Vascular stent
A tubular metal-mesh device, either balloon-expandable or self-expanding, designed for permanent implantation within a vessel to keep its lumen open.
How it is used
Used to treat significant arterial stenoses after angioplasty, providing structural support that prevents re-narrowing (restenosis).
Clinical tip
The choice between a balloon-expandable or self-expanding stent depends on the anatomical location and the expected external mechanical forces on the vessel.
