What is a Coronary Artery stent?
A coronary stent is stainless tube with slots. It is mounted on a balloon catheter in a "crimped" or collapsed state. When the balloon of is inflated, the stent expands or opens up and pushes itself against the inner wall of the coronary artery. This holds the artery open when the balloon is deflated and removed.

What To Expect Before a Stent Procedure?
Most stent procedures require an overnight stay in the hospital and someone to take you home. Discuss with your doctor:
- • When to stop eating and drinking before coming to the hospital
- • What medicines you should or shouldn't take on the day of the procedure
- • When to come to the hospital and where to go
If you have diabetes, kidney disease, or other conditions, talk with your doctor about whether you need to take any extra steps during or after the procedure to avoid complications.
Before the procedure, your doctor may talk with you about medicines you'll probably need to take after the stent is placed. These medicines help prevent blood clots from forming.
It's important that you know how long you should take these medicines and why they're important.

What To Expect During a Stent Procedure
For Arteries Narrowed by Plaque
This procedure usually takes about an hour. It could take longer if stents are inserted into more than one artery during the procedure.
Before the procedure starts, you'll get medicine to help you relax. You'll be on your back and awake during the procedure so you can follow the doctor's instructions.
The area where the catheter is inserted will be numbed, and you won't feel the doctor threading the catheter, balloon, or stent inside the artery. You may feel some pain when the balloon is expanded to push the stent into place.
For Aortic Aneurysms
This procedure takes a few hours. It usually requires a 2- to 3-day stay in the hospital.
Before the procedure, you'll be given medicine to help you relax. If a stent is placed in the abdominal aorta, your doctor may give medicine to numb the area, but you'll be awake during the procedure.
If a stent is placed in the chest portion of the aorta, your doctor will likely give you medicine to make you sleep through the procedure.
Once you're numbed or asleep, your doctor will make a small cut in your groin (upper thigh). He or she will insert a catheter into the blood vessel through this cut.
Sometimes, two cuts (one in the groin area of each leg) are needed to place fabric stents that come in two parts. You will not feel the doctor threading the catheter, balloon, or stent into the artery.
