AB -  Patients suffering from Hydrocephalus show an increased accumulation of cerebrospinal fluid, which needs to be drained into another body compartment by an implanted shunt. To prevent from over-drainage, which sometimes still occurs despite improvements in shunt technology, a possible future shunt could contain sensors and supervise the ventricular size electrically. This work approaches this and presents the in vitro study of a drainage catheter with integrated bioimpedance evaluation capabilities. Keywords: Hydrocephalus, ventricular bioimpedance spectroscopy, electrode drainage, 2 lateral ventricles parenchyma Introduction Most Hydrocephalus patients suffer from an imbalance between production and resorption of cerebrospinal fluid (CSF), increased ventricles, filled with CSF (Figure 1) resulting in increased intracranial pressure. Depending on the kind of Hydrocephalus, patients can be treated by implanting a shunt with an overpressure valve, which drains CSF from the ventricles into another body compartment, whenever the pressure along the shunt exceeds its opening pressure. The right opening pressure according to the current patient's needs has to be chosen in order to successfully treat him. In the case of under-drainage not sufficient CSF is drained and during over-drainage ventricles can even collapse to so called slit ventricles. In both cases the patient suffers from headache.
