Manufacturer Narrative

(b)(4).A celebrity cytology brush was received for analysis.Visual inspection of the returned device revealed that the working length (sheath) was detached from the handle.Additionally, working length (pull wire at proximal section and sheath at distal end) was also kinked.Even though functional inspection was not performed, findings from the visual evaluation indicated that there were issues with extending/retracting the brush properly.No other issues were noted.Based on all available information, boston scientific concludes it is most likely that the handling and manipulation of the device during unpacking/prepping/testing can lead to kinks in the working length (sheath and pull wire), once the device is kinked it can cause issues to extend/retract the brush due to the friction between the components at the kinked areas, continued attempts to extend/retract the brush or force applied to the device in order to extend/retract the brush can result in working length detachment from the handle.Based on the information available and the analysis performed, the most probable root cause classification is adverse event related to procedure.A review of the device history record (dhr) was performed and confirmed that this device met all material, assembly and performance specifications.
