System for actively supporting the flow of body fluids

A device for actively supporting the flow of body fluids, comprising:

• a) an artificial flow guide system with a surrounding wall and an operational area into which a pump is embedded in such a way that the pump bears against the wall of the flow guide system with complete sealing and can transport body fluid from at least one inlet opening situated in the guide system to at least one outlet opening situated in the guide system;
• b) a flexible feed hose connected to the flow guide system;
• and
• c) an energy or force transmission line extending through an interior of the flexible feed hose and transmitting energy or force substantially continuously to the pump from a drive unit,
• wherein the pump is a miniature gear pump comprising two rotors, wherein one rotor forms an axially directed sealing line with the other rotor.
