Implanted date: device was not implanted.Explanted date: device was not explanted.Initial reporter occupation- clinical engineer.Pma/510(k)- k130280.The actual sample was received for evaluation.Visual inspection of the luer thermistor revealed no break, deformity, or other obvious anomaly that could lead to the leak.Blood was found adhering to the end of the tube connected to the bcp port.The actual sample was connected to a circuit with tube, filled with normal saline (colored for better visibility), and then circulated at 3000 rpm with a centrifugal pump.As a result, no leak occurred.Then, the tube attached to the bcp port was squeezed with fingers.As a result, leak occurred.The bcp port after separated from the tube was inspected under a magnifier.No deformity or no other obvious anomaly was observed.Compared to a current product sample, no difference in the outer diameter was observed.The actual sample after rinsed was connected to a factory-retained tube, the blood channel was filled with normal saline, and the blood outlet port side was blocked with forceps.Then, the actual sample was pressurized at 2kgf/cm2 from the blood inlet port side for six hours.As a result, no leak was observed.A review of the device history record and product release decision control sheet of the involved product code/lot# combination was conducted with no findings.Ifu states: band all connections in the circuit.Do not use an oxygenator and reservoir that leaks.Replace it with another capiox fx25 oxygenator and reservoir.Based on the provided information and investigation results, there is no definitive evidence that this event was related to a device defect or malfunction.It is likely that the blood leaked at the bcp port connection area and reached the luer thermistor section.However, the exact cause of the reported event cannot be definitively determined based on the available information.(b)(4).
