balloon-expandable stent
Vascular stent that requires balloon inflation for deployment and expansion against vessel walls.
Full Definition
A balloon-expandable stent is a type of endovascular device consisting of a metallic mesh tube mounted on a balloon catheter that expands when the balloon is inflated. These stents are designed to provide structural support to blood vessels after angioplasty, preventing elastic recoil and reducing restenosis rates. The balloon inflation process allows for precise control of stent diameter and ensures optimal apposition against the vessel wall. This technology is widely used in coronary and peripheral vascular interventions, with various designs optimized for different anatomical locations and lesion characteristics.
Usage
Usage note: Contrasts with self-expanding stents that deploy automatically upon sheath withdrawal.
