This is the product code that is not required to be registered with fda.The actual device has been returned to the manufacturing facility for evaluation.Visual inspection of the actual device upon receipt found that the gas in side and the gas out side had been discolored into pink with a fluid pink in color gathered in the gas in side.The fluid gathered in the gas in side was collected and centrifugalized.As the result, no deposition occurred in it.This indicated that this fluid did not contain the blood cell components.The actual device was rinsed and filled with saline solution.With the blood outlet port clamped, an air of 2.0kg/cm2 was applied to the inside of the device from the blood inlet port.No leak was confirmed.The actual device, after having been dried, was tested for its gas transfer performance.Bovine blood was circulated in the oxygenator module under the following conditions: @ v/q=1, fio2=100% and the flaw rate of 6l/min.And 4l/min.Result: o2 transfer: @6l/min.= 403ml/min.@4l/min.= 283ml/min.Co2 removal: @6l/min.= 342ml/min.@4l/min.= 237ml/min.No anomalies were revealed in the gas transfer performance of the actual sample, with the obtained values meeting manufacturer specifications.A review of the device history record and product release decision control sheet of the involved product code/lot number combination revealed no relevant findings.A search of the complaint file found no previous report of this nature with the involved product code/lot number combination.There is no evidence this event was related to a device defect or malfunction.The above investigation verified that the actual device was the normal product without any defectives which could have led to a leak or the insufficient gas transfer performance.While the exact cause of the reported event cannot be definitively determined based on the available information, based on the findings that the fluid gathered inside the gas in side did not contain the blood cell components and that the actual device did not have any leak, it is likely that a plasma leak occurred during the actual use.The device labeling does address the potential for such an event in the instructions-for-use (ifu) with statements such as the following: do not use this product for the period in excess of six hours.Excessive use for over six hours may lead to plasma leak and thrombi formation, which may compromise the gas exchange performance.(b)(4).
