Patent number: 10232099Abstract: 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: GrantFiled: June 30, 2017Date of Patent: March 19, 2019Assignee: BERLIN HEART GMBHInventors: Hans-Erhard Peters, Jörg Müller, Kurt Graichen, Peter Nüsser, Manfred Göllner, Andreas Arndt

Patent number: 6742999Abstract: A delivery device for a single- or multiphase fluid having a tubular body for axially guiding the fluid, including a motor stator arranged outside the tubular body and a delivery element arranged within the tubular body, comprising a motor rotor. A rotor gap is formed between the delivery element and the hollow body for allowing the fluid to pass through. Mounting arrangements are fixedly disposed in axial direction on each side of the delivery element within the tubular body. Hub gaps are formed between the delivery element and the mounting arrangement. First permanent magnet bearing elements are disposed in the mounting arrangement and second permanent magnet bearing elements are disposed in the delivery element. The first and the second permanent magnet bearing elements functionally work together and are magnetized in axial direction and have opposite polarity. Position sensors associated with each of the first permanent magnet bearing elements and a stabilizer is disposed around the hollow body.Type: GrantFiled: December 31, 2001Date of Patent: June 1, 2004Assignees: Berlin Heart AG, Forschungszentrum Jülich GmbHInventors: Peter Nüsser, Johannes Müller, Hans-Erhard Peters

Patent number: 6719791Abstract: The invention provides a device for the axial delivery of fluidal mediums, which outer diameter is not or only insignificantly larger than the diameter of the fluid carrying pipe, which reduces to a large extent a shearing and vortexing of the fluid. A device for the axial delivery of fluidal mediums, having a tubular hollow body arrangement, in which delivery area, an impeller (9) with a blading, which can be rotated, is arranged and also has a fluid directional means. A motor (2), at least one impeller (9) which can be rotated, and at least one motor mounting (14) are arranged in a tubular hollow body (1) of the hollow body arrangement. The impeller (9) is connected axially force-fittingly and/or form-fittingly to the motor (2).Type: GrantFiled: December 31, 2001Date of Patent: April 13, 2004Assignee: Berlin Heart AGInventors: Peter Nüsser, Johannes Müller, Hans-Erhard Peters, Norbert Buske, Werner Neumann, Kurt Graichen, Conrad Kauffeldt
