Brief Summary:
The purpose of this clinical investigation is to determine the safety and feasibility of detecting acoustic signals related to blood supply in subjects with acute large vessel occlusion (LVO) stroke by using the SONAS® device.

Condition or disease Intervention/treatment Phase
Stroke, Acute Device: SONAS® Ultrasound Device Not Applicable

Detailed Description:
This clinical investigation will assess the performance of the SONAS® device in subjects with acute stroke admitted to the emergency department or stroke unit within 24 hours of symptoms onset and confirmed occlusion of either the proximal middle, distal M1-segment cerebral arteries, or distal internal carotid arteries (including carotid-T occlusion) by cerebral magnetic resonance imaging (cMRI) or cerebral imaging computed tomography (cCT), including perfusion weighted (pw) imaging sequences, will be considered for the investigation.

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: Experimental:Diagnostic
Diagnostic Test: SONAS® Ultrasound Device
 Device: SONAS® Ultrasound Device
The SONAS® Ultrasound Device is intended for non-invasive transcranial ultrasound and used with a commercially approved contrast agent (e.g., Lumason®/SonoVue®).


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Assessment of Brain Perfusion [ Time Frame: 24 hours ]
    Measurement of the kinetic parameter time to peak (TTP) in the right and left-brain hemisphere during the SONAS® test

  2. Comparison [ Time Frame: 7 days ]
    Comparison between SONAS® versus cMRI or cCT generated intra-individual differences in the parameter TTP in the right and left-brain hemisphere

  3. Assessment of Adverse Events [ Time Frame: 72 hours ]
    Frequency, severity, relationship (to device, contrast agent, or procedure), and outcome of AEs Frequency, severity, relationship (to device, contrast agent, or procedure), and outcome of AEs Frequency, severity, relationship (to device, contrast agent, or procedure), and outcome of AEs
