Julio Palmaz, an interventional vascular radiologist, is known for inventing the balloon-expandable stent, for which he received a patent filed in 1985.
It is "Stents" and not stets. Stents are small, metallic, porous cylindrical structures that are placed within a blood vessel to prevent re-narrowing of the blood vessel due to chloesterol deposition. Usually these stents are placed after a "ballon angioplasty", a medical surgery to clean the deposited cholesterol plaques in the blood vessels (coronary arteries), to prevent re-narrowing or furhter deposition of chlolesterol that may block the coronary arteries and may lead to Angina or heart attack. In some cases these stents may also be coated with drugs such stents are called as drug eluting stents.
coronary arteries, the carotid arteries in the neck, and renal (kidney) or biliary (gall bladder) arteries
Stent placement is part of more than 70% of interventional procedures.
This patient has had coronary artery bypass grafting. This is an open heart surgery. In the surgery, the patient got 4 of their heart arteries replaced with stents. Stents help restore blood flow to the heart. This surgery was secondary to coronary artery disease, which is when the arteries of the heart get hardened with plaque.
A metal tube put into a coronary artery to hold it open.
Coronary stents last forever and will never be removed. However, 10-20% of patients may develop retenosis, or blockage in he stent, which would require another procedure to clear them out. For this reason it is very important for patients who have been treated with Stents to take Plavix and Aspirin as prescribed by their doctor until told otherwise.
Stents do not cure angina; instead, they are used to relieve symptoms associated with coronary artery disease. By opening narrowed or blocked arteries, stents improve blood flow to the heart, which can reduce angina episodes. However, they do not address the underlying causes of heart disease, so ongoing management and lifestyle changes are often necessary.
Charles Theodore Dotter invented the first coronary stent in 1969,and planted in a dog to make a trial.
These coated stents have significantly reduced restenosis rates--down to 3%--in some clinical studies. One coated stent brand, the Cordis CYPHER, became the first coated stent approved by the FDA in April 2003.
