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 investigation determined the reported activation/deployment failure appears to be related to circumstances of the procedure as it is likely that the during stent deployment the introducer sheath was too close to the proximal end of the stent; thus resulting in the stent to partially deploy into the introducer sheath.As reported, when the sheath was pulled the stent moved into the common femoral/external iliac artery and remains there; thus resulting in the reported migration.There is no indication of a product quality issue with respect to manufacture, design or labeling.
