The system was used for treatment.This case is reportable as a mdr due to the reportable malfunction drive tube leak/break.Since this reportable malfunction is only associated with the kit, this mdr will only be against the kit.A batch record review for kit lot l319 was conducted.There were no non-conformances associated with this lot.This lot met all release requirements.A review of kit lot l319 shows no trends.Trends were reviewed for complaint categories, alarm #7: blood leak? (centrifuge chamber) and drive tube leak/break.No trends were detected for these complaint categories.Photographs were provided by the customer for evaluation.The complaint kit and smart card were not returned.The provided photographs verify the reported drive tube leak as blood splatter is seen on the centrifuge chamber walls.The upper drive tube bearing is not installed into the drive tube retainer clip.The upper drive tube bearing is seen halfway down the length of the drive tube.If the drive tube bearing is not securely loaded into its retainer clip, the centripetal force would cause the bearing to move to the center of the drive tube and eventually impact the centrifuge chamber wall, resulting in a leak.A material trace of the drive tube assembly and its components used to build lot l319 found no related non-conformances.The requested device history record (dhr) review did not identify any related non-conformances, deviations, or equipment maintenance events.This lot passed all lot release testing.The root cause for the alarm #7: blood leak? (centrifuge chamber) is most likely due to the drive tube leak.The root cause for the drive tube leak is most likely due to the drive tube bearing not being secured into its retainer during installation of the kit by the end user.No manufacturing related defects were identified during this investigation.No further action is required at this time.This investigation is now complete.(b)(4).
