Abstract: A sensor system is used for measuring, transmitting, processing and displaying a brain parameter. The sensor system has at least one implantable brain parameter sensor with a wireless transmission unit for measuring the brain parameter. At least one receiving unit with an antenna is in wireless signal connection with the latter. At least one data read module is in signal connection with the antenna and a data processing and display device is in turn in signal connection with said data read module. The sensor system also has a head cap or a head hood, on which the receiving unit is fixed to predetermine a relative position relative to the transmitting unit. A sensor system is the result, the use of which remains comfortable for the patient even over a relatively long measuring period.

Abstract: A device (1) is used for measuring brain parameters. This device has a catheter sensor unit (2) which can be implanted distally in a minimally-invasive manner in the parenchyma and/or the ventricles, guided through the cranial bone (4). The sensor unit (2) can be fixed proximally to the cranial bone. For this purpose a proximal circumferential portion of the sensor unit (2) has a self-cutting outer screw thread (5) for fastening the sensor unit (2) to the cranial bone (4). The result is a device which can be fastened in a secure, permanent and at the same time inexpensive manner preventing movement relative to the cranial bone.
