Predicate Device Information The Cube navigation system is substantially equivalent to the following predicate devices: - Fiagon Navigation system (K162176) primary ● - Fiagon Navigation system (K133573) secondary . ## 4. Device Description The Cube Navigation System is an image guided surgery system, visualizing instrument positions on preoperative scans (e.g., CT, MRI, fluoroscopy) utilizing electromagnetic tracking technology. The position of the instrument with integrated sensor and the patient equipped with localizers are localized within an electromagnetic field, generated by a field generator, called navigation sensor within the Cube navigation system. The principle of {4}------------------------------------------------ navigation is based on electromagnetic spatial measuring of localizer element in a generated electromagnetic field. The display of navigation information requires an image-to-patient registration procedure. During registration procedure, the navigation system determines the coordinate transformation between the intraoperative position of the patient and the position of the preoperative scan by surface matching performed by the user either tactile using an navigated instrument or non-tactile using the registration device VituEye. Thereafter the spation of the instrument is displayed superimposed to the image data. The navigation information is updated with a rate of 15 to 45 Hz. ## 5. Intended Use The Cube Navigation System and its components are intended as an aid for precisely locating anatomical structures in either open or percutaneous procedures. The Cube Navigation System is indicated for any medical condition in which the use of stereotactic surgery may be appropriate, and where reference to a rigid anatomical structure in the field of ENT surgery, such as the paranasal sinuses, mastoid anatomy, can be identified relative to a CT or MR based model of the anatomy.

Comparison of Technological Characteristics The Cube Navigation System is considered to be substantially equivalent to the previously cleared Fiagon Navigation system (K162176 and K133573). The system comprises modified components of Hardware and Software to previously cleared Fiagon Navigation System (K162176 and K133573) which do not change indications for use, intended use or performance and safety requirements. The functionality of the overall system remains equal to the Fiagon Navigation System. More details about identical and modified hardware and software are described subsequentially. {6}------------------------------------------------ The main difference of the new Cube navigation system to its predicates are mostly dimensional differences with aesthetic changes in the overall design and updated versions of internal computing hardware. Additionally, the Fiagon navigation system (predicate) allows for importing/loading image data from CD/DVD drive incorporated in the system. The Cube navigation system tracking technology, system components, registration methods, and system functionality however are identical to the primary predicate. One difference of the new Cube navigation system is that the new system offers an additional design and component as the navigation sensor (also known as field generator) for the system. The Navigation sensor NanoRest can be used as an alternative to the already cleared navigation sensor components with the predicate devices. The additional alternative NanoRest has the same technological characteristics and functionality as the other navigation sensor options. The generating device has a smaller working field with similar accuracy and the design allows adjusting the working field to include the relevant surgical area (similar as for the design of the predicates). Another difference of the new system is in the registration device used for non-tactile photo registration. The new Cube navigation system uses the VirtuEye component for photo registration where the camera and MapperFrame are designed into one device, where the primary predicate used two separate devices. Both versions use the same reference marker frame and underlying concept with the same algorithms. The modified device is compatible to a stereo camera to allow for taking pictures simultaneous, where the primary predicate is compatible to a single camera device for taking pictures sequencially. The Navigation software ENT released for the Cube navigation system is the latest release in the release history of the Fiagon navigation software ENT initially cleared for the predicates Fiagon Navigation systems. The visualization concept of the orthogonal slice images, the 3D model, the live video image and the status indicators in the software remained similar to the originally cleared Navigation Software ENT. The latest release for Cube Navigation systems has undergone a UI refresh with symbols and icons being updated for improved user visualization. The software features of the latest release of the navigation software ENT includes the similar set of functionalities of the predicate systems. Such as Recording function (recording sequences of screen contents), Screen shot function, Patient data loading via USB device, PACS Network, Image data fusion, Determine distances between two points in the data set, overlaying structures, Visualization parameters of the navigation display can be adjusted (instrument specific). Additionally, the Cube navigation system allows for removing artifacts from the 3D model (eye protection glasses) in order to use the dataset for registration. The different functionalities are supplementary functions and do not limit or change the main functionality of the system. {7}------------------------------------------------ The modifications do not raise new types of safety or effectiveness questions. Bench testing has been conducted to evaluate the proposed system, and results confirm that the device performs as intended and in a similar manner compared to the predicate. | Feature | Cube Navigation System | Fiagon Navigation<br>System [K162176] | Fiagon Navigation<br>System [K133573] | |-----------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------|--------------------------------------------------| | Class | Class II<br>21 CFR 882.4560<br>Product code: PGW | Class II<br>21 CFR 882.4560<br>Product code: PGW | Class II<br>21 CFR 882.4560<br>Product code: PGW | | Indications for<br>Use | (see above) | (see above) | (see above) | | Tracking<br>Method | Electromagnetic | Electromagnetic | Electromagnetic | | Field<br>generator | Mounted to headrest,<br>Integrated into headrest or<br>bedside mounted | Integrated into headrest<br>or bedside mounted | Integrated into headrest<br>or bedside mounted | | Method of<br>registration | Surface matching tactile<br>Surface matching photo | Surface matching tactile<br>Surface matching photo | Surface matching tactile | | System<br>accuracy<br>requirement | Mean bench accuracy:<br>Position Mean < 1.5mm | Mean bench accuracy:<br>Position Mean < 1.5mm | Mean bench accuracy:<br>Position Mean < 1.5mm | | Field<br>distortion<br>detecting<br>mechanism | Yes;<br>Field distortions are<br>detected<br>by redundant localizer<br>information and distorted<br>values are excluded from<br>displaying | same | same | | Instrument<br>verification | Instrument /Registration<br>verified after patient<br>registering.

Performance Data Tests were performed in order to prove the performance claims such as, device precision & accuracy, electrical safety, EMC and the electromagnetic field distortion detection mechanism. The following non-clinical tests were performed to determine substantial equivalence: - . Anatomy orientated accuracy bench testing for each instrument probe and localizer without registration in order to measure the instrument accuracy achieved with the Cube Navigation System itself. - Anatomy orientated accuracy bench testing after tactile registration photo based, ● non-tactile registration - Fields distorting handling bench testing ● - Electrical safety according to IEC 60601-1 and EMC testing according to IEC ● 60601-1-2 - The non-clinical data supports the safety and performance of the device, thus ● demonstrating that the Cube Navigation System performs as intended in the specified use conditions. - The non-clinical data demonstrates that the device performs comparably to the ● predicate device for the same intended use. ## 8. Conclusion Based on the indications for use, technological characteristics, performance testing, and comparison to the predicates, it is concluded that the Cube Navigation system is substantially equivalent to the predicate devices identified in this submission, and does not present any new issues of safety or effectiveness.
