The device was not returned for analysis.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no other incidents from this lot.The reported patient effect of ischemia is listed in the supera peripheral stent system instructions for use as a potential adverse effect of peripheral percutaneous intervention.A cine was received and reviewed by an abbott vascular clinical specialist: it was reported that at a 3 month follow-up, a break in an supera stent implanted in the popliteal artery was discovered.The image provided clearly shows a fracture in the supera stent at the knee joint.A specific cause of the stent fracture is not able to be determined.Bending at the joint would be a likely contributing factor.It is possible that bending at the knee joint and/or stress/fatigue/repetitive movement due to anatomical conditions resulted in the reported stent break; however, this could not be confirmed.The investigation determined a conclusive cause for the reported difficulties cannot be determined.The reported difficulties possibly caused/contributed to the reported patient effects, however a conclusive cause for the reported patient effects, and the relationship to the product, if any, cannot be determined.The treatments appears to be related to the operational context of the procedure as reportedly revascularization was performed with balloon angioplasty and a new 5.5x150mm supera stent was implanted.There is no indication of a product quality issue with respect to manufacture, design or labeling.
