Read the full statement (211 words)
Navigation Enabled Instruments are reusable instruments indicated to be used during the preparation and placement of DePuy Synthes screws during spinal surgery to assist the surgeon in precisely locating anatomical structures in either open or percutaneous procedures. The Navigation Enabled Instruments are designed for use with only the specific DePuy Synthes implant system(s) for which they are indicated and with the Medtronic StealthStation® System. The Navigation Enabled Instruments are indicated for use in surgical spinal procedures, in which:
• the use of EXPEDIUM 4.5, EXPEDIUM 5.5, EXPEDIUM 6.35, VIPER 2, VIPER SAI, EXPEDIUM VERSE, VIPER PRIME (without stylet control), SYMPHONY OCT and the TriALTIS Spine System is indicated,
• the use of stereotactic surgery may be appropriate, and
• reference to a rigid anatomical structure, such as the pelvis or a vertebra, 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.
These procedures include but are not limited to spinal fusion. The Navigation Enabled Instruments are also compatible with DePuy Synthes Power Systems and the Medtronic IPC® POWEREASE System.
The Navigation Enabled Instruments used in conjunction with the SYMPHONY OCT System are intended to support indicated cervical and thoracic polyaxial screw placement only.
Indications for use as stated in the FDA summary.
