    Abstract: The invention relates to a device (105) for determining a cardiac output for a cardiac assist system (100), wherein the device (105) comprises a support structure (115) and a sensor device (120). The support structure (115) comprises at least one brace (125) and a connection section (130) for connecting the device (105) to an element (110, 112) of the cardiac assist system (100). The at least one brace (125) is connected to the connection section (130) and can be folded away from the element (110, 112). The sensor device (120) is coupled to the at least one brace (125) and configured to sense a blood stream.

    Abstract: The invention relates to a rotor bearing system (1). Said system comprises a housing (80) in which a first permanent magnet (30) is mounted such that it can rotate about a first axis (105). A rotor (70) for conveying a liquid comprises a second hollow-cylindrical permanent magnet (40), which is mounted such that it can rotate about a second axis. The first permanent magnet (30) and the second permanent magnet (40) overlap axially at least partially, wherein the first permanent magnet (30) is disposed offset relative to the second permanent magnet (40). In the axial overlap region (160) of the first permanent magnet (30) and the second permanent magnet (40), the housing (80) is positioned between the two permanent magnets (30, 40). A first bearing (20) is configured for the relative axial positioning of the rotor (70) and the housing (80) with respect to one another and for receiving an axial force resulting from the arrangement of the first permanent magnet (30) and the second permanent magnet (40), and a second bearing (10) and a third bearing (90) are configured for receiving radial forces and for positioning the axis of rotation of the second permanent magnet (40).
