Manufacturer Narrative

Additional evaluation method code used: sterilization process review investigation: a review of the device history record (dhr) for this unit showed no irregularities during manufacturing that were relevant to this issue.Two sets were received for investigation.Set # 1 was a dry set.Visual inspection showed the set was assembled correctly.The set was loaded and passed pressure testing with no issues.No abnormal sounds were noted during testing.Set # 2 was received containing ac and saline.Visual inspection showed the set was assembled correctly.The set was loaded and passed pressure testing and ac/saline prime with no problems and no abnormal noises were noted.Root cause: using the available evidence, a misload is most likely the cause the abnormal noises in the centrifuge.If the loop¿s bearings are not placed completely into the holders of the centrifuge arm, centrifugal force can cause the braided loop portion of the tubing to hit against the inner basin wall while the centrifuge is spinning.This would cause the reported abnormal noises.The lack of evident damage on the sets can be explained because the procedures were halted during prime.Additional information: the customer's site was contacted to determine if the facility wanted re-training regarding the misload, the customer declined the re-training.
