Indications for Use
The neoBLUE compact LED Phototherapy System is intended for the treatment of neonatal hyperbilirubinemia. The light can be used for infants in a bassinet, incubator, open bed, or radiant warmer.
Device Story
The neoBLUE compact LED Phototherapy System is a portable phototherapy device for treating neonatal hyperbilirubinemia. It uses high-intensity blue LEDs to deliver light in the 450-470 nm range, which is absorbed by bilirubin. The device consists of a lightweight plastic enclosure that can be used independently on an incubator or mounted to an arm and roll stand for use with bassinets, incubators, or radiant warmers. It includes a treatment timer for patient tracking, a device timer for LED usage, and a white LED exam light. Operated by healthcare professionals in clinical settings, the device provides two intensity settings (high/low). The output is overhead phototherapy; the light intensity and wavelength are designed to treat jaundice while minimizing UV/IR exposure. The device helps reduce bilirubin levels in neonates, facilitating clinical management of hyperbilirubinemia.
Clinical Evidence
No clinical data. Substantial equivalence is supported by bench testing, including electrical safety (IEC 60601-1), electromagnetic compatibility (IEC 60601-1-2), and particular requirements for infant phototherapy equipment (IEC 60601-2-50). Additional testing included software verification, design verification/validation (power, indicators, LED performance, intensity range, effective treatment area, usability), hazard analysis, and human factors validation.
Technological Characteristics

# Substantial Equivalence Discussion
{5}------------------------------------------------
#### Discussion of Differences
Blue and White LEDs
Both predicates and the neoBLUE compact LED Phototherapy System use the same fundamental technology; blue light LED phototherapy for neonates. Blue LEDs emit light in the range of 400 – 550 nm (peak wavelength 450-470 nm). This range corresponds to the spectral absorption of
{6}------------------------------------------------
light by bilirubin. The secondary predicate, K083179 and the neoBLUE compact both contain white LEDs for use as an exam light.
Blue and white LEDs do not emit significant energy in the ultraviolet (UV) region of the spectrum, so there is no UV exposure to the infant; nor do they emit significant energy in the infrared (IR) region of the spectrum. minimizing concern about excessive warming of the infant
All three devices utilize LEDs as the light source. The MediLEDmini uses only blue LEDs during phototherapy treatment, whereas the MediLED and the neoBLUE compact LED Phototherapy System both use blue mixed with white LEDs. The design of the neoBLUE compact LED Phototherapy System incorporates the white LEDs to soften the visual impact of blue light, and for use as an optional exam light before or after phototherapy. As white LEDs also emit blue light, all blue light intensity is included in the total blue light intensity measurement. Therefore, the difference in the LEDs does not raise any new questions of safety or effectiveness.
#### Intensity Settings
The neoBLUE compact LED Phototherapy System compact has two intensity settings, high and low. The predicate devices have one or three settings (high, medium and low). The difference in the intensity settings (1 versus 2 versus 3) does not raise any new questions of safety or effectiveness.
#### Treatment Area
The treatment area for the neoBLUE compact LED Phototherapy System is between the range of the treatment area of the predicates, slightly larger than the MediLEDmini and slightly smaller than the MediLED: 660 cm² @ 40 cm height for the MediLEDmini; 700 cm² @ 35 cm height for the neoBLUE compact LED Phototherapy System; and 800 cm2 @ 40 cm height for the MediLED. This does not raise any new questions of safety or effectiveness.
The differences between the predicate devices, K103735 and K083179, do not raise any new questions of safety or effectiveness.
## Performance Testing
According to the device features, the testing for the following standards were considered required for the device:
- IEC 60601-1:2005/@2012 and A1:2012 Medical Electrical Equipment Part 1 General . Requirements for Basic Safety and Essential Performance
- . IEC 60601-1-2: Edition 4.0 2014-02: Medical Electrical Equipment – Part 1-2: General Requirements for Basic Safety and Essential Performance - Collateral Standard: Electromagnetic Disturbances – Requirements and Tests
- IEC 60601-2-50:2009; Medical Electrical Equipment Part 2-50: Particular Requirements for the . Basic Safety and Essential Performance of Infant Phototherapy Equipment
In addition to the compliance of voluntary standards, the following performance testing was necessary to make a substantially equivalent decision:
- . Software Verification
{7}------------------------------------------------
- Design Verification and Validation ●
- Device power O
- Electrical safety O
- Indicators O
- O LED performance
- Intensity levels O
- Intensity range O
- о Effective treatment area
- o Usability
- . Hazard Analysis
- Human Factors Validation Testing ●
The compliance to applicable standards as above mentioned indicates that the new device in this submission used the same standards as that of predicate device. The compliance with relevant standards in addition to the software validation, design verification and validation, hazard analysis and human factors validation is adequate for the determination of substantial equivalence.
#### Clinical Tests
Not Applicable
#### Conclusions
The neoBLUE compact LED Phototherapy System has the same intended use and similar technological characteristics as the cleared devices. Moreover, verification and validation tests contained in this submission demonstrate that the difference in the submitted models do not raise new questions of safety and effectiveness as that of cleared device.
In the other words, those engineering differences do not: (1) affect the intended use or (2) alter the fundamental scientific technology of the device. Therefore, we conclude that the neoBLUE compact LED Phototherapy System is substantially equivalent to the MediLEDmini (K103735) and Medix MediLED (K083179).
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.
