Investigation results: a sample/photo was not received for the purpose of our investigation, the investigators were unable to observe the reported failure mode.The batch record was reviewed, no related abnormalities were found.Although the root cause could not be determined without evidentiary support, previous investigations into this issue have shown that the v-clip becomes inactivated as a result of an external force being applied to the safety mechanism during the withdrawal of the cannula.This leads to the offset of the v-clip and unable to activate under normal condition.
