The invention relates to a stator vane device () for guiding the flow of a fluid flowing out of an outlet opening () of a heart support system (). The stator vane device () has at least one stator vane (), which can be connected to the heart support system () and arranged in the region of the outlet opening (). The at least one stator vane () is formed such that it can be folded together to take an insertion state of the heart support system () and can be unfolded to take a flow guiding state. The at least one stator vane () is designed to project radially or obliquely from the heart support system () in the flow guiding state.

The invention relates to a rotor bearing system (). Said system comprises a housing () in which a first permanent magnet () is mounted such that it can rotate about a first axis (). A rotor () for conveying a liquid comprises a second hollow-cylindrical permanent magnet (), which is mounted such that it can rotate about a second axis. The first permanent magnet () and the second permanent magnet () overlap axially at least partially, wherein the first permanent magnet () is disposed offset relative to the second permanent magnet (). In the axial overlap region () of the first permanent magnet () and the second permanent magnet (), the housing () is positioned between the two permanent magnets (). A first bearing () is configured for the relative axial positioning of the rotor () and the housing () with respect to one another and for receiving an axial force resulting from the arrangement of the first permanent magnet () and the second permanent magnet (), and a second bearing () and a third bearing () are configured for receiving radial forces and for positioning the axis of rotation of the second permanent magnet ().

Rotor bearing system

An impeller () for an implantable vascular support system () is provided. The impeller includes an impeller body () having a first longitudinal portion () and a second longitudinal portion () forming a first inner rotor () having at least one magnet encapsulated in the second longitudinal portion (). At least one blade () formed in the first longitudinal portion () is configured to axially convey a fluid upon rotation. A second outer rotor () extends axially and includes at least one magnet. The first rotor () and the second rotor () form a magnetic coupling (). The magnets of the first and second rotor being arranged to partially axially overlap with an axial offset and are entirely radially offset.
