NDI Passive Sphere™ (snap-fit post)

The industry’s original—and world’s leading—passive marker sphere, the NDI Passive Sphere™ is a sterile, single-use reflective sphere. NDI Passive Spheres* are attached to OEM surgical instruments, where they act as triangulation points for the instrument within the 3D operative space. • Coated in a special retro-reflective surface that consists of tens of thousands of microbeads that act like precision lenses to reflect IR light. • Delivers reliable tracking across different procedures thanks to consistent sphere shape, surface, and placement. • Mounts on standard snap-on sphere posts, with an audible click that ensures secure attachment. For threaded sphere posts, the Disposable Reflective Marker Sphere is also available. • Packaged in procedural trays that contain the exact number of spheres required by the surgical navigation procedure. • Situated in deep-seated tray pockets that make it easy to remove spheres without dropping or dumping. *The NDI Passive Sphere is an FDA-regulated medical device.
