Last updated: January 29, 2017
Last verified: January 2017
To assess the feasibility of a new neuromonitoring system (NeMoSystem including NeMo Probe and NeMo Patch) and the accuracy of the measurement values (cerebral blood flow (CBF); cerebral blood volume (CBV)) obtained.

Condition Intervention
Subarachnoid Hemorrhage
Optical Imaging
Device: NeMo Patch and NeMo Probe

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: No masking
Primary Purpose: Diagnostic
Official Title: A New Multi-parameter Neuromonitoring System to Save Patients' Lives in Stroke and Brain Injury

Further study details as provided by NeMoDevices AG:

Primary Outcome Measures:
  • To assess the feasibility of the neuromonitoring system and the accuracy of the measurement values. [ Time Frame: Day 28 after removal of medical device ]


    User acceptance: For NeMo Probes in comparison to conventional probes for intracranial pressure (ICP-) monitoring; for NeMo Patch in comparison to patches for electroencephalography (EEG) monitoring.

    Detailled evaluation of user acceptance:

    • Incidence of concerns of users in relation to the installation, function and removal of the NeMo System (= NeMo Probe, NeMo Patch, NeMo Control Unit and NeMo Software pre-installed on a Medical PC)
    • User-friendliness with a 3-graded scale (equal, better, worse) compared to conventional devices

    Accuracy of measurements:

    -Patients: Results from repeated measurements of mean transit time of ICG (mttICG), cerebral blood flow (CBF) and cerebral blood volume (CBV)

    Safety parameters:

    Incidence of complications (infections, brain tissue damage, haemorrhage) compared to historical series (patches for EEG and for BIS measurements; conventional probes for ICP monitoring)

Secondary Outcome Measures:
  • To demonstrate the ability of the neuromonitoring system to detect secondary ischemic events in patients with severe subarachnoid haemorrhage (SAH) or severe traumatic brain injury (TBI). [ Time Frame: Day 28 after removal of medical device ]
    Results concerning sensitivity and specificity to detect symptomatic vasospasm in patients with subarachnoid hemorrhage (SAH) (correlation of events with CBF values < 15 ml/100g/min with defined criteria for vasospasm) Results concerning sensitivity and specificity to detect secondary infarctions and critical ICP values in TBI patients (correlation of events with CBF values < 15 ml/100g/min with defined criteria for secondary infarction) Results from repeated measurements for the difference between measurement values obtained with the NeMo Patch and the NeMo Probe, quantified with mathematical models

Estimated Enrollment: 80
Study Start Date: January 2013
Estimated Study Completion Date: March 2018
Estimated Primary Completion Date: December 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
NeMo Patch and NeMo Probe
TBI and SAH patients, one arm
Device: NeMo Patch and NeMo Probe
A plaster based patch (NeMo Patch) and a combined probe for ICP monitoring and near infrared spectroscopy (NIRS) are applied as sensors. Data are collected by a NIRS instrument (NeMo Control Unit)
