The invention relates to a stator vane device (105) for guiding the flow of a fluid flowing out of an outlet opening (110) of a heart support system (100). The stator vane device (105) has at least one stator vane (115), which can be connected to the heart support system (100) and arranged in the region of the outlet opening (110). The at least one stator vane (115) is formed such that it can be folded together to take an insertion state of the heart support system (100) and can be unfolded to take a flow guiding state. The at least one stator vane (115) is designed to project radially or obliquely from the heart support system (100) in the flow guiding state.
