### Device Description
UroNav 3 is a medical image processing system that provides image-guided intervention and diagnostic information, which guides interventional instrumentation to targets that have been defined by the physician. The target can be indicated either pre-procedurally or intra-procedurally using images or relative to an indicated position on the patient. As a diagnostic system, it combines pre-procedural and intra-procedural imaging to assist in locating areas of interest detected on one set of images on the other. The system provides fusion between Ultrasound (US) and different imaging modalities such as Magnetic Resonance Imaging (MR), Computed Tomography (CT), etc. When used as a navigation aid, it also transforms two and three-dimensional patient images (scan sets) into dynamic representations on which a medical instrument can be navigated. The system performs spatial mapping from one image space to another image space or from image space to physical space ("registration") allowing the physician to correlate scan sets with each other and to the patient. The system facilitates minimally invasive interventional procedures. Images used by UroNav can include archived image data from a CD, PACS, etc., and live images from an ultrasound system.
The UroNav system consists of an Electromagnetic Measurement System (EMMS) (including a Field Generator, System Control Unit and System Interface Unit(s)), a System Unit (including a CPU/monitor, medical-grade power supply and mobile cart), Field Generator stand, UroNav software and various instrumentation devices. The UroNav System Unit and the UroNav software utilize the keyboard, mouse and visual display to interact with the image data from a connected Ultrasound System. This interaction includes the selection of targets and associated navigation on the UroNav monitor. Targeted use areas for UroNav include hospital operating rooms, outpatient surgery centers, ultrasound suites, and procedure rooms.
UroNav 3 is designed to display the 2D live video received from commercially available ultrasound machines and use this 2D video to reconstruct a 3D ultrasound image. The system has been designed to work with the clinicians' existing ultrasound machine, transrectal ultrasound (TRUS) probe, commercially available needle guides and needle gun combinations. Additional software features include patient data management, multiplanar reconstruction, segmentation, image measurement and 3D image registration. UroNav utilizes an electromagnetic measurement system (EMMS) for identifying and tracking the location of the TRUS probe (and associated needle quides, instruments, etc.) relative to the 2D and 3D images. The EMMS Field Generator is positioned near the patient and provides an electromagnetic (EM) field for detection by a proprietary electromagnetic (EM) Sensor, which is attached to the ultrasound probe and tracks probe position while the physician performs a normal ultrasound imaging procedure of the subject prostate. The Field Generator and EM Sensor are connected to the UroNav
{5}------------------------------------------------
System Control Unit and the PC running the UroNav software. Control of the ultrasound probe and ultrasound system is done manually by the physician, just as it would be in the absence of UroNav 3. However, by tracking the position and orientation of the ultrasound probe while capturing the video image, UroNav is able to reconstruct and display a 3D image and 3D rendered surface model of the prostate.
The reconstructed 3D image can be further processed to perform various measurements including volume estimation and can be examined for abnormalities by the physician. Patient information, notes and images may be stored for future retrieval.
Locations for biopsies, needles, markers, and other devices may be selected by the physician, displayed in the 3D image and 3D rendered surface model, and stored. Previously created 3D models may be recalled and may be aligned or registered to the current live display of the prostate. The 3D model used for co-reqistration may be based on another series of ultrasound images or DICOM images.
The physician may also attach a commercially available biopsy needle guide to the TRUS probe and use the probe and biopsy needle to perform tissue biopsy. Whenever the ultrasound machine is turned on by the physician, the live 2D ultrasound image is displayed on the UroNav display during the biopsy. As the TRUS probe with attached needle guide is maneuvered by the physician, the position and orientation of the probe is tracked. UroNav 3 is able to add, display and edit plans for target locations (e.g., biopsy sites) as well as an estimate of the probe position and needle trajectory relative to the 3D image and 3D rendered surface model of the prostate and the planned target locations. UroNav 3 offers the physician additional 3D information for assessing prostate abnormalities, planning and implementing biopsy procedures. The additional image processing features are generated with minimal changes to previous TRUS probe based procedures, and the physician always has access to the live 2D ultrasound image during prostate assessment or biopsy procedure.
In addition to standard transrectal procedures, UroNav 3 also supports transperineal access and commercially available gridplates normally used for performing such procedures. When using transperineal mode, the UroNav EM Sensors are attached to both the TRUS probe and the transperineal gridplate within a mechanical stepper assembly. Procedure planning, segmentation, registration and navigation are performed the same as the standard transrectal procedure except that a computer rendering of the transperineal gridplate is displayed on the UroNav 3 display. UroNav provides an indication of the gridplate coordinates that correspond to the identified target location.

# Predicate Device Information & Comparison
The design, function, and specifications of UroNav 3 are similar to the identified legally marketed predicate devices. Similar to UroNav (Version 2.0) and PercuNav, UroNav 3 provides image-guided interventional planning and navigation for prostate procedures, the ability to view and capture live 2D ultrasound data to create reconstructed 3D ultrasound images/models and the ability to fuse and register these images with those acquired and imported from other DICOM-based imaging devices. Similar to all of the above listed predicate devices, UroNav also performs other viewing and imageprocessing functions such as image registration, multi-planar reformats and includes tools to segment, measure and annotate images. Each of the devices can also output selected image views, processed data and user-defined reports.
UroNav 3, UroNav (Version 2.0) and PercuNav utilize the identical commercially available Electromagnetic Measurement System (EMMS) for procedure navigation and tracking. UroNav and PercuNav also share common software source code for basic system functionality such as multi-modality image viewing, segmentation, registration,

Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
