Sensor technology for telemetric pressure measurement

For hydrocephalus patients treated with a shunt, measuring intracranial pressure can provide important information to guide the course of treatment in the appropriate direction.*

The M.scio is the logical further development of the SENSOR RESERVOIRS. It is a long-term implant that can be integrated into the shunt system for simple, non-invasive telemetric pressure measurement. The M.scio thus allows conclusions to be drawn about the functional activity of the shunt system.

  • Theranostic system for optimized patient management
  • Reduction of shunt revisions
  • security in shunt function control
  • Improved patient outcome through detailed pressure curves
  • High sampling rate of up to 44 Hz
  • Stable long-term implant with long life time
  • Reliable measured values thanks to minimum drift of < 1 cmH2O/year
  • Small implant in four variants for individual treatment requirements
  • Puncturability of the membrane* enables verification of the pressure value (*domed versions)
  • simple telemetric pressure measurement in real time
  • MRI-compatible up to 3 Tesla


With the M.scio the pressure in a shunt system can be measured and evaluated non-invasively and the result can be included in the treatment options. The M.scio enables a functional check of the shunt system and localization of any shunt occlusions.
The pressure measurement itself is performed by means of the measuring cell located inside the M.scio.

The electronics for pressure measurement is reduced to a minimum by the titanium housing of the measuring cell against external, negative influences that could impair its function - for a high functional reliability and a long service life.

The housing of the M.scio consists of the biocompatible polymer PEEK. The materials used are of very high quality and have been tested and standardized for use as implant materials. The catheters used are made of silicone and are latex-free.

The M.scio is available in four versions: dome-angled, flat-angled, dome-inline and flat-inline. Both "dome" variants fulfill the characteristics of a conventional reservoir due to their puncturability and pumpability in addition to pressure measurement and function control of the shunt system.



Reader Unit Set

The measured values of the M.scio can be read out by the treating physician using the Reader Unit Set. The pressure values are shown on the display in real time and automatically saved with date and time on an SD card. For a later detailed analysis, the data and curves can be accessed again with the Reader Unit Set and evaluated for further processing on the computer, e.g. in MS Excel.

With the Reader Unit Set, the measured values of the M.scio and SENSOR RESERVOIRS can be read out. 



With the individual measurement, the pressure value measured at a point is displayed as an individual measured value.
The measuring unit of the pressure value can be selected in the settings.


During the continuous measurement, sequential individual measurements are performed and the recorded measured values are displayed as a curve. The interval between the individual measurements can be adjusted in the settings in the range from 1 to 300 seconds.


With the quick measurement, sequential individual measurements are recorded at a high sampling rate (max. 44 measurements per second) and displayed as a curve.

Quality Reference

A first user survey within the scope of the clinical follow-up (PMCF study) for the predecessor SENSOR RESERVOIR impressively proves the long-term stability and quality of the telemetric MIETHKE pressure sensors.

Loadable data size:

high feedback rate

This survey was conducted in 2019 and contains feedback on a total of 284 implanted MIETHKE pressure sensors.

High survival rate:

stable long-term implant

95% (270) of the MIETHKE pressure sensors were still implanted in the patients at the time of the survey - without malfunction, many of them for more than three years.

High user satisfaction:

helpful product

100% of the users of the MIETHKE pressure sensors have evaluated it as a helpful product and an advantageous addition in the treatment of hydrocephalus.
