NaviNetics Frame System

Stereotactic neurosurgical procedures are constrained by the costs and limitations of commercially available stereotactic devices. Our challenge was to develop a robust, low complexity stereotactic device that could be used for multiple stereotactic and functional neurosurgical applications including deep brain stimulation (DBS).

Our Stereotactic System

NaviNetics has developed an FDA cleared system to reduce the burden of establishing the stereotactic coordinate system for both the surgeon and the patient. In place of the typical head ring of frame-based systems, a small anchor key is affixed to the patient’s skull with percutaneous screws. This system is designed to be more comfortable for the patient and keeps the facial area free from obstruction. Throughout the procedure, components can be attached and removed from the skull anchor key, giving the surgical team more flexibility and space to work. From the imaging and planning steps to adjustment of the head frame, the key makes it faster and easier for surgeons to precisely target and access intracranial sites and decreases the amount of equipment attached to the patient over the course of the procedure.

The main components of the system include a stereotactic head frame, the skull anchor key, an MR localizer, a CT Localizer, X-ray reticles, a mechanical microdrive, and DBS lead implantation accessories.

The Stereotactic Frame

This frame was designed with the patient in mind. The stereotactic head frame, which attaches to the skull anchor key, is a robust stereotactic frame that is more lightweight than other commercially available frame-based devices to improve an awake patient’s comfort throughout the surgical procedure. Classified as an arc centered stereotactic device, the procedure to direct instruments and/or electrodes to a specific desired target using 3D guidance is familiar to functional neurosurgeons. It provides three linear degrees of freedom (X, Y and Z axes) for target positioning, with two angles of rotation to optimize approach trajectory. The compact design places all adjustments in close proximity to the surgical field, improving surgeon experience.
