NDI Passive Spheres

A single-use, sterile 11.8 mm passive marker sphere that is compatible with OEM surgical instruments with snap-fit mounting posts.

The Industry’s Original, and World’s Leading, Passive Marker Sphere

Originally developed by NDI for use with the Polaris optical tracking system, single-use NDI Passive Spheres are widely used with IGS systems worldwide. NDI Passive Spheres are compatible with a wide range of Image-Guided Surgery (IGS) systems and mount to standard snap-on posts.

Procedure Trays

Procedure Matched Quantities
Procedure Trays contain the exact number of spheres typically used in the most common IGS procedures and eliminate the need to open multiple packages for one procedure. Ordering and inventory management are vastly simplified by ordering one package for one procedure.

Deep Seated Spheres with Protective Lid

Deep-seated sphere trays with protective lids help keep spheres secure during handling.

‘Serving Tray’ Handling

Spheres are easily picked out of trays—no dumping required. Less handling reduces potential reflective coating damage.

Space Optimization

Procedure Trays use considerably less supply room or automated vending machine storage space than other spheres packaging. An audible click confirms secure attachment to the snap-on mounting post.
