Carotid Filters Prevent Stroke During Stenting
 
A small filter placed in the carotid artery can help prevent strokes by collecting debris released during stent placements.

The SpideRX embolic protection device, manufactured by ev3 (Plymouth, MN, USA), is a small filter used in carotid artery stenting applications. The device is placed beyond a blockage in the carotid arteries to prevent a stroke or other neurologic event. The device features the ability to choose a preferred guidewire to cross the lesion, a pre-loaded nitinol filter that provides full-body wall apposition, and a dual-ended catheter for delivery and recovery. The filter comes in a variety of sizes, between 3-7 mm, to suit different diameters of the artery at the site of filter-basket placement. The device has been approved by the U.S. Food and Drug Administration (FDA).
