A software issue was identified in the internal communication process between the system software and the X-ray generator firmware. Loss of imaging (X-ray) functionality caused by the software issue in either of the two situations identified could result in a delay of therapy. The potential delay may result in serious adverse health outcomes, including the possibility of death, especially when the system is used with patients undergoing complex and/or urgent interventions for potentially life-threatening conditions (e.g., acute ischemic stroke, ST-segment elevation myocardial ischemia, life-threatening bleedings).
