Carotid stents
In the past, vascular surgery was the standard of care for patients with carotid artery disease. Co-existing health conditions preventing patients to have surgical treatment led to the first carotid angioplasty and carotid stenting in 1994.
A carotid stent is a small wire mesh tube, inserted after angioplasty that acts as a scaffold to provide support inside the artery. Although carotid stenting remains investigational, several types of carotid stents are available to use during this procedure.

There are a variety of stents used for carotid stenting - below are three examples of carotid stents:
Caution: These devices are investigational in the United States and are limited by U.S. law to investigational use.
Endotex Carotid Stent
SMART Nitinol Stent
Guidant ACCULINK Carotid Stent System
Carotid stenting filter devices
Emboli protection devices have improved the safety of carotid stenting. Strokes that occur during, or in the first few minutes after, carotid angioplasty and stenting are caused by microemboli (tiny particles in the blood) dislodging and traveling to small distal blood vessels in the brain. Filter devices, combined with antiplatelet medication, provide protection against microemboli. The filter device's microscopic-sized holes allow blood flow to continue as particles are captured in the device. At the end of the procedure, the filter is removed from the carotid artery along with captured debris. The rate of complications, including stroke, myocardial infarction (MI), and death, at the Cleveland Clinic Foundation are about 3 percent.
