Indications for Use
Cleerly LABS is a web-based software application that is intended to be used by trained medical professionals as an interactive tool for viewing and analyzing cardiac computed tomography (CT) data for determining the presence and extent of coronary plaques (i.e. atherosclerosis) and stenosis in patients who underwent Coronary Computed Tomography (CCTA) for evaluation of CAD or suspected CAD. This software post processes CT images obtained using any Computed Tomography (CT) scanner. The software provides tools for the measurement and visualization of coronary arteries. The software is not intended to replace the skill and judgment of a qualified medical practitioner and should only be used by people who have been appropriately trained in the software's functions, capabilities and limitations. Users should be aware that certain views make use of interpolated data. This is data that is created by the software based on the original data set. Interpolated data may give the appearance of healthy tissue in situations where pathology that is near or smaller than the scanning resolution may be present.
Device Story
Web-based post-processing software; analyzes 2D/3D coronary images from CCTA scans. Inputs: DICOM-compliant CT images. Processing: Deep learning identifies high-quality images, segments/labels coronary arteries, and segments lumen/vessel walls; user reviews and manually edits segmentations, adjusts plaque thresholds, and demarcates stenosis, stents, and CTOs. Outputs: Plaque, stenosis, and vessel measurements; interactive CORONARY Report. Used in clinical settings by trained medical professionals. Enhances efficiency of manual tasks; aids in determining treatment paths for CAD. Does not replace physician judgment.

### 4. Device Description
Cleerly LABS is a post-processing web-based software application that enables trained medical professionals to analyze 2D/3D coronary images acquired from Coronary Computed Tomography Angiography (CCTA) scans. The software is a post-processing tool that aids in determining treatment paths for patients suspected of having coronary artery disease (CAD).
Cleerly LABS utilizes machine learning and simple rule-based mathematical calculation components which are performed on the backend of the software. The software applies deep learning methodology to identify high quality images, segment and label coronary arteries, and segment lumen and vessel walls. 2D and 3D images are presented to the user for review and manual editing. This segmentation is designed to improve efficiency for the user, and help shorten tedious, timeconsuming manual tasks.
The user is then able to edit the suggested segmentation as well as adjust plaque thresholds, demarcate stenosis, stents, and chronic total occlusions (CTOs) as well as select dominance and indicate coronary anomalies. Plaque, stenosis, and vessel measurements are output based on the combination of user-editable segmentation and user-placed stenosis, stent, and CTO markers. These outputs are mathematical calculations and are not machine-learning based.
Cleerly LABS provides a visualization of the Cleerly LABS analysis in the CORONARY Report. The CORONARY Report uses data previously acquired from the Cleerly LABS image analysis to generate a visually interactive and comprehensive report that details the atherosclerosis and stenosis findings of the patient. This report is not intended to be the final report (i.e., physician report) used in patient diagnosis and treatment. Cleerly Labs provides the ability to send the text report page of the CORONARY Report to the user's PACS system.
Cleerly LABS software does not perform any functions that could not be accomplished by a trained user with manual tracing methods or other commercially available software. Rather, it represents a more robust semiautomatic software intended to enhance the performance of time-intensive, potentially error-prone, manual tasks, thereby improving efficiency for medical professionals in the assessment of coronary artery disease (CAD).
### 5. Intended Use / Indications for Use
Cleerly Labs is a web-based software application that is intended to be used by trained medical professionals as an interactive tool for viewing and analyzing cardiac computed tomography (CT) data for determining the presence and extent of coronary plaques (i.e. atherosclerosis) and stenosis in patients who underwent Coronary Computed Tomography (CCTA) for evaluation of CAD or suspected CAD. This software post processes CT images obtained using any Computed Tomography (CT) scanner. The software provides tools for the measurement and visualization of coronary arteries.
The software is not intended to replace the skill and judgment of a qualified medical practitioner and should only be used by people who have been appropriately trained in the software's functions, capabilities and limitations. Users should be aware that certain views make use of interpolated data. This is data that is created by the software based on the original data set. Interpolated data may give the appearance of healthy tissue in situations where pathology that is near or smaller than the scanning resolution may be present.

The left side of the word, including the "c" and part of the first "e", is in a gradient of green to teal, with a pixelated effect on the left side of the "c". The rest of the word is in a solid blue color. A small registered trademark symbol is visible to the right of the "y".
### 6. Substantial Equivalence
The subject version of Cleerly LABS has an identical intended use and similar operating principles and technological characteristics as the previously cleared predicate Cleerly LABS v2.0 (K202280) device. The subject device introduces modifications to the product labeling as well as changes to the device's operating principle (i.e., workflow) and minor incremental technological enhancements/changes. The modifications do not introduce any changes to the previously cleared existing algorithms or simple mathematical calculations (Cleerly LABS v2.0 (K202280)) and, consequently, could not significantly affect safety or effectiveness. Software testing demonstrates that the subject device Cleerly LABS continues to be safe and effective for its intended use and substantially equivalent to the predicate device Cleerly LABS v2.0.
In addition, the core functions of Cleerly LABS are supported by artificial intelligence, nonadaptive machine learning algorithms for CCTA processing and analysis. As a result, an administrative change to the product code has been introduced for the subject device.

#### 7. Performance Data
Cleerly LABS has been designed, verified and validated in compliance with 21 CFR, Part 820.30 (Design Controls) requirements. The device has been designed to meet the requirements associated with ISO 14971, 2019-12, Medical Devices – Application of Risk Management to Medical Devices and AAMI TIR 57:2016, Principles for medical device security – Risk management. In addition, Cleerly complies with DICOM (Digital Imaging and Communications in Medicine) - Developed by the American College of Radiology and the National Electrical Manufacturers Association.
Software evaluation activities were performed in accordance with ANSI AAMI IEC 62304:2005/A1:2016, Medical Device Software - Software Life Cycle Processes |Including Amendment 1 (2016)] in multiple pre-production environments using simulated data and in production for release verification. Results of testing re-confirmed that the software requirements fulfilled the pre-defined acceptance criteria. Additionally, regression testing was completed, confirming that changes in technological characteristics did not affect the overall performance or functionality of the device.
Outputs of design control activities and software evaluation demonstrate that the modified device continues to be safe and effective for its intended use and is substantially equivalent and intended for the same clinical application, as the originally cleared device under K202280.
### 8. Clinical Data
No clinical testing was conducted to demonstrate safety or effectiveness as the device's non-clinical testing was sufficient to support the intended use of the device.
{8}------------------------------------------------
Image /page/8/Picture/0 description: The image shows the word "clearly" in a stylized font. The first half of the word is in a gradient of green and blue, with a pixelated effect on the left side. The second half of the word is in a solid blue color. A small registered trademark symbol is located to the right of the word.
### 9. Conclusions
The subject version of Cleerly LABS has the same intended use, indications for use, software algorithm and fundamental technology design as the predicate Cleerly LABS v2.0 (K202280). The modifications to the product labeling as well as changes to the device's operating principle (i.e., workflow) and minor incremental technological enhancements/changes do not raise different questions of safety or efficacy. No changes have been made to machine learning algorithms or simple mathematical equations. Software testing demonstrates that the subject device Cleerly LABS continues to perform as intended; therefore, the subject version of Cleerly LABS is as safe and effective as the predicate Cleerly LABS v2.0 (K202280). Thus, Cleerly Labs v2.0 is substantially equivalent.

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.
