Erhard Peters, Jörg Müller, Kurt Graichen, Peter Nüsser, Manfred Göllner, Andreas Arndt

Publication number: 20160250402Abstract: A blood pump having an axially tubular inlet, a tangential chamber adjoining the axial inlet and having a substantially radial outlet, with an axial guide body connected to the outlet and/or to the tangential chamber, an impeller supported on the guide body and having an inner surface facing the guide body and an outer surface as well as blading arranged on the outer surface. At least one part region of the guide body projects from the tangential chamber into the inlet, wherein at least one section of the stator transmitting a force onto the rotor is arranged in the part region. The impeller is supported by a hydrodynamic radial bearing in the radial direction.Type: ApplicationFiled: May 10, 2016Publication date: September 1, 2016Inventors: Peter Nüsser, Georg Konstas
