#### 5.9 Proposed Device Description
The Comby EEG Cap is an electrode positioning system used to quickly place the standard 20 EEG electrodes or more in a uniform and consistent manner on the head and body in order to transmit electrophysiological signals from an individual to data collection devices. The Comby EEG Cap is made from high quality profile rubber net, electrode plastic holders made of SEBS and electrodes. Electrodes is made of two different conductors, sintered Ag/AgCl and gold coated plates. The EEG Comby Cap is fixed by Velcro tape holders which are fastened beneath the chin of the tested person. The cap holders is fixed to a belt, placed beneath the arms and around the chest of the tested person. The high quality profile rubber net holds the electrodes securely in position during the EEG recording. Wires are attached to each electrode and exit the cap to form a cable, which is used to connect the cap to the EEG equipment, either through an adapter cable, or directly to the equipment with the 25-pin D-sub connector. The electrical activity of the brain is transferred through the conductive Electro-Gel/paste to the recessed electrode and then to the EEG or computer equipment for evaluation. The electrodes on the standard caps are positioned in
{5}------------------------------------------------
accordance with the International 10-20 System of electrode placement. In addition, the Comby EEG Cap with as few as 2 to as many as 64 electrodes. Comby EEG are also produced based on customer specified electrode placements, with electrodes made of Ag/AgC1 material. Customized wiring and connectors offer additional options.
The Electro-Gel is used with external electrodes as the conductor between the scalp and the
(recessed) electrodes. It also reduces impedance (resistance to alternating current) between the
electrode surface and the skin "Electroconductive gel is a legally marketed product in US -

{6}------------------------------------------------
Styrene-ethylene-butylene-styrene, also known as SEBS, is an important thermoplastic elastomer (TPE) which behaves like rubber without undergoing vulcanization. Mounts made of SEBS provide an effective hold of the electrodes in the position without producing any pressure around the muscles. Muscle pressure artifacts are very common in EEG recording, and should be minimized to achieve the best recording result. SEBS electrode mounts are also more comfortable for the patient.
Comby EEG Caps have shorter cables when compared to the predicates. Shorter cables create less artifacts during the recoding form the environment. it is used on purpose to get better results as the recording can be made closer to patient without any environmental disturbance.
In COMBY EEEG CAP, maximum of 64 electrodes are required to provide coverage for the complete scalp.
The stated differences are made in the purpose of improving the EEG recording quality and patient comfort. Therefore COMBY EEG cap performs minimally as well or better that the predicates.
All the differences do not affect the safety and effectiveness of the subject device which is concluded after all the required testing, so there are no safety and effectiveness issues relating to the subject system.
Clinical testing is not required

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?

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.
