Heart stents are used to treat coronary artery disease is a small tube-shaped device made of thin metal mesh. Procedure, during percutaneous coronary intervention, called a stent to expand the artery, are inserted into the blocked coronary artery previously left open for the purpose. Heart Stents Often, balloon catheter was inserted into the narrowed artery mechanical procedure is, the expansion is inserted into the coronary artery narrowed.In during the angioplasty procedure to widen the artery. After the larger artery stent, a balloon catheter is attached so that you can put it down. Through which the catheter is usually made in the femoral artery in the groin or arm is inserted into an incision. Device, carefully dissected, that is threaded along the artery until it reaches that part of the heart artery stenosis. Pressurized water is passed through the catheter to widen an artery and inflating the balloon stent. When the position and stability of the stent, the balloon catheter is removed by contract. Cardiac stent placement is a permanent solution to the problem of not always narrowed arteries. One problem, the stent can trigger a response from the patient's immune system can potentially have a foreign object. This response usually leads to the development of scar tissue that can narrow the artery stents involve, involve inflammation. This inflammation, drug-eluting stent, known as cardiac stents have been developed to solve this problem location.A can promote the formation of a new type of blood clot Mino Noshi. The first stent used is called a bare-metal stents, and bare wire. Drug-eluting stent is a bare-metal stents coated with antiproliferative drugs film. The stent is in place, will start releasing small amounts of drugs to reduce the rate of cell proliferation at the site it gradually. This will reduce the strength of the immune response to the stent to help prevent scar tissue from forming.
