A drug-eluting stent (DES) is a small mesh tube that is placed in the arteries to keep them open in the treatment of vascular disease.The stent slowly releases a drug to block cell proliferation (a biological process of cell growth and division), thus preventing the arterial narrowing that can occur after stent implantation.
A coronary stent is a tube-shaped device placed in the coronary arteries that supply blood to the heart, to keep the arteries open in patients suffering from coronary heart disease. The vast majority of stents used in modern interventional cardiology are drug-eluting stents (DES).
Cypher is a brand of drug-eluting coronary stent from Cordis Corporation, a Cardinal Health company. During a balloon angioplasty , the stent is inserted into the artery to provide a "scaffold" to open the artery.
A coronary stent placed by percutaneous coronary intervention. Older bare-metal stents (BMS) provide a mechanical framework that holds the artery wall open, preventing stenosis, or narrowing, of coronary arteries. Newer drug-eluting stents (DES) are traditional stents with a polymer coating containing drugs that prevent cell proliferation. The ...
The Absorb naturally dissolving stent has also been investigated in single-arm trials and in randomized trials comparing it to a drug-eluting stent. Early and late major adverse cardiac events, revascularizations, and scaffold thromboses have been uncommon and similar to the Xience DES, a market leader in the drug eluting stent category.
A dual therapy stent is a coronary artery stent that combines the technology of an antibody-coated stent and a drug-eluting stent. [1] Currently, second-generation drug-eluting stents require long-term use of dual-antiplatelet therapy , which increases the risk of major bleeding occurrences in patients. [ 2 ]
The region has seen notable progress in catheter-based technologies, imaging techniques, and stent designs, which together enhance the accuracy, safety, and success rates of interventions. Drug-eluting stents (DES), bioresorbable vascular scaffolds and occludes, and newer iterations of drug-coated balloons are widely used, with more advanced ...
Coronary stents are placed during a coronary angioplasty. The most common use for coronary stents is in the coronary arteries, into which a bare-metal stent, a drug-eluting stent, a bioabsorbable stent, a dual-therapy stent (combination of both drug and bioengineered stent), or occasionally a covered stent is inserted.
