Polaris Vega® ST

Enable new OEM surgical instrument tracking and navigation applications with this versatile optical measurement solution that can be used in almost any operative environment.

Our Versatile Optical Track that Supports Diverse OEM Surgical Applications

Our versatile optical tracker, the Polaris Vega® ST provides trusted optical measurement that supports accurate and reliable 3D tracking in a variety of OEM surgical applications, in almost any clinical environment. Tracking is achieved via navigation markers that can be attached to OEM surgical instruments such as probes, shavers, awls, drills, microdebriders, and more.

Exclusive to the Polaris Vega ST is an available Radiation Hardening option. The Radiation Hardening option protects the optical tracker from gamma and neutron radiation by way of a shielded processor and modified memory management. This extra protection allows the Polaris Vega ST to be safely integrated into OEM surgical navigation systems and workflows that are used in radiation therapy suites.

More customization options are available to enhance system utility and flexibility. The Positioning Laser assists with positioning the optical tracker and/or surgical equipment within the measurement volume. The Extended Pyramid Volume nearly doubles the measurement volume, which benefits procedures that require a clear view of several surgical instruments at once.

NDI tracking and measurement products are general metrology components that can be integrated into customer products, research experiments, and/or as components of medical devices that require precision measurement and tracking. While NDI components and technology can be integrated into original equipment manufacturer (OEM) medical devices, they are not specifically intended for a given application and, as such, have not been developed or manufactured in accordance with medical device standards. It remains the responsibility of the OEM customer or end-user to determine and test the suitability of NDI components and technology for their intended use, including performing any required ethics approval, verification, and validation required to demonstrate suitability and compliance. System-level testing, certification, and validation are the responsibility of the original equipment manufacturer or the applicable end-user and should be completed prior to the use of NDI products or technologies in any application.
