Abstract

To assure, in the case of an implantable device for determining intracranial pressures, the biocompatibility of the implant in the long term, wherein a pressure measuring device is used, which is operatively connected to a sensor for a telemetric measured value transfer, it is proposed that the pressure measuring device is a microchip, that the microchip is located in a rigid housing, and that the pressure transfer from the outside inwards occurs through a very thin biocompatible membrane, the pressure-dependent movement of which acts on the pressure measuring device via a transfer medium.
