Maquet cardiopulmonary (b)(4) requested the product for investigation and it was returned and the investigation documented in an investigation report dated (b)(4) 2015.The cannula was disinfected and cleaned with sodium hypochlorite.The product was visually inspected and it was found that the cannula was damaged (the photographic evidence clearly shows a kink in the cannula).A leakage test was performed and no leaks were found; the damaged area was watertight.There is insufficient information available to evaluate this case fully, and it has not been possible to establish how the cannula was fixed, and the details about how it was used.Only photographs of the returned product were available, and in order to reach a probable root cause, the assistance of the research and development engineer, product manager, quality engineer in turkey, and the therapy application / clinical risk manager was sought.The conclusion from the clinical assessment was that the most probable root cause is a user issue (that the product was used outside normal and expected use).Additionally, the device history record of the affected lot was investigated and no anomalies were found, and there was no scrap record found for the related material.As there is no further information available regarding this case, the exact failure mode is not known, and a search in sap found no related issues for the material number in question, no further investigation or action is warranted or possible.This is the final report.
