Summary

This study is a multi-center, prospective, single-arm, non-significant risk (NSR) device study in which up to 150 evaluable subjects with suspicion of embolic stroke of undetermined source (ESUS) will be evaluated with NB-IS TCD and standard of care TTE to screen for right to left shunt (RLS) or patent foramen ovale (PFO). Additionally, up to 150 evaluable subjects will be evaluated with NB-IS TCD and standard of care TEE.

Eligible Conditions
  • Stroke
  • Mini Stroke
  • Atrial Septal Defect
  • Patent Foramen Ovale

Timeline

Screening ~ 3 weeks
Treatment ~ Varies
Follow Up ~1 to 60 days after subject receives robotic transcranial doppler ultrasound bubble exam
This trial's timeline: 3 weeks for screening, Varies for treatment, and 1 to 60 days after subject receives robotic transcranial doppler ultrasound bubble exam for reporting.

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Percent Detection of Right to Left Shunt (RLS)/Patent Foramen Ovale (PFO) Using Robotic Assisted TCD (Study Device)
Secondary outcome measures
Percent agreement for detection of clinically significant shunts with robotic TCD vs TTE
Ultrasonography, Doppler, Transcranial
Percent detection of RLS/PFO compared to SOC Transesophageal Echocardiography
