Understanding Marker Bands in Medical Technology
Marker bands are essential components in modern medical devices, providing critical visibility and precision during minimally invasive procedures. These small metallic rings are integrated into catheters, guidewires, and implants to enhance real-time tracking under imaging systems like X-ray, fluoroscopy, and MRI.
Why Marker Bands Matter
- Enhanced Visibility – Radiopaque materials create clear imaging markers
- Precision Placement – Helps guide devices to exact treatment locations
- Safety Improvement – Reduces procedural risks and complications
- Procedure Efficiency – Enables faster, more accurate interventions
