B3: date of event has been estimated the device was not returned for evaluation.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 effects of dissection and perforation are listed in the supera peripheral stent system instructions for use (ifu) as a potential adverse event.The investigation determined a conclusive cause for the reported stretched-stent and the reported defective device-shortened cannot be determined.A conclusive cause for the reported dissection and perforation, and the relationship to the product, if any, cannot be determined.The treatment appears to be related to the operational context of the procedure.There is no indication of a product quality issue with respect to manufacture, design or labeling.The deaths reported in the article are being captured under a separate medwatch report number.Literature attachment: article title: drug coated balloon improves outcomes of sub-optimal supera deployment in the intermediate termna.

It was reported in a research article that sub optimal deployment of a supera stent has been shown to increase the rate of clinically driven target lesion revascularization (tlr).Supera stents were implanted in the femoral-popliteal arteries in de-novo and restenotic lesions.The purpose of this study was to assess the outcomes of clinically driven re-intervention, amputations and mortality in relation to use of a drug coated balloon as vessel preparation in different deployment conditions of supera stents (including nominal, elongated and compressed).There was death, amputation, dissection, perforation, target lesion revascularization, and elongated and condensed stent deployment requiring intervention.Vessel preparation with a drug coated balloon may reduce tlr regardless of supera deployment status.Additional details can be found in the attached article "drug coated balloon improves outcomes of sub-optimal supera deployment in the intermediate term".
