Answer:
A stent is a small mesh tube that holds open passages in the body, such as weak or narrow arteries. Stents are often used to treat narrowed coronary arteries that supply the heart with oxygen-rich blood. The stent holds open the narrowed arteries to allow adequate blood to flow to the heart.
