  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. Bioresorbable stent - Wikipedia

    en.wikipedia.org/wiki/Bioresorbable_stent

    A bioresorbable stent is a tube-like device that is used to open and widen clogged heart arteries and then dissolves or is absorbed by the body. It is made from a material that can release a drug to prevent scar tissue growth. It can also restore normal vessel function and avoid long-term complications of metal stents. [1] [2]

    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.

    For some high-risk cardiovascular patients with stents, the often-recommended practice of prolonged taking of aspirin might be ineffective, and in some cases, even harmful, a new study found.

  7. Percutaneous coronary intervention - Wikipedia

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

    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 ...

  8. Restenosis - Wikipedia

    en.wikipedia.org/wiki/Restenosis

    The 2006 SIROCCO trial compared the sirolimus drug-eluting stent with a bare nitinol stent for atherosclerotic lesions of the subsartorial artery, reporting restenosis at 2 year follow-up was 22.9% and 21.1%, respectively. [21] A 2009 study compared bare nitinol stents with percutaneous transluminal angioplasty (PTA) in subsartorial artery ...

  9. Artificial heart valve - Wikipedia

    en.wikipedia.org/wiki/Artificial_heart_valve

    Blood clots can be hazardous because they can lodge in, and block, downstream arteries (e.g. coronary arteries, leading to heart attack [myocardial infarction]; or cerebral arteries, leading to stroke). A desirable characteristic of artificial heart valves is that they are non- or minimally thrombogenic.
