Carotid self-expanding stent manufactured by the Balton Company are made of nitinol alloy. The outline of the stents was obtained by means of laser work. A stent is placed at the end of the rapid exchange 0.014” delivery system. After being released from the delivery system, the stent opens up, taking the form of a cylinder. Thanks to its properties, it restores the desirable shape of the lumen of the vessel. The stent is placed between two markers on the distal end of the delivery system.
