Read the full statement (207 words)
The TELIGEN System is indicated to provide minimally invasive access, visualization, illumination, magnification and discectomy of the surgical area of the spine.
The TELIGEN Access Probe and TELIGEN Clear are Navigation Ready Instruments and when used with the compatible Universal Navigation Adaptor Set (UNAS) are intended to assist the surgeon in locating anatomical structures in either open or percutaneous procedures. The navigation feature is used in surgical spinal procedures, in which:
• the use of stereotactic surgery may be appropriate, and
• reference to a rigid anatomical structure, such as the pelvis or a vertebrae can be identified relative to the acquired image (CT, MR, 2D fluoroscopic image or 3D fluoroscopic image reconstruction) and/or an image data based model of the anatomy using a navigation system and associated tracking arrays.
These procedures include but are not limited to spinal fusion. TELIGEN Clear, when used with UNAS, can be pre-calibrated with the Brainlab Navigation System. TELIGEN Access Probe, when used with UNAS, can be pre-calibrated with the Brainlab Navigation System, where other navigation systems require manual calibration and tracking arrays supplied by the navigation system manufacturer.
The TELIGEN Access Probe is indicated for stimulation of peripheral motor nerves, including spinal nerve roots, for location and identification during surgery.
Indications for use as stated in the FDA summary.
