The device was not returned for evaluation.A review of the lot history record of the reported lot could not be conducted because the part and lot number was not provided.Reportedly, it was noted the vessel diameter is 9mm and the supera stent is 6mm.A conclusive cause for the reported patient effects, and the relationship to the product, if any, cannot be determined.However, the treatments appears to be related to the operational context of the procedure as thrombolytic therapy and angioplasty was preformed.It should be noted that the supera peripheral stent system instructions for use states: the stent sizes are labeled based on the outer stent diameter.A stent should initially be chosen such that its labeled diameter matches the reference vessel diameter (rvd) proximal and distal to the lesion.Final stent selection should be confirmed after lesion pre-dilation: if possible, the stent diameter should match the prepared lesion diameter 1:1.Choosing a labeled diameter to match the reference vessel diameter, then appropriately preparing the vessel to match that stent¿s diameter will result in a stent that is properly sized to the vessel.The deviation of the instructions for use likely contributed to the reported difficulties.There is no indication of a product quality issue with respect to manufacture, design or labeling.Dates estimated literature attachment: article title: "using undersized supera in the superficial femoral artery as a coil.".
