SENSOR TECHNOLOGY

FOR TELEMETRIC MEASUREMENT OF INTRACRANIAL PRESSURE

Hydrocephalus and subarachnoid hemorrhages may be associated with a life-threatening increase in intracranial pressure (ICP). Determining the ICP is an important requirement for proper application of ICP-lowering measures.10 To date, there is no way to adequately determine intracranial pressures based on symptoms or imaging methods alone.11,12

In addition to measurement for initial diagnosis, it may be necessary to monitor intracranial pressure repeatedly over a period of years to ensure the desired therapeutic outcome. The information gathered can help prevent time-consuming and costly examinations and hospitalizations, thus improving patient well-being.2,4,5

The M.scio is a long-term implant for simple, non-invasive telemetric measurement of intracranial pressure.

 

From diagnosis to therapy

The M.scio can be used for diagnosis as well as for therapy support.

It can be implanted to determine intracranial pressure for diagnostic purposes.3 Moreover, the M.scio can also be integrated into a shunt to determine the ICP in the shunt.2-4 This allows conclusions to be drawn about the functionality of the shunt system and may help to steer treatment in a positive direction.2

M.scio®

FUNCTIONALITY

The M.scio makes it possible to measure and evaluate intracranial pressure non-invasively. The results can then be incorporated into diagnostic and therapeutic decisions. It is an advanced version of the SENSOR RESERVOIR.


Pressure is measured via a measuring cell located inside the M.scio. The electronics for pressure measurement are protected 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 is made of the biocompatible polymer PEEK. The materials used are of the highest-quality and have been tested and standardized for use as implant materials. The catheters are made of silicone and are latex-free.

The M.scio is available in four variants: dome-angled, flat-angled, dome-inline, and flat-inline. Both “dome” variants fulfill the characteristics of a conventional reservoir in addition to intracranial pressure measurement. This means they allow therapeutic pressure relief through withdrawal of cerebrospinal fluid (CSF), diagnostic sampling of CSF, administration of fluids, and verification of pressure readings.

 

 

 

Reader Unit Set

The pressure values of the M.scio can be read out by the attending physicians with the help of the Reader Unit Set. The measured values are displayed and automatically stored with date and time on an SD card. For later detailed analysis, the data and curve progressions can be recalled with the Reader Unit Set and evaluated on a PC with ICPicture for further processing for research purposes.




 

measuring modes

Three measuring modes are available for recording pressure values with the Reader Unit Set.

SINGLE MEASUREMENT

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

CONTINUOUS MEASUREMENT

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

FAST MEASUREMENT

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

Quality Reference

A 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 pressure sensors.

RELEVANT DATA SIZE:
HIGH FEEDBACK RATE

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

HIGH SURVIVAL RATE:
STABLE LONG-TERM IMPLANT

95% (270) of the 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 pressure sensors have evaluated it as a helpful product and an advantageous addition in the treatment of hydrocephalus.
