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.

Stenting and surgery equally effective at lowering long-term risk of stroke

Investigators for the Carotid Revascularization Endarterectomy versus Stenting Trial found that stenting and surgery are equally effective at lowering the long-term risk of stroke from a narrowed carotid artery, according to a study published today in The New England Journal of Medicine.

Benefit of using antibody-coated drug-eluting stents for CHD still unclear, shows report

In patients with coronary heart disease requiring a stent implantation, the benefit of treatment with antibody-coated drug-eluting stents (ABC-DES) versus drug-eluting stents without antibody coating (DES) is still unclear.

Vascular surgery safer than stenting for older patients with carotid stenosis

Vascular surgery appears to be safer than stenting for patients over 70 years of age with carotid stenosis, or a blockage of the carotid arteries in the neck, according to new findings published today in the Lancet.

Ultrasound-activated microbubbles help preserve healthy heart tissue

Researchers funded by the National Institute of Biomedical Imaging and Bioengineering used ultrasound-activated microbubbles to improve preservation of heart muscle and function in a pig heart attack model.

UPMC uses simple gene test to personalize medications for patients undergoing heart catheterization

Patients who go to UPMC Presbyterian for heart catheterization and who receive a stent to treat clogged arteries are now being screened with a simple blood test to determine if they have a gene variant that makes them less likely to respond to a blood-thinning medication commonly prescribed after the procedure.

New technique may reduce need for amputation in patients with critical limb ischemia

A new imaging technique could reduce the need for amputation in patients with critical limb ischemia, according to a study publised today in the scientific journal JACC.

TCAR procedure offers potentially safer method for high-risk stroke patients

The carotid arteries supply oxygenated blood to the brain. Every year, more than 300,000 people in the United States are diagnosed with blockages, or plaques, in their carotid artery. When these arteries become blocked due to plaque build-up, an individual is at high risk for a stroke if the plaque ruptures and flows to the brain.

New study finds efficacy of novel intravenous blood thinner in women

Percutaneous coronary intervention (PCI) is a staple of modern day medicine in which cardiologists place a stent in a blood vessel around the heart in order to restore blood flow in people with heart disease. Blood thinners allow for the procedure to be completed with a reduced risk of certain complications such as clots.

Scientists develop a method for cell replacement in diseased vessels

In industrialized countries, a particularly high number of people suffer from arteriosclerosis -- with fatal consequences: Deposits in the arteries lead to strokes and heart attacks. A team of researchers under the leadership of the University of Bonn has now developed a method for guiding replacement cells to diseased vascular segments using nanoparticles.

Penn study explores bleeding complications linked to cardiac stent placement techniques

More than 375,000 American each year experience a heart attack, during which blood flow to a part of the heart is impeded by blocked arteries. Physicians often treat patients with stents, which prop open the arteries to allow blood to flow again. They use two approaches to place stents: transradial, or entry of the catheter which delivers the stent through the wrist, or transfemoral, in which the catheter is placed through the groin.

Study examines whether treating multiple narrowed arteries has adverse effect on the heart

A new study has examined the effects on the heart of treating multiple narrowed arteries - rather than just one - at the time of a heart attack.

Treatment with antiplatelet therapy does not reduce pain crises in children with sickle cell disease

Treatment with the antiplatelet agent prasugrel does not significantly reduce the rate of pain crises or severe lung complications in children with sickle cell disease, according to a report published in the New England Journal of Medicine describing one of the largest and most geographically diverse international clinical trials on sickle cell disease to date.

Medinol introduces NIRxcell CoCr Stent System to coronary marketplace

During the recent 2015 Transcatheter Cardiovascular Therapeutics Meeting held in San Francisco, CA, Medinol Ltd. continued to introduce novel stent solutions to the coronary marketplace. During a satellite symposium, "The BioNIR eDES: The Role of Uniformity in Stent Design to Minimize Restenosis", a renowned physician panel discussed the key attributes of the currently available Medinol NIRxcell CoCr Coronary Stent System and the Medinol eDES Coronary Stent System (in trials, not FDA/CE Mark approved).
