# Device Description
The VERAFEYE Imaging catheter is an 11F sterile, single use device for use in the evaluation and guidance of cardiac structures and other devices used during intracardiac procedures. It comprises a transducer array that is located at the distal end of the device; automatic rotation of the transducer array within the catheter body enables the acquisition of 360° degree images.
Also incorporated in the tip of the device are electro-magnetic sensors that enable the localization of the tip of the device relative to the anatomy of the patient and a radio-opaque marker.
The 95cm working length of the device facilitates access to the cardiac anatomy via the femoral vein. An articulation mechanism within the catheter and associated actuators on the handle of the device enable to operator to deflect the distal portion of the device up to 90° in opposing directions.
K261849
Page 2 of 10
{6}
Connection to the associated VERAFEYE Imaging and Guidance System is achieved via 1m proximal tail of the catheter. The length of the tail enables connection to be made outside of the sterile field.
Provided and packaged with the sterile catheter are two needle guides to assist in the expulsion of air from around the transducer. This is achieved in conjunction with deionized water, that is provided separately as an accessory.
The packaging system comprises a PETG tray that supports the catheter and needle guide. The primary sterile barrier is provided by a Tyvek/Nylon pouch which resides in a cardboard shelf box.
Sterility is achieved via exposure to ethylene oxide.
Packaging contents:
- VERAFEYE Imaging Catheter
- Flushing needle guide (2 units)
LUMA Vision provides the following accessories as part of VERAFEYE Imaging Catheter:
- Catheter flushing liquid (deionized water)
**Intended Use:** Cardiac
**Indications for Use:**
The VERAFEYE Imaging Catheter is intended for intracardiac and intraluminal visualization of cardiac and great vessel anatomy and physiology, as well as visualization of other devices in the heart of adult patients.
The catheter is intended for imaging guidance only and not for treatment delivery during cardiac interventional percutaneous procedures.
**Functional and Technological Comparison**
Table 1 below provides a functional and technological comparison between the VERAFEYE Imaging Catheter Version 2 and the legally marketed predicate device, VERAFEYE Imaging Catheter Version 1 (K242893).
K261849
Page 3 of 10
{7}
The primary difference between the predicate and the subject device is the incorporation of an additional electro-magnetic tracking sensor at the tip of the device. The implementation of the additional sensor enables tracking in 6 degrees of freedom.
Additionally, an acoustic marker placed within the device facilitates co-registration the rotational orientation of the transducer with the catheter body, allowing the VERAFEYE Imaging and Guidance System to generate images with localization data.
As shown in Table 1, the subject device has the same intended use, classification, regulation, product code, imaging modality, and principles of operation as the predicate device. The design changes in Version 2 are limited to incremental enhancements and do not alter the fundamental technology or intended use.
The identified differences do not raise new questions of safety or effectiveness. Substantial equivalence is supported by non-clinical performance testing. No clinical testing was required.

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.
