In carotid stenting, a long, hollow tube (catheter) is threaded through the arteries to the narrowed carotid artery in the neck. A metal mesh tube (stent) is inserted into the vessel to serve as a scaffold that helps prevent the artery from narrowing again. The catheter and the filter — which catches any debris that may break off during the procedure — are removed.
