Intended Use

SYMPHONY Navigation Ready Instruments: The SYMPHONY Navigation Ready Instruments when used with the compatible Universal Navigation Adaptor Set are intended to assist the surgeon in locating anatomical structures in either open or percutaneous procedures. These are indicated for use in surgical spinal procedures, in which: · the use of SYMPHONY OCT System is indicated. · the use of stereotactic surgery may be appropriate, and · reference to a rigid anatomical structure, such as 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 which includes tracking arrays supplied by the navigation system manufacturer. These procedures include but are not limited to spinal fusion. The SYMPHONY Navigation Ready Instruments require manual calibration with the Medtronic StealthStation navigation system. The SYMPHONY Navigation Ready Instruments are intended to support cervical and thoracic polyaxial screw placement. Universal Navigation Adaptor Set: The Universal Navigation Adaptor Set (UNAS) is intended for use with the compatible DePuy Synthes Navigation Ready Instruments to assist the surgeon in locating anatomical structures in either open or percutaneous procedures. These are indicated for use 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 which includes tracking arrays supplied by the navigation system manufacturer.

The DePuy Synthes Navigation Ready Instrument, when used with UNAS, requires manual calibration with the Medtronic StealthStation navigation system.

Device Story

SYMPHONY Navigation Ready Instruments (drills, trocars, probes, taps, screwdrivers) and Universal Navigation Adaptor Set (UNAS) facilitate surgical spinal procedures; instruments attach to Medtronic StealthStation navigation system via Navigation Ring ST and SureTrak II passive tracking arrays. Surgeon performs manual calibration; system tracks instrument position/trajectory relative to patient anatomy (CT, MR, or fluoroscopic images). Output provides real-time visual guidance for screw placement; assists surgeon in locating anatomical structures. Used in OR by surgeons; enhances precision of spinal instrumentation; supports cervical/thoracic polyaxial screw placement.

Clinical Evidence

Bench testing only. Accuracy verification included toggle analysis (positional/angular deviation) and length comparison. Simulated use evaluation performed in sawbones models; instruments assembled with UNAS and Medtronic tracking arrays, manually calibrated, and navigated to prepare pedicle/lateral mass holes and insert screws. Final screw position compared against post-operative scans and sawbones model to confirm performance.

Technological Characteristics

Reusable orthopedic stereotaxic instruments (drills, trocars, probes, taps, screwdrivers) and navigation adaptor. Materials: stainless steel, anodized aluminum, silicone rubber. Connectivity: passive tracking via Medtronic SureTrak II arrays. Manual calibration required with Medtronic StealthStation. No internal software/algorithm; relies on external navigation system.

Indications for Use

Indicated for patients undergoing surgical spinal procedures (e.g., spinal fusion) requiring stereotactic navigation for cervical and thoracic polyaxial screw placement or anatomical localization in open/percutaneous procedures.

Regulatory Classification

Identification

## SYMPHONY Navigation Ready Instruments:

The SYMPHONY Navigation Ready Instruments are reusable instruments used for the preparation for and insertion of SYMPHONY OCT screws, in either open or percutaneous procedures. These instruments are designed for navigated and nonnavigated use. Navigation of these instruments is achieved using the DePuy Synthes Universal Navigation Adaptor Set (UNAS). For further details on UNAS, refer to the UNAS labeling.

- Implant/instrument mating conditions ●
- . Simulated Use Evaluation. SYMPHONY Navigation Ready Instruments were assembled with UNAS and with the Medtronic tracking arrays, manually calibrated and navigated. As a result, holes in pedicles and lateral masses of cervical and thoracic spine were prepared and SYMPHONY screws were inserted in a sawbones model. Final screw position in the software was compared with post-operative scan and sawbones model.
