The system was used for treatment.This case is reportable as a mdr due to the reportable malfunction centrifuge bowl 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 g120 was conducted.There were no non-conformances associated with this lot.This lot met all release requirements.A review of kit lot g120 for the reported issue shows no trends.Trends were reviewed for complaint category, centrifuge bowl leak/break.No trends were detected for this complaint category.The complaint kit, smartcard and photographs were returned for investigation.A review of the data recorded on the smartcard verified the treatment was completed and no blood leak alarms were recorded on the card.The photographs provided by the customer show a line of red spatter running across the inside of the centrifuge on the wall and on the inside of the centrifuge door.The returned kit was examined and found no evidence that a blood leak had occurred.The centrifuge bowl and drive tube component of the kit were pressurized and held under water, no bubbles emerged from either component.The centrifuge bowl and drive tube were installed onto a test instrument for dynamic testing.The centrifuge was spun at 2400 rpm for 12 minutes; the centrifuge leak sensor did not indicate any leaks.The centrifuge was checked after testing and found no residue or leaks on the centrifuge walls.Pressure testing and dynamic testing of the bowl and drive tube did not find any leaks.The root cause of the reported centrifuge bowl leak/break could not be determined as no cellex kit defect could be identified upon evaluation of the returned product.No further action is required at this time.This investigation is now complete.(b)(4).
