Visibility
Trilogy markers are ultrasound visible from the time of deployment. Permanent visibility in ultrasound, mammography, and MRI* simplifies patient follow-up across imaging modalities.
Accuracy
Trilogy markers expand upon deployment and are designed to resist migration and attach to tissue. Trilogy markers are easily placed with single-handed percutaneous deployment system.
Performance
Trilogy is precision engineered of implant-grade materials for long-term performance and is non-bioresorbable. Trilogy markers are constructed of shape-memory Nitinol embedded in a flexible imaging-enhanced low-density polyethylene (LDPE) polymer.
Marker Materials
Trilogy Markers are constructed of implant-grade materials, consisting of a metal shape embedded in a flexible imaging-enhanced polymer. These materials include:
| Metal Shape: | Trilogy metal shape is made of nitinol. |
| Polymer: | Trilogy flexible polymer is a unique compound made of low-density polyethylene (LDPE), glass microspheres, and iron nanoparticles for imaging enhancement. |
Trilogy Markers contain Nickel.
Trilogy Deployment System
Trilogy Markers are pre-loaded in an ergonomic percutaneous deployment system for easy, accurate, single-handed placement of Trilogy markers.

- Slide feature for easy marker deployment.
- Sharp 14ga x 10cm cannula
- Shape identification feature
- Echogenic cannula tip and cm depth marks for accurate placement under ultrasound.
Marker Deployment Simulation

Markers expand upon deployment for three-dimensional visualization and migration resistance.
