Manufacturer Narrative

The product was not available for investigation, therefore no laboratory investigation could be performed by the manufacturer.A review for similar complaints that were investigated had the following outcome: the product was visual inspected in the laboratory of the manufacturer.No clots were detected during rinsing of the product for cleaning purposes.The product was tested for its o2-transfer rate and co2 transfer rate as well as for its pressure drop at maximum flow.The gas exchange performance test and the pressure drop test meets the specification.Thus the reported failure could not be confirmed.The cause of this failure was determined to not be attributed to a device related malfunction.Based on these results and the information available at this time, the oxygenator in question operated within mcp specifications.Since the reported failure did not contribute to a death or serious injury and no systemic issue could be determined no corrective action is needed at this time.The data is also being handled through a designated maquet cardiopulmonary trending and applicable investigation process.Due to this no further investigation initiations will be completed at this time.
