Manufacturer Narrative

This report is being submitted as follow up no.1 to provide the device return date in section d9, to update sections d4 and h4, to update section h3, and to provide the completed investigation results.The actual sample was received for evaluation.Visual inspection revealed no obvious anomalies, such as a break, in the appearance.The actual sample after rinsed and dried was built into a circuit with tube, and then bovine blood (hct 35% and temp.37°c) was circulated in the circuit at 5 l/min, while the pressure drop was determined.The obtained values were confirmed to meet the manufacturer specifications.No obstruction was confirmed.A review of the device history record and the product-release judgement record of the involved product code / lot# combination was conducted with no findings.Ifu states: do not reduce heparin during circulation.Otherwise, blood clotting might occur.Adequate heparinization of the blood is required to prevent it from clotting in the system.Based on the provided information and investigation results, there is no definitive evidence that this event was related to a device defect or malfunction.The investigation results verified the returned sample was of normal product.It is likely that clogging derived from blood occurred due to some factors, resulting in the pressure rise.However, the exact cause of the reported event cannot be definitively determined based on the available information.
