What are the different types of metal stent?
stents, small tubes used in medical procedures to open blocked or tapered arteries or veins, can be covered with drugs or left. They can be made of fabric, plastic or metal. Unbeaped metal stents made of wire tissues are called "bare metal" stents. The stents that are covered with drugs are called "drug-trapped" or "Eluting drugs", stents. Coated and unloaded stents with wire mesh are used to treat specific diseases or body conditions. Clinical studies have found that the use of stents of eluting drugs for levering arteries has helped reduce the amount of reblocking more than the use of an unpacked metal stent. For example, separate stents used to treat esophageal cancer are shaped as small cylinders. They are made of flexible rows of cross pedal, which allows the cylinder to be easily extended or repaired. Separate stents can be made of plastic or metal and can ethutate drugs to carry medicines for chemotherapy.
A relatively new type of unpacked metal stent with a wire network is covered with titanium alloy, which allows the stent to be better tolerated by the body's immune response system; This stent is called "bioactive" stent. Another type of stent of wire mesh or vascular stent can be coated with a radioactive material for the treatment of specific cancer sites. Both untouched metal stent and stent Eluting drugs can be used in virtually any part of the body, including chest, chest, abdomen, esophagus, urinary urinary and other areas to maintain life processes. Peripheral stents used to unblock or dilation of veins or arteries in attachments can also be covered or unpacked.
Coronary stent is for the treatment of heart disease. IOPLASTICS Angposules is one method used to unblock and/or dilation of arteries in the heart or coronary system. For angioplastic treatment were used bothCoated wire network, so unloaded metal stents. Sometimes tears may develop in the aorta and stents have been used to repair these tears or to strengthen the weakened lining of the aorta.
The main advantage of using stents, whether bare metal or eLuting drugs, to treat heart disease is that they help prevent re -narrowing or blocking coronary arteries because the stents remain after the angioplastic procedure. This narrowing after arterial repair is called restenosis. Unlike an ordinary metal stent, the stent contains a drug ethging a drug that helps prevent blood clots that could block the stent artery again. Drug coated stents also help reduce the effects of body reactions on permanently placed stents.
