The device was not returned for investigation.Our investigation process included the following reviews: complaint history, ifu, qc and trends.The description of event stated, "a week after the placement, deviation of it from the placed position was confirmed.When this event was confirmed, the mac-lock of the catheter was firmly locked.If mac-lock functioned as intended, the catheter would not deviate.Considering above, i (user) am not sure, but i think there is a possibility that the suture of it was separated somehow and this event occurred." based on the description, it is likely that the suture broke while in the pt causing the tip of the catheter to uncurl and move from its original position.Per qc specification, ac personnel confirms the integrity of the device.The device is shipped with ifu, which lists the appropriate warnings, precautions and instructions for use.Due to the limited info and without the device for investigation, a definitive root cause cannot be determined.We have notified appropriate personnel and will continue to monitor for similar complaints.Insufficient risk per quality engineering risk assessment.
