Indications for Use
The intended use of the CARTO® 3 System is catheter-based cardiac electrophysiological (EP) procedures. The CARTO® 3 System provides information about the electrical activity of the heart and about catheter location during the procedure. The system can be used on patients who are eligible for a conventional electrophysiological procedure. The system has no special contraindications.
Device Story
CARTO 3 EP Navigation System V5.2 is a catheter-based cardiac mapping system. It acquires intracardiac electrical signals and catheter location data using magnetic and Advanced Catheter Location (ACL) technologies. The system includes a new CARTOFINDER Module and workstation that processes multi-connector electrode catheter signals to generate 3D anatomical and electroanatomical maps. Maps include 4D Local Activation Time (LAT), Cycle Length (CL) Unipolar Signal, CL Variation, and Regions of Interest (ROI) for focal and rotational activation patterns. Used in EP labs by physicians to visualize arrhythmia patterns. Output is displayed on a 3D graphical workstation. The system assists in diagnosing cardiac arrhythmias by identifying signal propagation directions. It does not provide therapy; therapeutic decisions rely on all available clinical information. Benefits include enhanced visualization of complex cardiac electrical activity.

The CARTO® 3 EP Navigation System Version 5.2 and Accessories is Device Description: a catheter-based atrial and ventricular mapping system designed to acquire and analyze data points, and use this information to display 3D anatomical and electroanatomical maps of the human heart. The location information needed to create the cardiac maps and the local electrograms are acquired using a specialized mapping catheters and reference devices. The system allows electrograms and cardiac maps display based on the received intracardiac signals from the catheters. The CARTO® 3 System V5.2 uses two distinct types of location technology - magnetic sensor technology and Advanced Catheter Location (ACL) technology.
> The CARTO® 3 EP Navigation System Version 5.2 is a modification to the CARTO® 3 EP Navigation System Version 4.2 to add the CARTOFINDER™ Module and workstation as an accessory to the CARTO® 3 System. The CARTOFINDER™ Module sends recorded electrical signals collected from multi-connector electrode catheters to the CARTOFINDER™ workstation, which generates new visual format maps to be displayed in the CARTO® 3 EP Navigation System. The new visual format maps generated by the CARTOFINDER™ Workstation are divided into two categories:
- 1. Dynamic mapping algorithms: Wherein the physiological scoring is changing over time after inspecting the input signals in a certain window of interest.
- 2. Static mapping algorithms: These maps set a single physiological scoring per electrode, after analyzing the input signals during the full recording time.
The CARTOFINDER™ Workstation creates the following Dynamic and Static Maps:
- 1. 4D LAT: Dynamic map of the Local Activation Time.
- 2. Cycle Length (CL) Unipolar Signal: Static map showing the dominant cycle length measured on each recorded channel per recording/data acquisition set.
- 3. Cycle Length (CL) Variation: Static map showing the standard deviation cycle length measured on each recorded channel.
- 4. CARTOFINDER™ Region of Interest (ROI) Focal: This map will identify the area with OS morphology on the unipolar electrograms that are activated early compared to the
{5}------------------------------------------------
surrounding multi-connector (MC) electrode catheter recorded channels.
- 5. CARTOFINDER™ (ROI) Rotational: This map will identify rotational activation patterns that occupy at least 50% of the cycle length map (this condition requires sufficient spatial and temporal resolution).
CARTO® 3 EP Navigation System Version 5.2 and Accessories consists of the following components:
- Patient Interface Unit (PIU) ●
- 3D graphical Workstation that serves as the Graphic User Interface (GUI), Wide-Screen monitors, keyboard, and mouse
- Intracardiac In Port
- Intracardiac Out Port ●
- Power Supply ●
- . Patches Connection Box and Cables
- Pedals
- Location Pad ●
- CARTOFINDER™ Workstation ●
- Non-Biosense Webster basket catheter interface cable (CA-● 5400-61)
Because CARTOFINDER™ is only available on this version, the CARTO® 3 System V5.2 will be marketed in parallel with the CARTO® 3 System V6.0 software. Future software releases may incorporate this functionality pending company business decisions
- Indications for Use: The intended use of the CARTO® 3 System is catheter-based cardiac electrophysiological (EP) procedures. The CARTO® 3 System provides information about the electrical activity of the heart and about catheter location during the procedure. The system can be used on patients who are eligible for a conventional electrophysiological procedure. The system has no special contraindications.

The CARTO® 3 System V5.2 is substantially equivalent to the CARTO® 3 System V4.2, as the mechanism of the diagnostic maps of both devices remains the same. Both devices use IC annotated signal in a known location and present them in a sequence that determines the propagation direction of the signal in the tissue allowing the physician to diagnose the arrhythmia pattern. Except for the CARTOFINDER™ Workstation, the hardware components of the CARTO® 3 System V5.2
{7}------------------------------------------------
are identical to those described for the predicate CARTO® 3 System V4.2.
The CARTO® 3 EP Navigation System, Version 5.2 underwent Performance Data: extensive bench and pre-clinical testing under simulated clinical conditions to verify the new and modified features and to demonstrate with regression testing that these modifications did not negatively affect existing features. The CARTO® 3 EP Navigation System, Version 5.2 passed all tests in accordance with appropriate test criteria and standards, and the modified device did not raise new questions of safety or effectiveness.
### Bench Testing:
Non-clinical performance testing completed for the CARTO® 3 EP Navigation System, Version 5.2 included:
- CARTO® 3 System Version 5.2 verify the functional . requirements and hardware configurations with the new CARTOFINDER™ Module and Workstation, regression testing of all CARTO® 3 System legacy features, verify system functionality for all supported catheters, and usability testing.
- . CARTOFINDERTM Workstation testing - verify the signal preprocessing and annotation detection, maps and catheter generation and coloring, CARTOFINDER™ functionality (including MC catheter support), stimulation detection and blanking, coloring projection and interpolation, power reject algorithm performance, and usability testing.
- CARTOFINDER™ integration verify that the new module . interface with the CARTOFINDER™ Workstation meets requirements and functions as intended when integrated with the CARTO® 3 system.
- . Interface cable - verification testing was completed for the interface cable connected to a non-Biosense Webster basket catheter with the CARTO® 3 System.
### Animal Testing:
Animal testing was performed to evaluate the CARTO® 3 System Version 5.2 and CARTOFINDER™ Workstation workflow under simulated clinical workflow.
### Clinical Data:

The data also supported the clinical performance of the compatible catheters with the new maps. The information provided by these maps
{8}------------------------------------------------
are for diagnostic purposes only. Therapeutic treatment should rely on all available information in the EP lab.
The CARTO® 3 EP Navigation System, Version 5.2 is substantially Conclusions: equivalent to the currently cleared CARTO® 3 EP Navigation System, Version 4.2 based on the completion of non-clinical bench testing, preclinical testing, and clinical data as well as similar principles of design, operation and indications for use.
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.
