This report is being submitted as follow up no.1 to provide a correction to section b5 as it was inadvertantly reported that the procedure outcome was unknown when it should have been reported that the procedure outcome was successful.This report is also being submitted to provide the device return date in section d9, update section h3, and to provide the completed investigation results.Visual inspection of the actual sample upon receipt did not find any anomaly such as a breakage in its appearance.After rinsing the actual sample, it was installed into a circuit consisting of tubes, and colored saline solution was circulated.As a result, leakage from the gas outside was found.The actual sample was filled with dyeing solution to dye the leakage path, the housing and heat exchanger were removed, and visual and magnifying inspections were performed.As a result, it was found that the leakage path was generated along the fiber in the urethane potting part.In addition, foam was observed around the leakage path.X-ray fluoroscopic inspection of the actual sample near the leaked section found a part where urethane was not filled due to the foam.Review of the manufacturing record and the product release decision control sheet of the actual sample confirmed that there were not any indications of anomaly in them.A search of the complaint file for the past three years found no other similar report.Based on the investigation result, as a cause of leakage from the gas outside, it was likely that there was a leakage path in the urethane potting part.In ashitaka factory manufacturing process, 100% leak test is performed.Therefore, it was likely that during the period from when the product flowed in the production process as a non-defective product in this leak test to when it was used, some excessive force was applied, causing peeling at the foamed section and generating the leakage path.However, it was not possible to clarify when this event occurred.Ifu states: "do not use an oxygenator and reservoir that leaks.Replace it with another capiox fx15 oxygenator and reservoir.If the product is dropped during set-up, do not use it.Replace with another device." terumo medical products (tmp) (importer) registration no.2243441 is submitting this report on behalf of ashitaka factory of terumo corporation (manufacturer) registration no.9681834.
