Study Said to Back Guidant Artery Device

CHICAGO, March 30 -- Researchers presented new evidence today that a minimally invasive technique might be the best way to treat high-risk patients with clogged arteries in the neck who are at risk of a stroke. The study, released at a meeting of cardiologists in Chicago, showed patients who were poor candidates for surgery fared well when tiny, wire-mesh tubes called stents were implanted to prop open clogged carotid arteries.

A trial of 513 patients treated with a stent found the procedure to be safe and effective at treating those who are at high risk in about 92 percent of cases.

Guidant, a medical device maker, sponsored the study, which used the company's Acculink carotid stent system. The device includes a trap that collects fatty deposits loosened during stent placement before they can make their way to the brain.

In November, Johnson & Johnson released results from a similar trial showing the treatment was effective.

Some rivals, Boston Scientific, Medtronic and C. R. Bard, have clinical trials under way using stents to treat carotid arteries.
