Manufacturer Narrative

Analysis of the returned rx cytology brush revealed multiple bends in the working length and the pull wire had become broken at the end of the hypotube.Brush was extended in position, and the blue cap and t-fitting threads were undamaged.The catheter had been cut by the user from the heat shrink.The event was most likely caused by some operational or anatomical aspect of the procedure which restricted the pull wire¿s ability to move freely within the catheter.Attempts to extend and retract the brush with pull wire movement restricted resulted in the broken pull wire.Therefore, the most probably root cause for this event is determined to be operational context.
