The event unit was returned to applied medical for evaluation.Visual inspection confirmed the complainant's experience of seal component separation.The shield, a clear plastic internal component of the sleeve, was dislodged and was damaged.The septum, a rubber component of the seal, was also fragmented.Based on the condition of the returned unit, it is likely that the reported event was caused by non-axial insertion of an instrument or an asymmetrical instrument that was used during the procedure.The instructions for use (ifu) states that "extra care should be used when inserting angular and asymmetrical instruments, such as 'j' hooks and clip appliers," and "all instruments should be centered axially when inserted through the seal for easier insertion." 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.
