In carotid angioplasty, a long, hollow tube (catheter) is threaded through the arteries to the narrowed carotid artery in the neck. A filter is inserted to catch any debris that may break off during the procedure. Then, a tiny balloon at the end of the catheter is inflated to open the narrowed area.
