During an angioplasty, the catheter is inserted into a blood vessel to gain access into the circulation. Under the radiographic fluoroscopic visual guidance, the catheter is threaded along the course of the vessels to reach the target vessel, which may be a carotid artery, a renal artery, a peripheral artery in the leg, or most commonly, a coronary artery. At that time, the balloon is expanded to dilate the vessel, and the stent is opened, released, and adhered to the artery wall. The stent, which remains in the artery...
