A bare-metal stent is a stent made of thin, uncoated (bare) metal wire that has been formed into a mesh-like tube. The first stents licensed for use in cardiac arteries were bare metal – often 316L stainless steel. More recent "second generation" bare-metal stents have been made of cobalt chromium alloy. [1]
The vast majority of stents used in modern interventional cardiology are drug-eluting stents (DES). They are used in a medical procedure called percutaneous coronary intervention (PCI). Coronary stents are divided into two broad types: drug-eluting and bare metal stents. As of 2023, drug-eluting stents were used in more than 90% of all PCI ...
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.
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 antiproliferative drugs are released slowly over time to help ...
Bare metal stents were found to cause in-stent restenosis as a result of neointimal hyperplasia and stent thrombosis, which led to the invention of drug-eluting stents with anti-proliferative drugs to combat in-stent restenosis. [1]
In this position, the interventional cardiologist can inject contrast and visualize the flow through the vessel. If necessary, the physician can utilize percutaneous coronary intervention techniques, including the use of a stent (either bare-metal or drug-eluting) to open the blocked vessel and restore appropriate blood flow. In general ...
Newer generations of drug-eluting stents have been found to reduce the risk of restenosis, myocardial infarction, and death when compared with bare-metal stents. [65] Advancements in stent design that include reducing strut thickness have shown further improvements for patients compared to previous generations. [65]
Thus, coronary artery stents were created to prevent restenosis after balloon dilation. [4] There are three types of stents: bare-metal stents (BMS), drug-eluting stents (DES), and bioresorbable vascular scaffolds (BRS). [4] The first stents created were bare-metal stents where they were made from stainless steel and had poor flexibility.
