Abstract
An adjustable hydrocephalus valve comprising a mechanical brake. The brake can be decoupled by pressing the valve housing percutaneously and allows in this state to adjust the opening characteristics of the valve by rotating externally disposed magnets. In order to detect the adjusted pressure or in order to adjust the pressure, specific adjustment or measuring pin principles are presented which simplify and at the same time improve the respective functions of measuring and adjusting.
