An active magnetic rotor-bearing assembly for conveying a fluid comprising a rotor assembly is disclosed and a bearing assembly for contactless bearing the rotor assembly, where the bearing assembly comprises an even number of electromagnetic units arranged around a central structure each comprising a first salient established by a magnetic material and a permanent magnet providing a first magnetic pole and a coil around the salient, further comprises an inter-yoke with inter-yoke portions connected to the first salient of each electromagnetic unit and being separated from each other by structure spacers, providing a closed first magnetic flux passing the rotor assembly applying a first attractive force further comprising a position stabilizing portion perpendicular to the first attractive force on the rotor-assembly and the coils providing an electromagnetic flux between each first salient and the rotor assembly for applying adaptable axial force and/or tilting torque to the rotor assembly.

The present invention relates to a fluid pump that comprises a housing having an inlet opening for receiving the fluid, an outlet opening for discharging the fluid and enclosing an impeller rotating inside the housing to pump the fluid from the inlet opening to the outlet opening and a motor assembly to drive the impeller. The housing is shaped to establish a single turn volute of 360&#xb0; turn angle providing a first conveying channel located peripherally around the impeller from a fluid entry point at 0&#xb0; turn angle to a fluid exit point at 360&#xb0; turn angle of the single turn volute being connected to the outlet opening. The first conveying channel has a first cross section area in radial direction perpendicular to the rotational plane of the impeller, where a size of the first cross section area increases as a monotonic increasing function of the turn angle between entry point and exit point.

The device for closing openings or cavities in blood vessels, e.g. in veins or in the heart, said device comprises a closing body comprising an outer side having a partial region arranged for blood flow therealong at least in a part of said partial region thereof when said closing body is in its state of use for closing said opening or cavity. Furthermore, the device comprises at least one layer () of biostable nonwoven fiber material, which at least within a partial surface of said partial region of said outer side of the closing body is at least partially in abutment on the closing body.
