(b)(4).One eus fna needle was received by boston scientific.Analysis of the returned device revealed that the working length (sheath and needle) wa kinked at distal end of the handle with the sheath length adjust set at 1, also distal section of the working length was bent.During functional inspection the handle was actuated and the needle extended, once the needle was extended, it was observed that the needle tip was detached from the device.The detached distal needle tip was not received for analysis.No other issues were noted.It is most likely that anatomical or procedural factors encountered during the procedure could have caused the damages found on the device.Handling/manipulation of the device during its use can lead to kink/bent the working length (sheath and needle) near the handle and distal section, severe bending of the needle at distal section can result in needle breakage.All compiled information on this investigation determines that the most probable cause is adverse event related to procedure, since the adverse event occurred during the procedure and the device had no influence on event.A review of the device history record (dhr) was performed and confirmed that this device met all material, assembly and performance specifications at the time of release for distribution.
