Visual and dimensional analysis was performed on the returned device.The reported difficulty removing the catheter was able to be confirmed; however, a conclusive cause of the difficulty could not be determined due to device condition.A dimensional analysis was performed.It was determined that the diameter of splice region of the catheter and non-abbott guidewire met the specification; however, a torn guide wire exit port was noted on the returned dragonfly.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history revealed no other similar incidents.The investigation determined that the difficulty was 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 guide wire to tear into the exit port of the dragonfly resulting in difficulty removing.It is likely that either the patient¿s anatomical condition(s) or the guide wire condition affected the withdrawal.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
