Stent News and Research

RSS

A stent is a small mesh tube that’s used to treat narrowed or weakened arteries in the body.

You may have a stent placed in an artery as part of a procedure called angioplasty (AN-jee-oh-plas-tee). Angioplasty can restore blood flow through narrowed or blocked arteries. Stents help prevent arteries from becoming narrowed or blocked again in the months or years after treatment with angioplasty. You may also have a stent placed in a weakened artery to improve blood flow and to help prevent the artery from bursting.

Stents are usually made of metal mesh, but sometimes they’re made of fabric. Fabric stents, also called stent grafts, are used in larger arteries. Some stents are coated with medicines that are slowly and continuously released into the artery. These medicines help prevent the artery from becoming blocked again.

Spectranetics seeks FDA clearance for treating in-stent restenosis in the legs

Spectranetics Corporation today announced that it has filed a 510(k) application with the Food and Drug Administration seeking clearance for the treatment of in-stent restenosis (ISR) in the legs with its commercially available peripheral atherectomy products. ISR is caused by the re-growth of tissue within the stent, known as neointimal hyperplasia, which can lead to blockages in the affected leg artery.

HORIZONS-AMI clinical trial demonstrates efficacy of drug-eluting stent

Late-breaking data from the landmark HORIZONS-AMI clinical trial, presented at the 21st annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium, demonstrated that after two years, in heart attack patients, the use of a drug-eluting stent (paclitaxel) was safer and more effective than a bare-metal stent; and that the administration of the anticoagulant medication bivalirudin enhanced safety and efficacy compared to the use of heparin + GPIIb/IIIa inhibitors.

Everolimus-eluting stent efficient in treating native coronary artery lesions

Late-breaking data from SPIRIT IV, a large-scale multi-center study of nearly 4,000 patients in the U.S., shows that an everolimus-eluting stent demonstrated enhanced safety and efficacy in the treatment of de novo native coronary artery lesions when compared to a paclitaxel-eluting stent, and showed that "low late loss" may be achieved with drug-eluting stents without sacrificing safety.

Clinical trial comparing Boston Scientific's coronary stent systems

Boston Scientific Corporation today welcomed one-year data from the SPIRIT IV clinical trial comparing the XIENCE V((R)) (PROMUS((R))) Everolimus-Eluting Coronary Stent System to the TAXUS((R)) Express2(TM) Paclitaxel-Eluting Coronary Stent System. The results support the benefits of paclitaxel-eluting stents in diabetic patients. The trial enrolled 3,690 patients, including 1,140 diabetics, the largest diabetic subset ever studied in a drug-eluting stent clinical trial.
