Manufacturer's investigation conclusion: evaluation of the returned oxygenator confirmed the reported crack in the purge line connector which would have caused the reported leak; however, a specific root cause for this finding could not be conclusively determined.It was reported that the patient was being cannulated for support as a centrimag pre-connected pack was primed.It was reported that the pre-connected pack was found to be leaking significantly through the pigtail on the oxygenator.It was reported that a crack on the connector was discovered, so a new circuit was primed due to concerns for sterility.It was reported that the circuit was not used on a patient, and there was no delay in patient care.Review of the submitted image confirmed an irregular line on the purge line connector that was consistent with a crack.The oxygenator from the centrimag pre-connected pack, pack serial number: (b)(6)/oxygenator lot number: 7558704, was returned, and a visual inspection was performed.The purge line was connected to its port, and short sections of tubing were connected to the blood inlet and outlet ports with ties.Luer caps were noted on the inlet and outlet luer ports.Further inspection of the purge line confirmed two cracks in its connector.Visual inspection of the oxygenator revealed no other obvious damage to the fibers, ports, or external housing.The oxygenator was placed on a mock water loop with test equipment, and the purge line was closed to prevent leaking from the identified purge line connector cracks.The oxygenator operated for 10 minutes on the mock loop, and no other leaks were identified.The relevant sections of the device history records for the centrimag pre-connected pack were reviewed and showed no deviations from manufacturing or quality assurance specifications.Oxygenators in the pre-connected pack undergo 100% visual inspection of the purge line connector, and oxygenators with cracks in the purge line connector are rejected.The centrimag pre-connected pack instructions for use (ifu) warns to not use excessive or damaging force when handling the pack.The ifu warns that a backup pack must be available immediately near the primary pack during support, and if a pack component is dropped and damaged, replace the pack.The ifu warns to monitor the circuit for leaks or other product anomalies.Replace the pack if it does not operate as expected.This section also provides instructions for using the purge line to remove air from the circuit.Once all air has been removed from the circuit, close and clamp the purge line.The relevant sections of the device history record (dhr) for the centrimag pre-connected pack, pack serial number: (b)(6)/oxygenator lot number: 7558704, (documents: (b)(4) were reviewed and showed no deviations from manufacturing or quality assurance specifications.The centrimag pre-connected pack instructions for use (ifu), is currently available.The ifu contains the following general warnings: only trained personnel should use the pack.A backup pack must be available immediately near the primary pack during support.Do not use excessive or damaging force when handling the pack.Pack replacement should be prescribed by the physician based on risks and benefits to the patient.If a pack component is dropped and damaged, replace the pack.Under the section titled ¿prime the centrimag pre-connected pack,¿ the ifu warns to monitor the circuit for leaks or other product anomalies.Replace the pack if it does not operate as expected.This section also provides instructions for using the purge line to remove air from the circuit.Once all air has been removed from the circuit, close and clamp the purge line.The current revisions of the ifu can also be found on the electronic ifu (eifu) page of the abbott website.No further information was provided.The manufacturer is closing the file on this event.
