The implant works with a catheter, with a first free end led to a point in the brain, where excessive fluid can be drained off. A second free end is led in to the body, where the excessive fluid can be received. A valve is fitted in the course of the catheter. A measuring unit is connected to the sensor, which measures the amount of fluid per time unit, flowing through the catheter. The measuring unit for the adjustment and/or the monitoring of the valve, works in conjunction with an adjusting unit and/or with a control unit located outside the body. The through flow sensor consists of a selected flow resistance and a pressure sensor. The pressure sensor measures the pressure drop at the resistance
