  2. Coronary stent - Wikipedia

    en.wikipedia.org/wiki/Coronary_stent

    Coronary artery stents, typically a metal framework, can be placed inside the artery to help keep it open. However, as the stent is a foreign object (not native to the body), it incites an immune response. This may cause scar tissue (cell proliferation) to rapidly grow over the stent and cause a neointimal hyperplasia.

  3. Stent - Wikipedia

    en.wikipedia.org/wiki/Stent

    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. [1]

  4. Percutaneous coronary intervention - Wikipedia

    en.wikipedia.org/wiki/Percutaneous_coronary...

    Percutaneous coronary intervention (PCI) is a minimally invasive non-surgical procedure used to treat narrowing of the coronary arteries of the heart found in coronary artery disease. [2] The procedure is used to place and deploy coronary stents, a permanent wire-meshed tube, to open narrowed coronary arteries. PCI is considered 'non-surgical ...

  5. Drug-eluting stent - Wikipedia

    en.wikipedia.org/wiki/Drug-eluting_stent

    [56] [57] [58] Specifically, drug-eluting stents are used in the treatment of various medical conditions usually at the site of stenotic or occlusive arterial lesions, but one of the primary medical uses is in the treatment of coronary artery disease. [59] Stents are inserted into narrowed coronary arteries, where the narrowing is primarily ...

  6. Angioplasty - Wikipedia

    en.wikipedia.org/wiki/Angioplasty

    A coronary angioplasty is a therapeutic procedure to treat the stenotic (narrowed) coronary arteries of the heart found in coronary heart disease. [1] These stenotic segments of the coronary arteries arise due to the buildup of cholesterol -laden plaques that form in a condition known as atherosclerosis . [ 3 ]

  7. Bioresorbable stent - Wikipedia

    en.wikipedia.org/wiki/Bioresorbable_stent

    Like metal stents, placement of a bioresorbable stent will restore blood flow and support the vessel through the healing process. However, in the case of a bioresorbable stent, the stent will gradually resorb and be benignly cleared from the body, enabling a natural reconstruction of the arterial wall and restoration of vascular function. [6]

  8. Cypher stent - Wikipedia

    en.wikipedia.org/wiki/Cypher_stent

    During a balloon angioplasty, the stent is inserted into the artery to provide a "scaffold" to open the artery. 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 ...

  9. Cardiology - Wikipedia

    en.wikipedia.org/wiki/Cardiology

    Coronary circulation is the circulation of blood in the blood vessels of the heart muscle (the myocardium). The vessels that deliver oxygen-rich blood to the myocardium are known as coronary arteries. The vessels that remove the deoxygenated blood from the heart muscle are known as cardiac veins.
