Abstract
A fluid pump device changeable in diameter is provided. The device has a pump housing which is changeable in diameter and with a rotor which is changeable in diameter. The device has at least one delivery element for fluid, as well as a drive shaft on which the rotor is rotatably mounted. A bearing arrangement is arranged on the drive shaft or its extension, at the distal end of the drive shaft behind the rotor seen from the proximal end of the drive shaft. The bearing arrangement has struts, which elastically brace between a hub of the bearing arrangement and the pump housing.
