Investigation: no product at hand, therefore an investigation is not possible.Batch history review: we did not receive any information regarding the batch of the complained product, therefore a review of the device history records remain incomplete.Conclusion and root cause: the failure is most probably usage related.Rationale: on the basis of the provided information and the statistical analysis, we exclude a product related failure.Due to the fact that we did not receive the product, a clear conclusion can not be drawn.Within the last three years, we received six similar complaints.Five of these six complaints were reported by the same hospital, therefore we assume a usage related failure.Internally, the failure pattern could be simulated with a sample instrument.If too much force is applied several times to the instrument during the clip application, a damaging of the weldseam of the above mentioned pin is possible.The surgeon has to press the ds clip application forceps together to the stop, as mentioned in our ifu.There is no excessive force indicated during use.No capa is necessary.
