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.

Research reveals optimal duration of dual antiplatelet therapy after stent implantation

Patients who have a stent implanted to open a blocked coronary artery face dual risks of developing blood clots and of having excessive bleeding in the months following the procedure.

Tenecteplase injection after clot removal improves stroke recovery

Removing a blood clot from a large brain artery, then injecting the clot-dissolving drug tenecteplase into the artery resulted in stroke survivors being more likely to have better function 90 days after their stroke than those receiving standard clot removal, according to preliminary late-breaking science presented today at the American Stroke Association's International Stroke Conference 2025.

No extra benefit from mechanical clot removal over medications in some strokes

Removing a clot blocking a medium- or small-sized artery in the brain mechanically is a safe treatment for a common type of stroke; however, it did not lessen disability more than best medical treatment (including clot-busting medication if indicated) alone, according to preliminary late-breaking science presented today at the American Stroke Association's International Stroke Conference 2025.

Regular dental flossing linked to lower risk of stroke and irregular heartbeats

Flossing your teeth at least once a week may be linked to a lower risk of stroke caused by a blood clot blocking brain blood flow and irregular heartbeats, according to a preliminary study to be presented at the American Stroke Association's International Stroke Conference 2025.

Laser-textured stents offer promising solution for vascular diseases

The research team led by Dr. Hojeong Jeon and Dr. Hyung-Seop Han of the Biomaterials Research Center at the Korea Institute of Science and Technology (KIST, President Oh Sang-Rok), along with Dr. Indong Jun from KIST Europe, has developed a novel stent surface treatment technology using laser patterning.

Hypertension drug may reduce heart failure risk in people recovering from heart attack

New research found that the medication spironolactone, often prescribed for hypertension (high blood pressure), may reduce the risk of heart failure in people recovering from a heart attack.

New robotic system could revolutionize treatment of multi-site conditions

Multiple disease sites are common in clinical practice. In the brain for instance, blocked blood vessels can cause strokes, in which the lack of oxygen rapidly damages brain cells.

Artificial cilia system monitors mucus conditions in human airways

Xiaoguang Dong, assistant professor of mechanical engineering, is leading a team of researchers that has developed a system of artificial cilia capable of monitoring mucus conditions in human airways to better detect infection, airway obstruction, or the severity of diseases like Cystic Fibrosis (CF), Chronic Obstructive Pulmonary Diseases (COPD) and lung cancer.

Hourglass-shaped stent shows promise for treating microvascular disease

A study at Mayo Clinic suggests that an hourglass-shaped stent could improve blood flow and ease severe and reoccurring chest pain in people with microvascular disease.

New stent sensor developed to detect blockages early

Stents to treat various blockages in the human body can themselves become blocked, but a new sensor developed at the University of Michigan for stents that are used in the bile duct may one day help doctors detect and treat stent blockages early, helping keep patients healthier.

Study finds no benefit of routine orbital atherectomy in cardiac stenting

Routine use of an orbital atherectomy device to remove calcium from severely blocked coronary arteries before patients undergo cardiac stenting procedures does not improve outcomes, a Mount Sinai-led study has found.

Tiny magnetic soft robots pave the way for targeted drug delivery

A team of scientists at Nanyang Technological University, Singapore (NTU Singapore) has developed grain-sized soft robots that can be controlled using magnetic fields for targeted drug delivery, paving the way to possible improved therapies in future.

MSU researchers test new nanotherapy infusion to target arterial inflammation

Inflammation of the arteries is a primary precursor and driver of cardiovascular disease - the No. 1 killer of people in the United States. This inflammation is associated with the buildup of dangerous plaque inside the arteries.

Tiny magnetic nanorobots show promise for treating brain aneurysms

Researchers have created nanoscale robots which could be used to manage bleeds in the brain caused by aneurysms.

Complete revascularization proves effective for older STEMI patients in first 4 years

The benefits of complete revascularization over culprit-only coronary artery revascularisation were confirmed in older patients with ST-segment elevation myocardial infarction (STEMI) and multivessel disease over the first 4 years, according to late-breaking research presented in a Hot Line session today at ESC Congress 2024.

Invasive strategy shows no benefit in cardiovascular death reduction for older NSTEMI patients

An invasive strategy vs. optimal medical therapy alone after a non-ST-elevation myocardial infarction (NSTEMI) in older adults did not affect the combined risk of cardiovascular death or MI, although non-fatal MIs and subsequent revascularisation procedures were reduced, according to late-breaking research presented in a Hot Line session today at ESC Congress 2024.

Research suggests flexible approach to antiplatelet management after drug-eluting stent implantation

Among patients undergoing non-cardiac surgery more than 1 year after coronary drug-eluting stent (DES) implantation, there was no difference with respect to ischaemic outcomes or major bleeding between perioperative aspirin monotherapy and receiving no antiplatelet therapy, according to late-breaking research presented in a Hot Line session today at ESC Congress 2024.
