What is it indicated for?
The ATEC Posterior Navigated Disc Prep Instruments are indicated to facilitate discectomy, bony resection, implant selection, and access during spinal surgery. Navigated instruments are specifically designed for use with the Medtronic® StealthStation™ System, which is indicated for any medical condition in which the use of stereotactic surgery may be appropriate and where reference to a rigid anatomical structure, such as vertebra, can be identified relative to a CT or MR based model, fluoroscopy images, or digitized landmarks of the anatomy.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
