Detailed Answer:
Hello,
Thanks for trusting Healthcaremagic!
I have gone through your query and I can understand your concerns.

Cardiac stents or coronary stents are small expandable tubes that are placed in the coronary arteries that supply blood to the heart to keep them open. They are usually made of metal and of size ranging from 3 to 4 mm in diameter and few centimeters in length. It look like a tiny wire mesh tube on a closer look.
There are newer kind of medicated stents that deliver small amount of medicines to prevent re stenosis in the future.

Stents are inserted by a procedure called angioplasty. It is performed under local anesthesia and mild sedation. It is a vascular procedure done through your femoral vessels (blood vessels on your thigh), A catheter is introduced through your blood vessels to reach up to the heart and stent is inserted to your coronary vessels(blood vessel supply your heart). The procedure involve no major incision and take less than one hour. You can leave the hospital on the next day.
Hope I have answered your query.
Feel free to ask if you have any further queries.
Wishing you good health.

Thanks
Dr.Shinas
