The product was investigated in the laboratory of the mfr.During visual inspection of the blood inlet connector's gluing connection hair-line cracks in the plastic were found.A tightness test was performed and a leakage of this connection was confirmed.By slightly moving the blood inlet connector after it's safety fixture was unfixed from the housing (loosening the screws) it was completely detached from the module.This additional complaint was opened in order to cover this failure.A device history record review was performed by a designated maquet member with no abnormalities found.The review of the quality control process indicated that the oxygenator was tested for its tightness during production.This should be adequate to detect products that do not meet the performance specs prior to release for final packaging and sterilization.Furthermore history records of the glue used for the connector were reviewed with no abnormalities found.The most probably cause of the failure detected is unk.The detected failure was not reported by the customer.This failure was determined to be the first of its kind and is being handled through a designated maquet trending process.If a trend occurs, it will be escalated to quality assurance management for review and determination if further investigation is necessary.Due to this no further action will be completed at this time.
