No
The summary describes automated recognition and registration of a physical object (Navigation Cube) within medical images, which is a common image processing task and does not explicitly mention or imply the use of AI/ML algorithms. The planning of the needle trajectory is described as manual or based on calculations from the registered cube and virtual needle, not through learned patterns or predictions.
No
The device is a non-invasive software intended for planning the needle trajectory of CT-guided, percutaneous punctures, providing information for the physician but not directly performing a therapeutic function.
No
The device is a non-invasive software intended for planning the needle trajectory of CT-guided, percutaneous punctures. While it can be used for punctures aimed at diagnostic purposes, it itself does not perform any diagnostic function; it only aids in the planning of a procedure that could be diagnostic. It also explicitly states it integrates "diagnostic Medical Imaging Viewer medDream," implying medDream is the diagnostic component, not Cube Navigator itself.
No
The device description explicitly states that Cube Navigator "requires a CT-scan with a Navigation Cube mounted on a patient for the purposes of visualization" and that it is used "in combination with a Navigation Cube". The Navigation Cubes are described as separate, physical devices (sterile, disposable needle guides). While the Cube Navigator software performs the planning, it is dependent on and interacts with a specific hardware component (the Navigation Cube) to fulfill its intended use. Therefore, it is not a software-only medical device.
Based on the provided text, the Cube Navigator device is not an In Vitro Diagnostic (IVD).
Here's why:
- Definition of IVD: An IVD is a medical device used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health.
- Cube Navigator's Function: The Cube Navigator is a software used for planning the trajectory of a needle for percutaneous punctures. It uses medical images (CT scans) and a physical device (Navigation Cube) attached to the patient. It does not analyze biological samples.
- Intended Use: The intended use is for planning needle trajectories for therapeutic and diagnostic procedures, not for performing diagnostic tests on samples.
- Device Description: The description focuses on image processing, registration of the Navigation Cube, and displaying planning information. It does not mention any analysis of biological materials.
While the procedure itself can be for diagnostic purposes (e.g., obtaining a tissue sample), the Cube Navigator software's role is in the planning of the procedure, not in the analysis of the sample obtained.

Intended Use / Indications for Use
Cube Navigator is a non-invasive software intended for planning the needle trajectory of CT-guided, percutaneous punctures using DICOM-images and a Navigation Cube attached to a patient. It is indicated for the planning the needle trajectory of CT-guided, percutaneous punctures for therapeutic and diagnostic purposes. The software's functionality allows to automatically recognize orientation, position and type of the Navigation Cube present in the DICOM-images and to manually define virtual needle trajectories to a physician-identified target through the Navigation Cube. Based on this planning, Cube Navigator provides physician information for such purpose.
Cube Navigator can only be used in combination with a Navigation Cube, specifically, either the Access Cube for instruments 10-20G (article number mt-ac-ct-20, Class 1 exempt, product code GDF) or the Puncture Cube for instruments 18-22G (article number mt-pc-ct-25, Class 1 exempt, product code GDF). Cube Navigator is a standalone software that integrates the CE-marked and FDA-cleared diagnostic Medical Imaging Viewer medDream manufactured by Softneta that provides all DICOM-related functionality like displaying and manipulating DICOM-images.

Device Description
Cube Navigator is a non-invasive medical device software used in interventional radiology for planning the needle trajectory of CTguided, percutaneous punctures. Cube Navigator provides planning functionality for needle placement through a separate device, called a Navigation Cube. Cube Navigator allows the user to register the Navigation Cube in a feasible needle traiectory using a virtual needle. Based on this planned trainctor displays needle depth and the enty points on the Navigation Cube in its user interface. The Cube Navigator software is only used for planning the needle trajectory, but requires a CT-scan with a Navigation Cube mounted on a patient for the purposes of visualization.
Navigation Cubes are sterile, disposable needle quides which are attached to the planning scan is acquired. Currently two variants exist: Puncture Cube or Access Cube, both Class 1 exempt, product code GDF. The Navigation Cubes support the use of needle sizes 10-20G (Access Cube) or 18-22G (Puncture Cube), Needle length is dependent on the trained from the displayed needle depth. Cube Navigator detects which Navigation Cube is present in the takes the average of the supported needle diameters for that Navigation Cube when calculating the thickness of the virtual needle.
Cube Navigator is a standalone software that integrates with the CE-marked and FDA-cleared diagnostic Medical Imaging Viewer medDream manufactured by Softneta (Class II, K22232), see Software Architecture Design Cube Navigator for integrated version). Gube Navigator allows the user to access the functionality of medicing images locally or through a remote DICOM-connection, by viewing and manipulating DICOM-images through the user interfaces of the Cube Navigator, as well as accessing the functionality of Cube Navigator itself. The DICOM integration is part of the base software package medDream (see the Statement recarding the DICOM-Standard - Cube Navigator for detailed information about DICOM conformity).
Cube Navigator as well as the Navigation Cubes are manufactured by Medical Templates AG. medDream is manufactured by Softneta and for the described purpose, distributed by Medical Templates AG as bundle together with Cube Navigator. When the user installs Cube Navigator, medDream is also installed, without any additional installation or configuration necessary.

Verification of automated registration accuracy: Data from phantom studies and retrospectively collected patient cases are used to determine the accuracy of the registration tool to automatically detect and register Navigation of displayed needle depth.
Side by side comparison to interactively define virtual needle path for planning: The needle planning capability of the software end is verified by scanning an existing puncture, registering the cube, planning the virtual needle in the same trajectory as the physical one and comparing if the suggested coordinates for the needle plan by the software are equal to the actual coordinates used for the physical needle. For each cube 5 datasets from different tests or studies have been selected.
Summary of Performance Studies
Non-Clinical Tests:
- Verification of automated registration accuracy: Data from phantom studies and retrospectively collected patient cases were used to determine the accuracy of the registration tool.
- Verification of displayed needle depth: A dataset was loaded, the cube registered, and the needle trajectory planned. The calculated needle-depth was verified by measuring the tip of the needle to the corresponding plate in the cube with the line measurement tool provided by MedDream (FDA certified product), comparing the two values to determine the error of the indicated needle length.
- Side by side comparison to interactively define virtual needle path for planning: The needle planning capability was verified by scanning an existing puncture, registering the cube, planning a virtual needle in the same trajectory as the physical one, and comparing if the suggested coordinates for the needle plan by the software were equal to the actual coordinates used for the physical needle. For each cube, 5 datasets from different tests or studies were selected. The results showed that for all cases, the needle coordinates suggested by the software coincided with the actual coordinates for the physical setup.
- Usability study: 5 interventional radiologists from independent sites used the software to plan an intervention successfully and provided feedback.

Indications for Use Comparison
21 CFR 807.92(a)(5)
The Cube Navigator has substantially equivalent Intended Use as the predicate device, in that it is a software application that allows the user to define a virtual needle path in the displayed DICOM-images and provides information to the user for treatment planning. In comparison to the Indications For Use of the provides functionality for the planning of needle paths as one of many functions, the Cube Navigator software is limited to be used for such planning of needle paths as described in the Indication for Use Statement. The differences in the Indications for use stem from that limitation. Therefor the Indications for Use do not affect the safety and effectiveness of the device when used as labeled.

Technological Comparison
21 CFR 807.92(a)(6)
Cube Navigator software and the predicate device, are both software tools that enable the user to plan a virtual needle path in the displayed DICOM-images. While the predicate is an image analysis software application for reviewing body imaging studies that also provides functionality for that purpose, the Cube Navigator provides only functionality for that purpose. To achieve the existing DICOM-Viewer MedDream (Class II, K222320, manufactured by Softneta UAB) on which the planning functionality is based, In comparison to the predicate device functionality of the Cube Navigator is limited to the features relevant for the planning. Therefor this difference in features does not raise different questions of safety and effectiveness. As those features on t present in the Cube Navigator are possibly associated with risks regarding safety and effectiveness, this difference in features rather leaves the Cube Navigator associated with less risks overall in comparison to the predicate device.
Another difference in functional features is that the Cube Navigator provides information based on the user's defined needle path, that helps the user understand through which holes of the virtual needle is currently going and what the corresponding virtual needle is. The information provided is based on the registration performed as a first step in the process of planning and the user's input to define the virtual needle. In principle risks may arise from a faulty
5
registration, which is a risk that is also relevant for the automated registration for viewing and analyzing multiple timepoint volume datasets, a feature provided by the predicate device. Another source of potential risk is the virtual needle path planning, that is also a feature in the predicate device the user need to manually determine through which holes of the Navigation Cube the current virtual needle depth is. The Cube Navigator provides this information for the user and therefor simplifies this process thereby erasing potential source of error due to human error. Therefor this difference in features does not raise different questions of safety and effectiveness. Cube Navigator has the predicate device and is substantially equivalent in performance. Any technological differences do not raise any new potential safety risk. In conclusion the Cube Navigator software is substantially equivalent to the predicate device.
Non-Clinical and/or Clinical Tests Summary & Conclusions 21 CFR 807.92(b)
Verification of automated registration accuracy:Data from phantom studies and retrospectively collected patient cases are used to determine the accuracy of the registration tool to automatically detect and register Navigation of displayed needle depth:In order to verify the needle length in the sidebar a dataset is loaded, the cube is registered and the needle traiectory is planned. The calculated needle-depth is verfied by measuring the tip of the needle to the corresponding plate in the cube with the ine measurement tool provided by MedDream (FDA certified product). By comparing the two values to each other the error of the indicated needle length is determined .Side by side comparison to interactively define virtual needle path for planning The needle planning capability of the software end is verified by scanning an existing puncture, registering the cube, planning the virtual needle in the same trajectory as the physical one and comparing if the suggested coordinates for the needle plan by the software are equal to the actual coordinates used for the physical needle. This provides the advantage that it can be done retrospectively on existing data and excludes effects not related to the software such as actual puncturing by the clinician. For each cube 5 datasets from different tests or studies have been selected and the above conducted process has shown that for all cases the needle coordinates suggested by the software coincide with the actual coordinates for the physical setup. It is worth mentioning that apart from suggesting the correct coordinates for the needle plan (holes and corners) the accuracy of the physical puncture is mostly related to the physical design of the cube and its coordinate arids (holes and corners). With regards to needle diameter an average needle qauqe of 0.9 mm for Puncture Cube and 1.2 mm for Access Cube is used in the software as simulations have shown that accuracy only varies slightly for the different needle diameters. Usability study was conducted where 5 interventional radiologists from independent sites used the software to plan a intervention successfully and provided feedback along the line of the system. It was shown that the Cube Navigator is safe and effective to use.
No clinical tests have been submitted, referenced. or relied on in the premarket notification submission of substantial equivalence.
Based on the non-clinical test conducted we find Cube Navigator to be as safe, as effective and performs as well as the predicate device.
