    Outcome Measures

    Primary Outcome Measures

    1. Number of Participants With Procedural Success [30 Days]

      Procedural success is defined as acute device success (successful insertion of the ENROUTE NPS and establishment of flow reversal), technical success (deployment of interventional tools) and the absence of a major adverse events (hierarchical stroke/death/myocardial infarction) through 30 days.

    Secondary Outcome Measures

    1. Number of Participants Experiencing Major Adverse Event [30 days]

      Secondary endpoints include the 30-day rate of hierarchical stroke, death or myocardial infarction, the rate of hierarchical stroke, death or myocardial infarction by symptom status, the rate of cardiac death and the rate of neurological death.

    2. Number of Participants With Acute Device Success [2 hours (periprocedural)]

      Acute device success is defined as the ability to insert the device, establish flow reversal, and remove the device

    3. Number of Participants With Technical Success [2 hours (periprocedural)]

      Technical success is defined as acute device success plus the ability to deliver interventional tools

    4. Number of Participants in Which a Cranial Nerve Injury Occurred [90 days (extended follow-up)]

      Rate of cranial nerve injury suspected to be caused by surgical procedure and adjudicated by CEC.

    Adverse Events

    Time Frame Adverse events were collected throughout the life of the study: 3 years, 6 months
    Adverse Event Reporting Description Major adverse events, cranial nerve injuries, device related, and unanticipated adverse device effect event data were collected through 30 day follow-up period and recorded on the Adverse Event CRF. The Investigator or Coordinator determined whether an adverse event occurred Major Adverse Events were defined in this study as stroke, death, or myocardial infarction as adjudicated by Clinical Events Committee. Other Adverse Events (non-serious) were not collected or assessed for this study
