## DEVICE DESCRIPTION:
The current standard procedure in the catheterization laboratory (cath lab) for utilizing x-ray and IVUS image streams calls for referencing the native x-ray, IVUS and FFR/iFR imaging and displayed value streams of the patient's vasculature separately on different displays or monitor. This configuration requires the physician, usually an interventional cardiologist, to estimate an identical location on the patient's vasculature location on both the x-ray, IVUS image streams, and FFR/iFR displayed value streams visually on adjacent windows on the same display.
The SyncVision System (System) is displayed on a monitor that is situated next to the native xray, IVUS and FFR/iFR imaging and displayed value streams either in the cath lab or in the control room. The System provides a means to view the angiographic, IVUS, and FFR/IFR values on a single display and automates the manual registration processes performed by the physician.
The objective of the SyncVision System is to optimize and facilitate trans-catheter cardiovascular interventions by means of automated on-line image processing. The current focus of the SyncVision System is on trans-catheter diagnostic and therapeutic interventions performed on the heart and the blood vessels directly connected to it.
The SyncVision System's core component is an image acquisition and processing workstation situated in the coronary catheterization control room. The System also includes additional components such as a procedure room joystick, control room monitor, keyboard and mouse, medical grade isolation transformer along with site-specific cables and video equipment. Cables also connect the workstation to an existing output monitor (not supplied with the System) situated in the procedure room and provide the user in the procedure room with the visual output of the System side-by-side to the existing displays.
The SyncVision System intends to capture the fluoroscopic image stream on line and perform the following functions for the purpose of assisting the interventional cardiologist in visualizing and quantitating the information resulting from images produced by the existing imaging modalities:
- During lesion evaluation: Angiogram selection, quantitative coronary measurements (lesion diameters, length, and stenosis percentage), vessel region enhancement and vessel region stabilization are performed instantly and on line.
- During device positioning, deployment and post-deployment: An on-line image stream, that is enhanced and stabilized, is displayed side-by-side with the existing fluoroscopic image stream.
- . Import and display of IVUS images, leading to a joint display of images acquired by X-Ray and IVUS images corresponding to same selected luminal locations or segments (also known as IVUS Co-registration).
- Import and display of Physiological values, leading to a joint display of images acquired by X-Ray and Physiological values corresponding to same selected luminal locations or segments (also known as Physiological Co-registration).
The Co-Registration is an automation of a manual workflow process used by interventional cardiologists today. The manual procedure in the cath lab for utilizing x-ray and IVUS image
{5}------------------------------------------------
streams calls for referencing the native x-ray and IVUS image streams of the patient's vasculature separately on different displays. This configuration requires the cardiologist to estimate an identical location on the patient's vasculature on the two native image streams (xray and IVUS) on two separate displays. The SyncVision System automates this process by providing an option to display an identical anatomical location on both the x-ray and IVUS image streams automatically on adjacent windows on the same display.
# INDICATIONS FOR USE:
The SyncVision System is an image acquisition and processing system. It is indicated for use as follows:
- To provide quantitative information regarding the calculated dimensions of arterial segments.
- To enhance visualization of the stent deployment region.
- To be used in-procedure in the catheterization lab and off-line for post-procedural analysis.
- To obtain a co-registration of an angiographic x-ray image and IVUS images.
- To obtain a co-registration of an angiographic x-ray image and intravascular blood pressure values.
The primary modifications are to software of the SyncVision Software to enhance the Physiology Co-Registration capability, which correlates between physiological values obtained from Volcano's pressure wire pullback (both iFR and FFR calculations) and their respective locations on a selected angiographic image. There are also administrative, infrastructure, and service modifications. The primary modifications of the new device compared to the predicate device are provided in the Modification Comparison table below.

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.
