A hydrocephalus shunt arrangement for draining cerebrospinal fluid (CSF) in a patient includes a ventricle catheter, a first drainage line, a control valve, a second drainage line, and an intracranial device. The ventricle catheter is inserted into a ventricle space of the brain of a patient. The first drainage line is connected to the ventricle catheter. The control valve is connected to the first drainage line and controls the drainage of CSF from the cranium of the patient through the second drainage line into a drainage area inside an abdominal cavity of the patient. The intracranial device is implanted under the skin of the patient in or at the cranium and connected to the ventricle catheter or the control valve. The intracranial device includes a corrugated metal membrane covering a chamber disposed within a rigid housing. The control valve produces a desired, controlled, drainage of excess CSF.
