The stent is inserted into the artery with the balloon-tip catheter. When the stent is correctly positioned in the coronary artery, the balloon is inflated, expanding the stent against the walls of the coronary artery.

Coronary Stenting who invented the first coronary artery stent?
Charles Theodore Dotter invented the first coronary stent in 1969，and planted in a dog to make a trial.
What is a stent in a OM branch of the circumflex coronary artery?
A stent is best described as a tiny metal scaffold that holds open coronary arteries to prevent atherosclerosis and therefore heart attacks (in that artery only). They actually look a little bit like the spring in pens if you take them apart. OM just means (obtuse marginal) branch of the circumflex. The circumflex is a larger artery that wraps around the heart. These are just descriptions of where exactly the stent is placed for future reference.
Your mother had a stent placed in her ramus artery?
The ramus artery is also know as the left intermediary artery.
When does someone need heart stents?
The coronary stent is a tube placed in the coronary arteries to keep them open and is a treatment for coronary heart disease. It is an intervention to prevent heart attacks and more damage to the heart.
What is the use of a coronary stent?
To open an artery near the heart
Is a coronary stent artificial?
A coronary stent is an artificial support device placed in the coronary artery to keep the vessel open after treatment for coronary artery disease.
Is a coronary stent a human organ?
A coronary stent is an artificial support device placed in the coronary artery to keep the vessel open after treatment for coronary artery disease.
What does a coronary stent do?
By forming a rigid support, the stent can prevent restenosis and reduce the need for coronary bypass surgery.
Coronary artery stent?
A coronary artery stent is a small, metal mesh tube that is placed inside a coronary artery to help keep the artery open. To place the stent, a small incision is made in the groin area to reach the artery there. A catheter is guided through the groin artery into an area of the coronary artery which is blocked. The stent is inserted along with a balloon catheter and expands when the balloon is inflated. The stent is then left there to help keep the artery open.Reviewed ByReview Date: 03/21/2009David C.

When was the Cordis CYPHER Coronary Artery Stent approved by the FDA?
The drug-eluting coronary artery stent, the Cordis CYPHER, made by CYPHER, a Johnson & Johnson company, became the first coated stent approved by the FDA in April 2003.
Where in the body is a cardiac stent placed?
A coronary stent (or cardiac stent) is placed in arteries that supply blood to the heart. The stent is a tube that is designed to keep the arteries open to increase blood flow.

What is risk factor of plaque breaking off during a stent placement in a coronary artery?
It all depends on the cardiovascular health of the individual.To minimize the chances of blood clots, surgeons prescribe blood thinning medication after they insert a stent in a coronary artery.

Inserting A Coronary Artery Stent?
Sometimes the coronary artery becomes weakened, often due to the pressure put on it if there is a buildup of fat or other deposits nearby. Sometimes the coronary artery begins to deteriorate because of genetic factors. In either case the patient's doctor may recommend the insertion of a coronary stent, which strengthens this small artery and allows it to once again perform its job efficiently, namely to supply the heart itself with blood.Widening the Coronary ArteryA narrowed coronary presents a major problem because blood flow to the heart is decreased. A stent can be placed in the artery to widen it and allow easier passage of blood. This type of stent is very specialized in its design, consisting of a small metal mesh style tube that will act as a scaffolding for the blood vessel. In this type of surgery a balloon catheter is used to insert the stent into the damaged artery and the tip of the balloon is inflated to allow expansion of the stent itself. The catheter balloon is then deflated and removed, and the stent is now permanently fixed in the artery, which heals itself around the metal.Performing A Balloon AngioplastyThis procedure is used to actually push fatty material out of the center of the artery and is often performed in conjunction with the insertion of a heart stent. Inflating the catheter actually pushes the fatty matter into the walls of the artery and thereby widens the blood vessel. However if the widening process is liable to weaken the blood vessel wall, it can be strengthened by the use of the mesh tube, or stent.Stents With Medicated SurfacesSome procedures involve the insertion of a stent that is medicated, and this type of stent is used when it is determined that the healing process needs to be accelerated soon after the surgery. In some patients the coronary artery narrows at various points and the stent will be used to widen most of this passageway, but if there is a chance of reblockage, also known as restenosis, the medication contained in the stent will help heal the entire vessel wall and combat this possibility.A stent is used only when it is deemed necessary that the coronary artery wall is too weak to withstand the pressure of the blood flow. The coronary artery weakens if there is a buildup of fatty deposits or LDL cholesterol in the bloodstream, and the reduced supply of nutrients and oxygen to the heart causes serious degradation of the heart muscle tissue. A stent helps to prevent this constricted flow of blood, but is only one of several options available for repairing a constricted coronary artery.
What is a ptca of the lad and rca with intracoronary stenting?
Okay first anatomy. The LAD is the Left Anterior descending artery. It provides the front (anterior) wall of the heart with blood. The RCA is the Right Coronary Artery, and provides the back (inferior) wall of the heart with blood So now the procedures. The PTCA stand for PercuTaneous Coronary Angioplasty. This mens that they inflated a balloon to clear blockage, and didn't place a stent. The intracoronary stent, just means they placed a stent in the artery. I have included a link of a YouTube video.
