#### Device description: VesselNavigator is a software product (Interventional Tool) intended to assist in the treatment of endovascular diseases during an endovascular intervention procedure. VesselNavigator is intended to be used in combination with a Philips Interventional X-ray system. VesselNavigator can be used during any endovascular intervention and covers all vascular anatomy except coronaries and intracranial vessels.
It provides live 3D image guidance for navigating endovascular devices through intended vascular structures in the body, reusing previously acquired diagnostic 3D images. After registration, the 3D volume can be used as a 3D roadmap for navigation; live 2D fluoroscopic images will be overlaid on the 3D volume. In addition, VesselNavigator provides tools to segment the relevant vasculature in the 3D volume (where the end-user is able to edit the segmentation results), place landmarks for easy recognition of key anatomical points of interests, and store and recall of preferred view angles.
Indications for Use: VesselNavigator provides image guidance by superimposing live fluoroscopic images on a 3D volume of the vessel anatomy to assist in catheter maneuvering and device placement.
> VesselNavigator is intended to assist in the treatment of endovascular diseases during procedures such as (but not limited to) AAA, TAA, carotid stenting, iliac interventions.
The Indications for Use statement for VesselNavigator is not identical to the predicate device; compared to MR-CT Roadmap, VesselNavigator is intended to assist in the treatment of endovascular diseases during procedures. However, this difference does not alter the intended use of the device nor does it affect the safety and effectiveness of the device relative to the predicate. Both the subject and predicate device have the same intended use, by superimposing live fluoroscopic images on a 3D volume of the vessel anatomy and are accessories to the Allura Xper X-ray system (K133292), which is an Interventional X-ray imaging system.
{7}------------------------------------------------
Technological VesselNavigator employs comparable technology as its predicate device MR-CT characteristics: Roadmap:
- Both tools run on a separate interventional tools workstation (Philips ● Interventional Workspot, K121296).
- . Both tools provide basic viewing operations to manipulate image data.
- . Both tools have comparable snapshot functionality.
- Both tools provide an overlay of live 2D fluoroscopy images on a 3D . reconstruction (3D volume) of the vessel tree acquired from a previous MR or CT scan; in this way the 3D volume serves as a roadmap to provide additional information for navigating endovascular devices through vascular structures of the patient.
- Both tools support registration of 3D volume with the x-ray system.
- . Both tools support manual correction of the registration.
- Both tools provide dynamic update to changes of the position of the X-rav equipment; the 3D volume is automatically adjusted to any gantry changes and any lateral or longitudinal table movements.
- Both tools have functionality to store roadmaps.
- . Both tools can be controlled from the tableside.
The technological differences between VesselNavigator and its predicate device MR-CT Roadmap are noted below
- VesselNavigator provides functionality to measure distances. This function ● is identical to the reference device HeartNavigator Release 2.
- . VesselNavigator provides functionality to segment the relevant vasculature in the 3D volume (where the end-user is able to edit the segmentation results), place landmarks for easy recognition of key anatomical points of interests, and store and recall of preferred view angles.
- . VesselNavigator tools to remove the table and segment and remove specific bone structures from the view
As these differences are considered low risk (only providing further support to the clinicians in performing interventions) and the functionalities were verified and validated with equivalent methods, these differences do not raise new questions on safety or effectiveness.
Therefore, the VesselNavigator is substantially equivalent to the currently marketed predicate device MR-CT Roadmap in terms of technological characteristics.
{8}------------------------------------------------
Summary of Nonclinical Performance Data:
Non-clinical performance testing has been performed on VesselNavigator and demonstrates compliance with the following International and FDA-recognized consensus standards and FDA guidance document:
- IEC 62304 Medical device software Software life cycle processes (Ed. 1.0, ● 2006),
- . IEC 62366 Medical devices - Application of usability engineering to medical devices (Ed. 1.0, 2007),
- ISO 14971 Medical devices - Application of risk management to medical devices (Ed. 2.0. 2007).
- . NEMA PS 3.1-3.20 Digital Imaging and Communications in Medicine (DICOM) Set (2011), and
- Guidance for Industry and FDA Staff Guidance for the Content of . Premarket Submissions for Software Contained in Medical Devices" (issued May 11, 2005, document number 337).
Software verification testing has been performed to cover the main system level requirements as well as the identified hazard mitigations. Software validation testing included testing of the vessel segmentation tool, the intended use and commercial claims, and usability testing with representative intended users. All of these tests were used to support substantial equivalence of the subject device.
The test results in this 510(k) premarket notification demonstrate that VesselNavigator:
- complies with the aforementioned international and FDA-recognized consensus standards and FDA guidance document, and
- . meets the acceptance criteria and is adequate for its intended use.
Therefore, VesselNavigator is substantially equivalent to the currently marketed predicate device MR-CT Roadmap in terms of safety and effectiveness.
Summary of Clinical The subject of this premarket submission, VesselNavigator, did not require Performance Data: clinical studies to support substantial equivalence.
Substantial The VesselNavigator software medical device is substantially equivalent to the Equivalence currently marketed predicate device MR-CT Roadmap in terms of design Conclusion: features, fundamental scientific technology, indications for use, and safety and effectiveness. The (non-)clinical performance tests provided in this 510(k) premarket notification demonstrates that the proposed VesselNavigator is as safe and effective as its predicate device without raising any new safety and/or effectiveness concerns.
Two short videos show you everything — or skip straight to the written tutorial if you'd rather read. You can reopen this any time from the Tutorial button in the top bar.
Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
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.
