The device description explicitly states that the Neo Markers and Neo Marker Base are needed for the Marker Detection scanning method, which are physical components.
Based on the provided information, the Neo ADVISE™ System 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.
- Neo ADVISE™ System Function: The Neo ADVISE™ System is a surgical planning and guidance tool used during surgery. It uses optical scanning of implanted screws to assist the surgeon in estimating rod length, visualizing rod positioning, and creating a rod bending template. It does not analyze any biological specimens from the patient.
Therefore, the Neo ADVISE™ System falls under the category of surgical planning and guidance systems, not In Vitro Diagnostics.

Device Description
The Neo ADVISE system is a tool that supports the surgeon in open and percutaneous spinal surgeries performed with the Neo Medical Pedicle Screw System (K222256). After the placement of the pedicle screws, the software scans the the screw head positions and shows them in Augmented Reality (AR) on an iPad. Based on the scanned screw positions, the software displays the distance between the screw heads and calculates the minimum rod length. The surgeon can select any of the pre-bent or straight rods of the Neo PSS and check the placement of the rod in the patient's body without touching the body or taking X-Ray images. The software calculates the distance between the screw head and the rod in the coronal and sagittal plane for the selected rod, indicating possible screw head adjustments.
Again, based on the scanned screw position, the software can generate a custom bent rod template that follows the path through all screw heads. This provides the surgeon with a rod template that assists the surgeon in rod bending. The rod template is displayed in a 1-1 scale on the device in the sagittal and coronal plane, allowing the surgeon to copy the rod shape according to the template.
The scanning of the screw heads can be performed using two distinct scanning methods, 3D scanning and Marker detection. 3D Scanning does not require any additional hardware. The surgeon scans each guide separately by overlaying the physical guide with a virtual guide in AR. 3D Scanning of the guides is limited to 10 guides. The Marker Detection scanning method allows the scanning of up to 20 guides. This is achieved by the use of the Neo Markers and the Neo Marker Base. The Neo Markers are attached to each guide, providing the software with a defined pattern, similar to QR codes, that can be recognized by the software.
The Neo ADVISE System consists of several components. The software runs on an Apple iPad, which is put into a sterile bag to allow use in the sterile environment of the patient's area. The Neo Markers and the Neo Marker Base are needed to allow the scanning of the guides using the Marker Detection scanning method.

Summary of Performance Studies
Non-clinical testing included two cadaver studies, a usability study including a follow-up study and bench testing.
The first cadaver study utilized a biomechanical pilot study design with a single human cadaveric spine specimen. 11 German orthopedic and trauma surgeons participated. One investigator inserted 6 polyaxial pedicle screws (Neo Pedicle Screw SystemTM) percutaneously at levels L1-S1 on one side of the spine, resulting in instrumentation across 5 levels for fusion.
The second cadaver study aimed to assess the accuracy and effectiveness of the Neo ADVISE™ System in assembling and fixing posterior screw-rod constructions in thoraco-lumbo-sacral spine fusion surgery. Using CBCT (Cone-beam computed tomography systems) scans, primary endpoints measured translation of screw heads along sagittal and transverse axes, as well as angular change (Cobb angle) along sagittal and coronal planes. Four German spine surgeons conducted the study, demonstrating that AR-guided surgery maintained anatomy during rod placement and fixation.
The usability studies focused on identifying preventable errors attributable to device design or labeling and affirmed the usability of the Neo ADVISE™ system.
No clinical tests have been submitted.

Augmented Reality (AR) on an iPad. Based on the scanned screw positions, the software displays the distance between the screw heads and calculates the minimum rod length. The surgeon can select any of the pre-bent or straight rods of the Neo PSS and check the placement of the rod in the patient's body without touching the body or taking X-Ray images.

V. INDICATIONS FOR USE
The Neo ADVISE™ System is indicated to calculate the relative positions and distances between implanted Neo Pedicle Screw System™ screws, as estimated by visually identifying screw quides, to estimate rod length, visualize rod positioning, and create a rod template that can be used to visually quide the manually creation a contoured rod by the surqeon, with a mechanical rod bender. The Neo ADVISE™ System can be used in posterior open or percutaneous spine surgery in the thoracic, lumbar, and/or sacral spine when using the Neo Pedicle Screw System™.
VI. INDICATIONS FOR USE COMPARISON
Both the Neo ADVISE System and the predicate Bendini Spinal Rod Bending System are used to locate the screw position during spinal surgery and relative to the identified positions, generate bend instructions to shape a spinal rod.
The Neo ADVISE System is intended to be used with off-the-shelf rod benders while the Bendini system has a dedicated rod bending instrument.
The Bendini system can be used with any pedicle screw system while the Neo ADVISE System is dedicated for use with the Neo Pedicle Screw System (K222256) only.
Like the NuVasive Bendini Spinal Rod Bending System the Neo ADVISE System is intraoperatively digitizing the relative location of anatomical landmarks (i.e. the position of the pedicle screws), through the use of a camera and markers that are pre-fixed on the screw guides (same as the pointer stylus with NuVasive Bendini).
The differences in the indications for use are not critical to the intended surgical use of the devices as in both cases, a final intra-operative X-ray must be taken to confirm the spinal rod placement at the end of the procedure.
VII. TECHNOLOGICAL COMPARISON
Augmented reality and optical/electromagnetic localizer systems share similarities in their use during orthopedic surgery. The Neo ADVISE System's software utilizes the augmented reality functionality of an Apple iPad to scan the position of guides and pedicle screws, without the need for traditional tracking arrays or pre-operative data planning. Instead, markers may be used to
5
enhance object recognition. The Apple iPad's camera and sensors provide the interface for communication between the user and the software.
Similarly, the predicate device cleared under K122742 also uses a localized pointer or stylus to intraoperatively digitize the relative location of anatomical landmarks, which are then interpreted by proprietary algorithms, in place of the stereotaxic principle.
VIII. PERFORMANCE DATA
Non-clinical testing included two cadaver studies to evaluate the Neo ADVISE System, a usability study including a follow-up study to evaluate the human factors/usability aspects of the Neo ADVISE System, and bench testing.
The first cadaver study, conducted by 11 German orthopedic and trauma surgeons, utilized a biomechanical pilot study design with a single human cadayeric spine specimen. One investigator inserted 6 polyaxial pedicle screws (Neo Pedicle Screw SystemTM) percutaneously at levels L1-S1 on one side of the spine, resulting in instrumentation across 5 levels for fusion.
The second cadaver study aimed to assess the accuracy and effectiveness of the Neo ADVISE™ System in assembling and fixing posterior screw-rod constructions in thoraco-lumbo-sacral spine fusion surgery. Using CBCT (Cone-beam computed tomography systems) scans, primary endpoints measured translation of screw heads along sagittal and transverse axes, as well as angular change (Cobb angle) along sagittal and coronal planes. Four German spine surgeons conducted the study, demonstrating that AR-guided surgery maintained anatomy during rod placement and fixation.
The usability studies of the Neo ADVISE System's device-user interface, focused on identifying preventable errors attributable to device design or labeling and affirmed the usability of the Neo ADVISE™ system.
No clinical tests have been submitted.
IX. CONCLUSION
Based on equivalence of indications for use, technology characteristics and operational principle the substantial equivalence between the new and the predicate device has been demonstrated. The Neo ADVISE System, is at least as safe and effective as the legally marketed predicate Nuvasive Bendini Spinal Rod Bending System.
