Outcome Measures
Primary Outcomes (1)
Number of Participants With Device Related Adverse Events
Count the number of participants with device related adverse events
2-3 days, at subject exit (variation of subject exit date depended on when subject obtained their radiology imaging to confirm ischemic stroke)
Study Arms (2)
Subjects with Stroke Symptoms
Suspected stroke subjects that present to hospital with stroke symptoms and are evaluated for stroke
Normal Cohort
Subjects that are not being evaluated for stroke and are confirmed to have no cerebrovascular disease
Interventions
Non-invasive device designed to detect pressure signals from the skull to aid in the diagnosis of ischemic stroke.
Eligibility Criteria
Subjects with stroke symptoms that are being evaluated for stroke or healthy subjects that have no cerebrovascular disease and are not being evaluated for symptoms of stroke.
You may qualify if:
- Symptoms consistent with stroke with known onset \< 12 hours prior to enrollment and planned recording with the Nautilus NeuroWave System
- Suspected pathology of following vessels: internal carotid artery, ACA, MCA, PCA, basilar or other anterior or posterior cerebral vessels or normal anatomy
- Subject is planned to undergo standard stroke triage imaging protocol
- Able to understand and provide signed informed consent, or have a Legally Authorized Representative willing to provide informed consent on subject's behalf
You may not qualify if:
- Known to meet hospital criteria for brain death
- Not a candidate for CT, MRI
- unknown time of stroke symptom onset.
- Psychologically unstable and not able to cooperate
- Not suitable for participation in this study in the opinion of the Investigator
