NDI Passive Spheres

The Original IGS Sphere

Designed by NDI more than 14 years ago for use with the Polaris optical tracking system, single-use NDI Passive Spheres are the original passive sphere for IGS systems. NDI Passive Spheres are compatible with most Image-Guided Surgery (IGS) systems available today and mount to standard snap-on posts.

Procedure Trays

NDI's Procedure Trays are designed to meet the specific needs of common IGS procedures, simplify ordering, and maximize stock within limited storage space. NDI's Procedure Trays feature:

Procedure Matched Quantities -
Procedure Trays contain the exact number of spheres required 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 -
Reduces risk of spheres being dropped or popping out of package when opened.

'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.

Sterile

NDI Spheres are sterilized and ready to use.
