Stents are metallic mesh coils that are used to open the narrowed or blocked passageways in the body. There are different types of stents used for varied purposes.
They have revolutionized the treatment of coronary heart diseases and many other medical conditions involving the blockage of passageways by minimizing the invasive treatment for the conditions that once required surgery.
Stents may be used to open up the narrowed coronary arteries that supply the heart, cerebral arteries that supply the brain, or renal arteries supplying the kidneys. They are available in varied sizes depending upon the size of the blood vessel.
