Precious Metal and Radiopaque
Marker Bands

Resonetics produces precious metal and radiopaque marker bands from thin wall seamless tubing in our facility in Switzerland. Marker bands are small medical rings used in various medical devices and applications, such as catheters and delivery systems.

The precious metals we work with include platinum, platinum-iridium, and gold. Over 70 years, we have developed a proprietary manufacturing process that guarantees high precision and a burr-free finish. We specialize in producing custom marker bands that will meet your exact specifications. We also have marker band components that can be purchased through our online store.

Precious Metal and Radiopaque Marker Band Applications

Precious metals are used in marker bands due to their radiopacity, meaning they’re visible in medical imaging, such as X-rays, so medical professionals know exactly where the medical devices are in a patient’s body.

Our precious metal and radiopaque marker bands are used in a variety of advanced medical devices and applications, including:

  • Catheters
  • Delivery Systems
  • Implants
  • Angioplasty
  • Angiography
