1. A heart support system, comprising:
an inlet tube extending in a longitudinal direction, the inlet tube comprising an inlet opening positioned in a distal portion of the inlet tube and configured to receive blood into the heart support system;
a pump housing connected to a proximal end of the inlet tube and extending proximally in the longitudinal direction and downstream from the inlet tube, the pump housing comprising:
a lateral surface comprising at least one outlet opening configured to receive discharged blood therethrough from the pump housing; and
a stator vane device arranged in the region of the at least one outlet opening, the stator vane device comprising at least one stator vane configured to unfold from a folded-in state to a flow guiding state after the inlet tube and pump housing section are inserted into a blood vessel using a catheter, wherein the at least one stator vane is configured to project radially or obliquely from the lateral surface of the pump housing in the flow guiding state;
an impeller positioned at least partially lateral to the at least one outlet opening within the pump housing and having an axis of rotation parallel to the longitudinal direction of the pump housing; and
a drive device positioned on a side of the impeller opposite the inlet tube and configured to drive the impeller.
