#### Device Description:
The Dynamic Coronary Roadmap is a software medical device intended to provide a real-time and dynamic angiographic roadmap of coronary arteries. The angiographic roadmap is automatically generated from previously acquired diagnostic coronary angiograms during the same procedure.
Dynamic Coronary Roadmap uses coronary angiograms, acquired during a PCI procedure, to automatically generate a dynamic angiographic roadmap of the coronary vasculature. This roadmap is then overlaid on the live fluoroscopy images during device navigation. Dynamic Coronary Roadmap works in combination with a Philips interventional X-ray system. The user interface of Dynamic Coronary Roadmap guides the physician through the workflow and minimal additional user interaction from the tableside is required. The following design features support the physician with this:
- Dynamic angiographic roadmap creation; this technique allows the ● physician to automatically construct a 2D dynamic angiographic roadmap of the coronary vasculature from a diagnostic coronary angiogram.
- Live guidance; this technique provides continuous overlay of the dynamic . angiographic roadmap on live fluoroscopic images.
- . X-ray system integration; this provides the physician with a seamless integration with the Philips interventional X-ray system. The clinical product supports:
- o Automatic power ON or OFF; this allows the software medical device to always be available by automatically powering ON and OFF with the X-ray system.
- o 3D Automatic Position Control (APC); this allows the C-arm to automatically move to a nearby available dynamic angiographic roadmap to be able to reuse this for live guidance.
- o Table-side control; this provides the physician with an efficient workflow during interventional procedures. The most frequently used functions that require additional user interaction next to the normal x-ray system interaction can be controlled from the tableside of the Xray system.
#### Indications for Use:
Dynamic Coronary Roadmap, provided as accessory to the Philips Interventional X-ray system, has the following indications for use:
> Dynamic Coronary Roadmap is intended to assist the physician during percutaneous coronary interventions in correlating the device position to the coronary vasculature, by providing a motion compensated overlay of this coronary vasculature.
Dynamic Coronary Roadmap is suitable for use with the entire adult human population.
Dynamic Coronary Roadmap is a software medical device and does not come in contact with a human subject.
{5}------------------------------------------------
The indications for use of Dynamic Coronary Roadmap are similar to the currently marketed and predicate device 3D Roadmap Rel. 1.
Both devices provide image overlay of the anatomic region of interest to assist in visualizing device positioning in the vasculature during fluoroscopic procedures. The difference between the medical devices lies in the nature of the 2D/3D image input data used in combination with the live fluoroscopy. For the physician the difference does not affect the clinical procedure because at any given moment a live fluoroscopic image is displayed on a 2D view of the vasculature. Both devices have the same intended use: they are accessories to the currently marketed Philips interventional X-ray systems and provide real time image guidance.
Based on the information provided above, Dynamic Coronary Roadmap is substantially equivalent to the predicate device 3D Roadmap Rel. 1 in terms of Indications for Use.
#### Technological Characteristics:
Dynamic Coronary Roadmap employs comparable technology as implemented in the predicate device, 3D Roadmap Rel. 1:
- Both tools use an enhanced roadmap on the guidance monitor ● overlaying a roadmap fused with live fluoroscopic images,
- Both tools use pre-acquired angiography data as input for the overlay, and
- Both tools use X-ray system geometry information to match the data (position, scaling).
The technological differences between Dynamic Coronary Roadmap and the 3D Roadmap Rel. 1 are noted below:
- In Dynamic Coronary Roadmap the (enhanced) coronary roadmap is . constructed from a 2D diagnostic coronary angiogram instead of a 3D volume created from a rotational angiogram;
- . In Dynamic Coronary Roadmap the (enhanced) coronary roadmap selects the right roadmap image from the cardiac cycle and positions it based upon the catheter tip.
- Dynamic Coronary Roadmap overlays dynamic structures and compensates for cardiac motion while the predicate 3D Roadmap Rel. 1 overlays static structures provides motion compensation for patient movement.
The differences between Dynamic Coronary Roadmap and the predicate device do not raise any new questions regarding safety and effectiveness. Based on the information provided above, Dynamic Coronary Roadmap is substantially equivalent to the predicate device 3D Roadmap Rel. 1 in terms of technological characteristics.

The following software verification and validation activities have been performed for Dynamic Coronary Roadmap (DCR):
- General verification testing: software verification has been performed ● to cover the system level requirements of the System Requirements Specification as well as the identified risk control measures from the Detailed Risk Management Matrix and the Privacy and Security requirements. These protocols address functional and non-functional aspects of DCR such as reliability, performance and interoperability.
- Algorithm verification testing: Dedicated algorithm verification testing has been performed with standard angiographic and fluoroscopy x-ray data to ensure sufficient functioning of the algorithms. An indirect registration verification was performed focusing only on the registration of the catheter tip and the guide wire.
General Validation Results
Non-clinical software validation testing provided evidence for the intended use, user needs and claims:
> a) Usability validation: Was performed with representative intended users in a simulated environment.
{7}------------------------------------------------
b) Expert opinion Validation: The expert opinion validation was performed in a simulated environment with certified interventional cardiologists. Standard angiographic and fluoroscopy x-ray data was used to allow the expert to evaluate a wide range of variance e.g. region to treat, detector format, patient, acquisition angles.
c) In-house simulated Validation: Validation protocols were created to address each clinical user need in the form of a device navigation workflow. Additional protocols were created to ensure that the Instructions for Use is written on the correct detail level as well as the verification of the effectiveness of the safety mitigations. The protocols were executed in a simulated clinical setting. The validation protocols have been performed by experienced Clinical Marketing Specialists with clinical knowledge gained from work experience and hospital visits. All test participants have experience in the relevant clinical area and therefore are considered equivalent to the intended operator profiles as defined in the Intended use.
#### Summary of Clinical Performance Data:
Dynamic Coronary Roadmap did not require clinical trials to establish substantial equivalence to the predicate device 3D Roadmap Rel. 1. Substantial equivalence was demonstrated with the following attributes:
- Indication for use;
- Technological characteristics;
- Non-clinical performance testing, ●
- Safety and effectiveness. ●
Verification and validation tests as described above were performed on the proposed Dynamic Coronary Roadmap according to the following FDArecognized consensus standards and FDA guidance documents:
- IEC 62304 Medical device software – Software life cycle processes (Edition 1.1, 2015-06). FDA/CDRH recognition number 13-79,

- . Guidance for Industry and FDA Staff - Applying Human Factors and Usability Engineering to Medical Devices, February 3, 2016 (document number 1757).
- . Guidance for Industry and FDA Staff – Content of Premarket Submissions for Management of Cybersecurity in Medical Devices
Conclusion: The verification and validation test results of the Dynamic Coronary Roadmap, comprising of verification testing, usability validation, validation of the user needs and specific claims, and expert opinion validation are passed and support the safety and effectiveness of the product. It conforms to the intended use, the user needs and the claims and is therefore
{8}------------------------------------------------
considered substantially equivalent to the currently marketed device 3D Roadmap Tel. 1.
#### Substantial Equivalence Conclusion:
Dynamic Coronary Roadmap is substantially equivalent to the currently marketed 3D Roadmap Rel. 1 in terms of indications for use, technological characteristics and safety and effectiveness.
Additionally, substantial equivalence was demonstrated by non-clinical performance tests provided in this 510(k) premarket notification.

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.
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.
