The event unit was returned to applied medical for evaluation.Visual inspection confirmed the complainant's experience of damaged cannula and obturator.Based on the condition of the returned unit, it is likely that the reported event was caused by process variations during the manufacturing process in combination with the force applied during insertion.The probability and criticality of harm resulting from this failure have been evaluated and were found to be at an acceptable level.Applied medical will continue to monitor its vigilance system for trends and take appropriate actions, as necessary, to ensure the performance and safety of its products.This report represents the combined initial and final.
