#### Subject device description
The NEBA® Compact EEG2R Mobile Headset is a battery powered (3.7v Lithium-lon battery wirelessly charged using a Qi-compliant receiver) wireless (Bluetooth LE) EEG headset which facilitates the placement of EEG electrodes. The NEBA® Compact EEG2R Mobile Headset (CEG2R) has both hardware and software components. Hardware comprises an EEG electrode system that serves to conduct EEG potentials from the human scalp for transfer to a built-in wireless EEG amplifier. The software provides EEG amplifier hardware control, recording, storage, and user interfaces for waveform monitoring, patient information entry and storage, and accessing stored EEG data.
The CEEG2R Headset has two primary purposes:
- . To aid in EEG electrode positioning on the head such that electrodes are positioned in intended locations accurately and reliably per the standard 10-20 International Electrode Placement System. The default leads configuration includes CZ, left ocular (OC-L), right ocular (OC-R), left ear (E-L), right ear (E-R), and Ground (GND) positions;
- . To transmit electrophysiological signals from positioned electrodes to an EEG recording and monitoring device via an internal EEG amplifier with wireless transfer communication.
The CEEG2R Headset is constructed using biocompatible patient contact surfaces, the major components formed of polyurethane and polyester. The headset is held in place using a flexible platform at the top of the head and adjustable arms that terminate at lateral supports at the sides of the head.
The headset is designed for use with accessory disposable silver/silver-chloride (Ag/AgCl) electrodes (K781430).
An integral, counter posing pressure tab accepts a disposable electrode for placement at the top medial portion of the head (at location CZ of the 10-20 International Electrode Placement System). Connection components facilitate the quick insertion and removal of the electrodes and flexible leads. Electrodes for use on the scalp and hair bearing scalp region use a low-viscosity integrated wet-gel conductive medium embedded in the electrodes along with integrated low-tack adhesive optimized for hair compatibility and system stability.
The system is stabilized on the head through use of low tack adhesive-lined electrodes, conformable lateral support linings, spring hinges, and a flexible headband platform.
The system interfaces with the CEG2R recording and monitoring software for signal acquisition, signal measurement, and electrode impedance measurement by way of a built-in wireless amplifier. The battery, wireless battery charger, wireless communication transmitter and amplifier printed circuit board (PCB) are located atop a midline-located headband platform of the headset.
#### Subject device Intended Use
The NEBA® Compact EEG 2R Mobile Headset) is intended to capture, amplify, and wirelessly transmit electrical brain activity for review by a trained medical professional using the CEEG2R recording software. The NEBA Headset comprises an electrode positioning system for placing single-use disposable electrodes on the head (Vermed® A10005, ANSI/AAMI EC12 compliant silver/silver-chloride
{5}------------------------------------------------
(Ag/AgCl) electrodes cleared in K781430). Contained within the headset is a wireless EEG amplifier module. The NEBA Headset and its associated software do not provide any diagnostic conclusion or automated alerts of any clinical event about a patient's condition. The NEBA Headset transmits electrophysiological signals from the electrodes to a CEEG 2R IEC/UL 60950-1 safety compliant computer running the NEBA CEEG 2R recording software. The system supports six electrode locations (CZ, left ocular, right ocular, left ear, right ear, and ground) on four flat flexible leads and one plastic tab (the latter to support the CZ electrode). The CEEG2 Headset is intended for use in clinical settings in individuals six years of age and older. (Rx only).
### Comparison of predicate devices to subject device
The NEBA® Compact EEG2R Mobile Headset (CEEG2R) is substantially equivalent to the REMI device when combined with the Nihon Kohden AE-120A EEG headset. NEBA shares the same technological characteristics as the predicate devices, but there are some differences. Both battery-powered predicates are reduced montage EEG devices that wirelessly transmit EEG data to an accessory device running software.
The primary predicate is the REMI device. The NEBA® Compact EEG2R Mobile Headset (CEG2R) is designed to amplify, capture, and wirelessly transmit EEG data from the CZ channel to an accessory software intended for monitoring and reviewing EEG data. Similarly, the REM device is called out as the primary predicate as it is intended to wirelessly transmit a single channel of electrical activity for subsequent review. Both are intended for professional prescription use only and for patients 6 years and older.
Neither the REMI device nor the NEBA® Compact EEG2R Mobile Headset are indicated for making any diagnosis or diagnostic recommendations and both are intended only to facilitate the monitoring and review of physiological signals.
The secondary predicate, the Nihon Kohden AE-120A, is called out to achieve the NEBA® Compact EEG2R Mobile Headset positionality. Both the Nihon Kohden AE-120A and the NEBA® Compact EEG2R Mobile Headset use mechanical headsets to aid in EEG electrode positioning to approximate the 10-20 International Electrode Placement System.
The predicate systems and the NEBA® Compact EEG2R Mobile Headset were evaluated for safety and effectiveness in quality systems per FDA guidance and using compliance standards. The predicate systems and the NEBA® Compact EEG2R Mobile Headset were evaluated according to ISO 10993-1 biological evaluation and associated FDA guidance.
Given the discussion above and the substantial equivalence table below, NEBA Health asserts that the differences between the NEBA® Compact EEG2R Mobile Headset and the predicate devices do not raise different questions of safety and effectiveness based on the performance testing used to address the technological characteristics.
NEBA Health asserts the NEBA Health device (CEEG2R) is substantially equivalent to the combined predicate devices.

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.
