Visual and dimensional analysis was performed on the returned device.The reported difficulty removing the catheter was unable to be confirmed due to the device condition; however, damage to the dragonfly catheter which is consistent with the reported event was observed.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.A query of the complaint handling database for the reported lot was performed and revealed there is no indication of a lot level quality product issue.The investigation determined that the difficulties were likely related to circumstances of the procedure.The torn guide wire exit port noted on the returned dragonfly catheter suggests that the guidewire and catheter were likely spread apart during removal causing the guidewire to tear into the exit port of the dragonfly resulting in difficulty removing and damage to the guide wire tip coils.While the reported withdrawal issue could not be confirmed, it is likely that either the patient¿s anatomical condition(s) or the guide catheter size affected the withdrawal; however, this could not be confirmed.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
