What is it indicated for?
RESPONSE™ Navigation Instruments are intended to be used during the preparation and placement of Response 4.5/5.0 and 5.5/6.0 Spine System pedicle screws during spinal surgery to assist the surgeon in precisely locating anatomical structures in open procedures. These instruments are designed for use with the Medtronic® Stealthstation® S8 System (V1.2.0), 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 as stated in the FDA summary.
