Surgical tube

STENT

This mesh-like device is often placed inside a blood vessel or airway to keep it open after a blockage.

A "stent" is a small mesh tube surgeons insert into arteries or ducts to keep them open, often after a blockage. The clue plays it straight—no wordplay or tricks—just a direct definition for a common medical device. If you’ve heard of heart stents, that’s the same idea: a tiny scaffold to improve blood flow. Simple and literal.
