Publication number: 20230321427Abstract: 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.Type: ApplicationFiled: March 13, 2023Publication date: October 12, 2023Applicant: Berlin Heart GmbHInventors: Hendryk Richert, Oliver Peters
