A non-bioabsorbable tubular device intended to be implanted in a peripheral artery (excludes aorta, coronary, pulmonary, and intracranial arteries) to indefinitely maintain patency and improve luminal diameter in patients with atherosclerotic disease, or following the recanalization of a total occlusion. It may additionally be intended to be implanted in an obstructed biliary duct; it is not dedicated to carotid artery implantation, and not intended for connection with an aortic stent. It is made entirely of metal [e.g., Nitinol alloy mesh structure] and typically implanted by a dedicated instrument where it self-expands upon release or is balloon expanded.
