Overview
Stent is wired tubular structure with balloon expansion or self expansion capability made up of metal or fabric.

Stent is used to restore blood flow through narrowed or blocked arteries. Another application of stent is to improve blood flow and to
prevent the weakened artery from bursting. Stent is used in coronary arteries, central and peripheral arteries and veins, bile ducts,
esophagus, colon, trachea or large bronchi, ureters, and urethra.

In the early 1990’s bare metal stents were developed. This was pioneered by Julio Palmaz, a physician-inventor. The bare metal
stent was a huge leap forward in treating the problem of restenosis. Like angioplasty, the stent is inserted percutaneously through the
femoral artery and then is expanded in the coronary vessel. Having the stent in place, holding open the artery, decreased the
restenosis rate to roughly 20-25% instead of 40%.

In the late 1990’s the first drug eluting stents (DES) were developed as a solution to the problem of restenosis. Drug eluting stents
are now replacing conventional stents as the dominant therapy for coronary artery disease. In 2004, DES was estimated to reach
utilization in 87% of all angioplasty procedures, an amazing penetration rate given DES had only been launched one year earlier.
DES has already achieved a 0% restenosis rate in many cases.

Recently bioabsorbable stents are used widely because they disappear after time and foreign substance will not remain in the body.
Bioabsorbable stents would be less invasive because they disappear after time and the foreign substance will not remain the body.
