The system was used for treatment.This case is reportable as a mdr due to the reportable malfunction pto leak.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 j369 was conducted.There were no non-conformances associated with this lot.This lot met all release requirements.A review of kit lot j369 shows no trends.Trends were reviewed for complaint categories, pto leak and alarm #18: system pressure.No trends were detected for these complaint categories.A photograph was provided by the customer for evaluation.The complaint kit was not returned.Review of the customer provided photograph verifies the pump tubing organizer (pto) leak as blood is seen leaking from the y-connector inside the pto.The leak appears to be coming from the bond where the y-connector joins the plasma line to the treatment bag and return bag inlet lines.A material trace of the components used to build kit lot j369 found one related non-conformance.The related non-conformance was associated with y-connector lot # 1000835 which involved a leak identified at the same location during lot release testing.A review of all pto leaks documented in mallinckrodt's electronic complaint database from january 2020 to present did not identify any similar occurrences associated with y-connector lot # 1000835.There were no other pto leaks observed for kit lot j369.A device history record review for kit lot j369 did not identify any related non-conformances and this kit lot had passed all lot release testing.The reported alarm #18: system pressure alarm was most likely caused by the leak at the y-connector.The root cause of the leak was most likely due to a weak solvent bond or due to a sink in the y-connector bond socket; however, a definitive root cause could not be determined based on the available information.No further action is required at this time.This investigation is now complete.(b)(4).P.T.(b)(6) 2021.
