Carotid Filters Prevent Stroke During Stenting

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).

FDA clearance was supported by a 160-patient high-risk carotid stent registry designed to evaluate the SpideRX rapid exchange embolic protection device for use with the Guidant (Indianapolis, IN, USA) over-the-wire RX Acculink carotid stent system. The safety and efficacy of the SpideRX have not been demonstrated with other carotid stent systems as yet.

"The SpideRX Device is unique in that it allows physicians to utilize their own wire system of choice, leading to consistent success in placing the embolic protection device during carotid interventions,” said Dr. Gary Ansel, of Riverside Hospital (Columbus, OH, USA), the co-principal investigator for the trial.
