Abstract

The present invention relates to a device for actively supporting the flow of body fluids, comprising an artificial flow guide system (10) with an operational area into which a pump (1) is embedded in such a way that it can transport blood from at least one inlet opening (3) situated in the guide system to at least one outlet opening (4) situated in the guide system; a flexible feed hose (5) connected to the flow guide system; an energy or force transmission line (6) which is guided through the interior of the flexible feed hose and which, when the device is in the operational state, transmits energy or force substantially continuously to the pump from a drive unit for the extracorporeal generation of this energy or force.
