balloon-expandable stent
Vascular stent deployed by inflating a balloon catheter to expand the device.
Full Definition
A type of vascular stent that is deployed by inflating a balloon catheter on which the stent is pre-mounted. The balloon expansion plastically deforms the stent material, typically stainless steel or cobalt-chromium alloy, causing it to expand to its predetermined diameter and permanently conform to the vessel wall. These stents offer precise deployment control and high radial strength, making them ideal for focal stenoses in relatively straight vessels. The deployment pressure and final diameter can be controlled by balloon inflation parameters, allowing for optimal vessel apposition and lesion coverage.
Usage
Usage note: Specify stent dimensions and deployment pressure in procedural reports.
