1. A blood pump for supporting cardiac performance, comprising:
a stent-like housing having a first axial end and a second axial end;
a pump rotor mounted rotatably in the housing;
a flexible drive shaft configured to be coupled to a motor to drive the pump rotor to rotate; and
a flow directing arrangement arranged downstream of the pump rotor in order to selectively direct the blood conveyed by the pump rotor alternately to the first axial end and or to the second axial end of the stent-like housing while maintaining a direction of rotation of the pump rotor, the first axial end being opposite the second axial end;
wherein blood is sucked in on an intake side of the pump rotor through an intake tube of the blood pump and is ejected on a discharge side of the pump rotor.
