Primary Outcomes (2)

  • Safety Evaluation

    The primary safety assessment is the incidence of serious procedure- and/or device-related adverse events in all subjects at 30 days and at the end of the study. All adverse clinical events will be collected, coded, and reported, for the duration of the study according to the definitions of ISO 14155:2020.
