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.

Creighton University research to improve patient care and outcomes in CAD treatment

Since 1990, Creighton University School of Medicine professor and researcher Devendra K. Agrawal, Ph.D., has been awarded more than $20 million in research grants to study coronary artery heart disease. He is determined to eradicate the impact of this heart disease—the number one killer of men and women in the United States.

Trevo Retriever effectively removes blood clots in patients with stroke

Every 40 seconds, someone in the United States has a stroke, usually caused when a clot blocks an artery that supplies blood to the brain. Now the results of two multicenter studies published online in The Lancet on August 26 are giving physicians new innovative tools proven to better remove these clots that block blood flow.

Endovascular brachytherapy may safely and effectively treat femoropopliteal in-stent stenosis

Placement of an endovascular stent has become a common procedure to successfully reopen blocked arteries. Even so, the treated vessel may once again narrow (restenosis), restricting blood flow. In the femoral and popliteal arteries in the leg, the use of nitinol stents magnifies this problem. About 20 to 40 percent of these stent patients experience restenosis 2 years after angioplasty. Now, an improved radiation technique may provide a safe and effective solution.

Study demonstrates MRI role in defining and understanding causes of MS

New magnetic resonance imaging (MRI) research shows that changes in brain blood flow associated with vein abnormalities are not specific for multiple sclerosis (MS) and do not contribute to its severity, despite what some researchers have speculated. Results of the research are published online in the journal Radiology.

FDA approves label changes for Stryker Wingspan Stent System

The U.S. Food and Drug Administration today approved changes to the labeling for the Stryker Wingspan Stent System, including the indications for use. These changes, which the FDA outlined in a safety communication also issued today, specify a more limited group of patients who may benefit from the system.

Cardionovum to introduce PROLIMUS Biograde system in Europe

Cardionovum GmbH announced today that it expects to launch in Europe in Q4 2012 a next-generation Sirolimus-eluting coronary stent system—PROLIMUS Biograde—which is designed to optimize long-term patient results. Unlike many state-of-the-art DES that are currently being marketed, PROLIMUS Biograde provides multiple pro-healing product features to promote early re-endothelialization.

Link between cardiac catheterizations and risk of stroke

When a patient undergoes a cardiac catheterization procedure such as a balloon angioplasty, there's a slight risk of a stroke or other neurological complication.

Pre-hospital electrocardiography offers more timely diagnosis of heart attack

A study conducted by researchers from the University of California, San Diego School of Medicine along with colleagues from Rural/Metro Ambulance San Diego and the San Diego Fire-Rescue Department, shows that emergency medical personnel can obtain an electrocardiogram (ECG) in the field for chest pain patients without an increase in scene time or transport time to the hospital.

Blood flow in blocked arteries to extremities improved by new angioplasty procedure

Patients with blocked arteries to their extremities, known as peripheral artery disease (PAD) or critical limb ischemia (CLI), may now find relief from lower leg pain and wounds caused by impaired leg artery circulation with the previously unproven therapy, percutaneous transluminal angioplasty (PTA).

Study confirms safety and feasibility of optical coherence tomography in carotid arteries

Our ability to see inside the arteries of vascular disease patients in stunning high resolution before and during stenting procedures can offer a wealth of valuable information. A new study of optical coherence tomography (OCT) confirms the safety and feasibility of this imaging technique in the carotid arteries.

Researchers begin to uncover important clues about SCAD

Spontaneous coronary artery dissection (SCAD), a tear of the layers of the artery wall that can block normal blood flow into and around the heart, is a relatively rare and poorly understood condition. It often strikes young, otherwise healthy people -- mostly women -- and can lead to significant heart damage, even sudden death.
