  Purpose
The purpose of the study is to determine the sensitivity, specificity and predictive values of the Jan Medical NeuroWave System in detecting moderate and severe vasospasm in comparison to Trans Cranial Doppler(TCD).

Cerebral Vasospasm Device: Nautilus NeuroWave Device: Transcranial Doppler (TCD)

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Crossover Assignment
Masking: Double (Participant, Outcomes Assessor)
Primary Purpose: Diagnostic
Official Title: A Non-Randomized, Non-Significant Risk Study Comparing the Nautilus NeuroWaveTM System to Transcranial Doppler as an Aid to Diagnosing Vasospasm

Further study details as provided by Jan Medical, Inc.:

Primary Outcome Measures:
  • Sensitivity and specificity as a diagnostic aid in detecting vasospasm in subarachnoid hemorrhage [ Time Frame: 12 months ]
    Outcome determine Upon completion of study and unmaksing


Secondary Outcome Measures:
  • Location of vasospasm in the caranium [ Time Frame: 12 months ]
    outcome determine upon completion of study and unmasking

  • Incidence of device related adverse events [ Time Frame: 12 months ]

Enrollment: 72
Study Start Date: January 2012
Study Completion Date: July 2015
Primary Completion Date: March 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Subjects without Vasospasm
Transcranial Doppler (TCD) will be used to evaluate if subject has a vasospasm. Intervention with Nautilus NeuroWave recording to obtain baseline status.
Device: Nautilus NeuroWave

The Nautilus NeuroWave device will be utilized on subjects with sub-arachnoid hemorrhage that undergo TCD measurements to diagnose Vasospasm. A recording will be obtained using the device each time a TCD measurement is made.

In this intervention, patients are recorded using the Nautilus Neurowave device.

Device: Transcranial Doppler (TCD)
Subjects with sub-arachnoid hemorrhage undergo TCD measurements to diagnose Vasospasm. Patients that were detected to have a vasospasm using TCD will also be classified as having mild, moderate and severe vasospasm.
Experimental: Subjects with Vasospasm

Transcranial Doppler (TCD) will be used to evaluate if subject has a vasospasm. If confirmed by TCD, the degree of vasospasm will also be evaluated and classified as mild, moderate and severe Vasospasm.

Intervention with Nautilus NeuroWave recording to obtain recordings with mild, moderate and severe Vasospasm.

Device: Nautilus NeuroWave

The Nautilus NeuroWave device will be utilized on subjects with sub-arachnoid hemorrhage that undergo TCD measurements to diagnose Vasospasm. A recording will be obtained using the device each time a TCD measurement is made.

In this intervention, patients are recorded using the Nautilus Neurowave device.

Device: Transcranial Doppler (TCD)
Subjects with sub-arachnoid hemorrhage undergo TCD measurements to diagnose Vasospasm. Patients that were detected to have a vasospasm using TCD will also be classified as having mild, moderate and severe vasospasm.
