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).
The drugs are thrombolytics and fibrinolytics used in a process called thrombolysis. Surgeries performed may be minimally-invasive endovascular procedures such as a percutaneous coronary intervention (PCI), which involves coronary angioplasty. The angioplasty uses the insertion of a balloon and/or stents to open up the artery. [1]
An anti-rejection-type medication, sirolimus, helps to limit the overgrowth of normal cells while the artery heals which reduces the chance of re-blockage in the treated area known as restenosis, and reduces the chances that another procedure is required. [1] [2] The Cypher stent was approved for use by the FDA in 2003. [2]
The FDA recently approved a heart stent made specifically for infants and young children, a device that could help kids born with certain congenital heart defects avoid a series of open heart ...
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.
