radiopaque marker
Metallic indicators on medical devices that provide visibility under fluoroscopy during vascular procedures.
Full Definition
Radiopaque markers are small metallic elements embedded in or attached to vascular intervention devices such as stents, balloons, and catheters. These markers, typically made of platinum, gold, or tantalum, appear as bright spots on fluoroscopic imaging, allowing interventionalists to precisely position devices and assess deployment. The visibility of these markers is crucial for accurate stent placement and ensuring complete lesion coverage during percutaneous interventions.
Usage
Usage note: Often abbreviated as 'markers' in procedural notes, but full term should be used in formal documentation.
In Context
- "The radiopaque markers on the balloon catheter allowed precise positioning across the stenotic segment." — Procedural report
