The device was not returned for analysis.A review of the lot history record and similar incident review of the reported lot could not be conducted because the part and lot number were not provided.The reported patient effect of occlusion is listed in the supera peripherial stent system instructions for use as a potential adverse effect of peripheral percutaneous intervention.A conclusive cause for the reported patient effect, and the relationship to the product, if any, cannot be determined.However, the treatment appears to be related to the operational context of the procedure.It is possible that the stent is oversized for the artery and/or pre-dilatation was not enough in some locations causing the stent to stretch/elongate during deployment; however, this could not be confirmed.The investigation determined a conclusive cause for the reported stretched-stent cannot be determined.There is no indication of a product quality issue with respect to manufacture, design or labeling.
