What is a Nitinol Stent? A nitinol stent is a medical device a doctor may insert to open a patient's blood vessel to relieve a blockage and promote the free flow of blood through the vessel. A number of conditions may call for the use of a stent to reduce the risks of stroke, myocardial infarction, and other potential issues associated with limited blood flow and blocked blood vessels.

- In about a third of patients who’ve had angioplasty without a stent, the artery that was opened begins to become narrowed again within months of the procedure. This renarrowing is called restenosis. A stent is a tiny wire mesh tube. It props open an artery and is left there permanently.

- Arteries are blood vessels that carry blood away from your heart to other parts of your body. A stent is placed in an artery as part of a procedure called percutaneous coronary intervention (PCI), also known as coronary angioplasty. PCI restores blood flow through narrow or blocked arteries. A stent helps support the inner wall of the artery in the months or years after PCI. Doctors also may place stents in weak arteries to improve blood flow and help prevent the arteries from bursting. Stents usually are made of metal mesh, but sometimes they're made of fabric. Fabric stents, also called stent grafts, are used in larger arteries.

How much does angioplasty with stents cost in top Indian hospitals for foreigners? They include: Balloon: A catheter with a small balloon tip is guided to the narrowing in your artery. Once in place, the balloon is inflated to push the plaque and stretch the artery open to boost blood flow to the heart. Stent: This is a small tube that acts as a scaffold to support the inside your coronary artery. A balloon catheter, placed over a guide wire, puts the stent into your narrowed coronary artery. Once in place, the balloon is inflated, and the stent expands to the size of the artery and holds it open.

Stent Placement What is a stent placement? A stent is a wire mesh stainless steel tube that holds an artery open and keeps it from closing again. It becomes a permanent part of your artery. Why is it necessary? Fatty deposits can block blood flow through arteries and cause pain. A piece may break off, form a clot, and cause a heart attack or stroke. A stent opens the blockage and keeps it open, which allows blood to flow smoothly. Good blood flow reduces pain and risks of clots forming. How is it done?

Coronary stenting Coronary stenting. Definition. A coronary stent is an artificial support device placed in the coronary artery to keep the vessel open after treatment for coronary artery disease. Also called atherosclerosis, coronary artery disease is a build-up of fatty matter and debris on the walls of the arteries.

A Doctorâs Treasury of Stents are small expandable tubes used to treat narrowed or weakened arteries in the body. In patients with coronary heart disease, caused by the buildup of plaque, stents are used to open narrowed arteries and help reduce symptoms such as chest pain (angina) or to help treat a heart attack.

nyyun928 - Cardiovascular System Nitroprusside (Nipride) and nitroglycerin (Tridil) are commonly used to decrease both preload (ventricular end-diastolic pressure) and afterload (vascular resistance). These vasodilators reduce blood return to the heart and decrease systemic peripheral vascular resistance.

Heart Stent Problems ­. Heart stents are small wire-mesh tubes which are used to keep previously clogged arteries open. Following heart bypass surgery and angioplasty, the stents are left in the artery to prevent it from re-closing. Stents gained widespread use in the medical community during the 1990s. Original designs were bare metal devices inserted into the arteries.

How long will a heart stent last? Many of these lesions recur and the artery has another obstruction within a short period. This occurs in 40 percent of angioplasties within six months after PTCA. A stent is a short hollow tube. It is placed in the artery at the site of the former blockage. It holds the artery open. Initially, bare metal stents were used. Compared with no stents, re-obstruction rates at six months after angioplasty were cut in half, to 20 percent, and few re-obstructions were seen more than a year after treatment. Drug eluting stents, or DES, were developed to try to further reduce the rate of re-obstruction. These stents are metal with a polymer coating and a drug, either sirolimus or paclitaxel, mixed into the polymer. The drug is delivered to the area of the opened artery over a period of up to a year.

Heart disease guide A balloon catheter, placed over a guide wire, puts the stent into your narrowed coronary artery. Once in place, the balloon is inflated, and the stent expands to the size of the artery and holds it open. The balloon is then deflated and removed while the stent stays in place. Over several weeks, your artery heals around the stent. These are often placed during angioplasty to help keep the coronary artery open. The stent is usually made of metal and is permanent. It can also be made of a material that the body absorbs over time.
