Manufacturer Narrative

A visual evaluation of the returned rx cytology brush revealed that the pull wire was broken at the distal end of the handle cannula, and it was also noticed that a kink was found in the same location.The extrusion is free of obvious kinks and bends.Further evaluation noted that the distal section (catheter and the bristled portion) of the device was cut by the customer with a sharp tool.A functional analysis was not performed due to the condition of the returned device.It is most likely that the pull wire being kinked at the distal end of the handle cannula could have caused difficulty to extend/retract the brush.Due to excessive manipulation of the device, it would cause the pull wire to break.Based on all gathered information, the most probable cause of this complaint is ¿manufacturing process design¿, since it is most likely that design or validation of the manufacturing process was not sufficient to ensure the finished device met the intent of the design.There is an investigation in place to address this issue.A review of the device history record (dhr) was performed and no deviations were found.
