The event unit was returned to applied medical for evaluation, along with a clear fragment.Visual inspection confirmed the complainant's experience of seal component separation.The shield, a clear plastic internal component of the seal, had been dislodged and was missing a piece.The clear fragment matched the missing portion of the shield.The septum, a rubber component of the seal, was observed to be fragmented as well.Based on the condition of the returned unit and the description of the event, it is likely that the reported event was caused by non-axial insertion or removal of asymmetrical instruments through the trocar.Applied medical's instructions for use states that, "extra care should be used when inserting angular and asymmetrical instruments, such as 'j' hooks and clip appliers.All instruments should be centered axially when inserted through the seal to prevent tearing." 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.
