Investigation: the complaint sample was not returned, thus a product investigation was not possible.Review of device history records: the device quality and manufacturing history records (dhr) have been checked for all available lot numbers and the products found to be according to our specification valid at the time of production.The batch-related complaint history review did not reveal any similar complaints for the reported failure mode.Explanation and rationale: due to a lack of information and without the product we cannot determine a root cause for the mentioned deviation.According to the quality standard and the dhr, a production error and a material defect can most probably be excluded.A malfunctioning clip loading / clip charging process can have a variety of reasons, including possible failures in each individual component of the challenger system such as the used handle, the shaft and/or the clip cassette.If further investigations are required, the product should be provided for examination.Conclusion and preventive measures: root cause cannot be finally concluded.Therefore the root cause specific risk cannot be identified.The potential risk determined during initial vigilance evaluation remains valid.Based upon the investigation results, a capa is not necessary.
