The description focuses on 3D rendering, visualization, navigation data integration, and guidance tools based on pre-operative planning and real-time tracking. There is no mention of algorithms that learn from data or perform tasks typically associated with AI/ML, such as image analysis for automated feature detection, predictive modeling, or adaptive guidance based on learned patterns. The "Not Found" entries for mentions of AI/ML and descriptions of training/test sets further support this conclusion.
No
Explanation: The device is a surgical planning and visualization tool, providing guidance and enhanced visualization for spinal surgeries, but it does not directly treat or prevent a disease or condition.
No
Explanation: The device is intended for surgical planning and visualization, utilizing 2D medical images to create a 3D scene for surgical guidance during spinal procedures. It does not perform any diagnostic function.
No
While the core functionality is software, the device description and performance studies explicitly mention and validate the use of specific AR headsets (HoloLens2 and Magic Leap 1) and their performance characteristics (FOV, resolution, latency, etc.), indicating a reliance on and integration with specific hardware components beyond a standard PC. The EMC and wireless coexistence testing also cover these hardware components.
Based on the provided information, the SpineAR SNAP is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- SpineAR SNAP's Function: The SpineAR SNAP is a software-based device used for pre-operative and intraoperative surgical planning and visualization. It processes medical images (CT, MR, XA) and navigation data to assist surgeons during spinal procedures. It does not analyze biological specimens.
- Intended Use: The intended use clearly states its purpose is for surgical planning and visualization, not for analyzing samples from the body.
- Device Description: The description focuses on image processing, 3D scene creation, guidance tools, and integration with navigation systems, all related to surgical procedures on the patient's body.
Therefore, the SpineAR SNAP falls under the category of a surgical planning and navigation system, not an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
SpineAR SNAP is intended for use or pre-operative surgical planning on-screen and in a virtual environment, and intraoperative surgical planning and visualization on-screen and in an augment using the HoloLens2 and Magic Leap 1 AR headset displays with validated navigation systems as identified in the device labeling.
SpineAR SNAP is indicated for spinal stereotaxic surgery, and where reference to a rigid anatomical structure, such as the spine, can be identified relative to images of the anatomy. SpineAR is intended for use in spinal implant procedures, such as Pedicle Screw Placement, in the lumbar and thoracic regions with the Magic Leap 1 AR headset, and in the lumbar region with the HoloLens2 AR headset.
The virtual display should not be relied upon solely for absolute positional information and should always be used in conjunction with the displayed 2D stereotaxic information.

Device Description
The SpineAR SNAP does not require any custom hardware and is a software-based device that runs on a high-performance desktop PC assembled using "commercial off-the-shelf" components that meet minimum performance requirements.
The SpineAR SNAP software transforms 2D medical images into a dynamic interactive 3D scene with multiple point of views for viewing on a high-definition (HD) touch screen monitor. The surgeon prepares a pre-operative plan for stereotaxic spine surgery by inserting guidance objects such as directional markers and virtual screws into the 3D scene. Surgical planning tools and functions are available on-screen and when using a virtual reality (VR) headset. The use of a VR headset for preoperative surgical planning further increases the surgeon's immersion level in the 3D scene by providing a 3D stereoscopic display of the same 3D scene displayed on the touch screen monitor.
By interfacing to a 3rd party navigation system such as a Medtronic StealthStation S8, the SpineAR SNAP extracts the navigation data (i.e. tool position and orientation) and presents the navigation data into the advanced interactive, high quality 3D image, with multiple point of views on a high-definition (HD) touch screen monitor. Once connected, the surgeon can then execute the plan through the intraoperative use of the SpineAR SNAP's enhanced visualization and guidance tools.
The SpineAR SNAP supports three (3) guidance options from which the surgeon selects the level of guidance that will be shown in the 3D scene. The guidance options are dotted line (indicates deviation distance), orientation line (indicates both distance and angular deviation), and ILS (indicates both distance and angular deviation using crosshairs). Visual color-coded cues indicate alignment of the tracker tip to the guidance object (e.g. green = aligned).
The 3D scene with guidance tools can also be streamed into an AR wireless headset (Magic Leap 1 or HoloLens2) worn by the surgeon during surgery. The 3D scene and guidance shown within the AR headset is projected above the patient and does not obstruct the surgeons view of the surgical space.

Summary of Technological Characteristics
The SpineAR SNAP is similar in its technological features to its predicate device, the StealthStation S8 Spine Software v1.3.0 (K201189). Both systems are indicated for spinal stereotaxic surgery, and where reference to a rigid anatomical structure, such as the spine, can be identified relative to images of the anatomy.
The SpineAR SNAP does not include any of the physical stereotaxic instrumentation, including camera system, and relies on the positional information supplied by the connected navigation system (e.g. Medtronic StealthStation S8 system with StealthStation Spine Software v1.3.0) to track the position of the surgical instruments relative to the surgical anatomy.
The SpineAR SNAP includes an AR headset that displays the 2D images and 3D scene including navigation and enhanced guidance information in an AR wireless headset (e.g. Microsoft HoloLens2) worn by the surgeon. The predicate device displays 2D and 3D images including navigation information with minimal guidance on a system monitor, and does not support use of AR headset.

Performance Data
The following non-clinical performance testing was conducted to evaluate the subject device to ensure the SpineAR SNAP meets its intended use and performance requirements.
- Software Verification and Validation was performed to test the software requirements specifications for the SpineAR SNAP.
- Human Factors and Usability Validation demonstrated that the intended users of a SpineAR SNAP can safely and effectively perform tasks for the intended uses in the expected use environments, i.e. intraoperative use of the AR headsets. Validation took place under conditions of simulated use with users providing feedback on the usability of the software for performing defined tasks.
- Navigation Accuracy testing was conducted to demonstrate that SpineAR does not negatively affect the navigation accuracy of the connected Medtronic StealthStation 8 surgical navigation system. The final placement of each screw in a spine model was assessed via a post-surgical CT scan and compared to the pre-surgical plan to calculate the absolute displacement of the screw tip and absolute angular error of the screw. The summary of accuracy test results below demonstrate performance in 3D positional and trajectory accuracy that is within the system accuracy of the StealthStation S8 (mean positional error
