#### Description of Devices
### AN-Evo1
Different to the more common air conduction hearing devices, with digital bone conducted hearing aids AN-Evo1 the sound is produced in a small vibrator and transmitted by direct contact to the mastoid. From here the sound is transmitted via the skull to the inner ear and transformed directly into nerve impulses.
The AN-Evo1 is a hearing aid battery powered, programmable, digital, bone conduction hearing aid which can be mounted onto different aid front-models. For mounting, extension tips and aidfronts with different mechanical dimensions (lengths of extension tips, size of aid-fronts) are available. The AN-Evo1 is also available in different colors (black, brown and anthracite). It can be used monaural or binaural. For monaural, the hearing aid has one active temple and one none-active temple (dummy-temple). For binaural, the hearing aid has two active temples.
The AN-Evo1 includes a digital programmable amplifier and a bone vibrator unit, which are connected directly in one housing. The bone vibrator of the device is held against the head and is driven electrically by the amplifier to transmit the amplified sound as vibrations to the underneath bones of the skull. It also has a built in microphone for picking up sound and a built in induction coil for picking up magnetic fields from induction loop systems. For selecting the operating mode, a three position mode switch is used. The positions are O, OFF, T. Telecoil (induction coil) and M. Microphone. A Volume Control wheel is used to adjust the output power of the device.
The AN-Evo1 is programmable via the HIPRO-Programming Box and BHMFit2 Fittingsoftware. The fitting will only be conducted by an audiologist, a hearing aid specialist or ENT.
### contact star evo1
Different to traditional air conduction hearing devices, by using bone conduction hearing aids contact star-evo1 the sound is produced in a broadband miniature vibration receiver and transmitted by direct skin contact to the mastoid, the area of the temple bone behind the ear. From here it is transmitted through the skull to the inner ear, where it is transformed into nerve impulses.
The contact star evo1 is a hearing aid battery powered, programmable, digital, bone conduction hearing aid which can be mounted onto different aid front-models. For mounting, extension tips

The contact mini is programmable via the HIPRO-Programming Box and BHMFit2 programming software. The fitting will only be conducted by an audiologist, a hearing aid specialist or ENT.
#### apollon
The apollon is also a bone conduction hearing aid. Unlike conventional hearing aids which depend upon acoustic coupling through air, the apollon is based on bone conduction technology. Sound is transmitted directly through the bones of the cochlea, bypassing the outer and middle ear.
The apollon consists of a bone vibrator unit, a shirt pocket sized amplifier module and a wire cable for connecting the bone vibrator with the amplifier module. The bone vibrator is a
{3}------------------------------------------------
convenient sized unit that is held against the head and is driven electrically to transmit the amplified sound as vibrations to the underneath bones of the skull.
The amplifier module connects the bone vibrator through the wire cable and usually would be carried in the users pocket. The amplifier module is completely self-contained and is battery powered. It also has a built in microphone for picking up sound and a built in induction coil for picking up magnetic fields from induction loop systems. As an added feature an auxiliary 3.5mm input jack allows the user to connect the apollon directly to TV, MP3 players, portable radios or even telephones without any additional adaptors. For selecting the operating mode, a four position mode switch is used. The positions are O..OFF, T..telecoil (induction coil), MT..microphone & telecoil (induction coil) and M..microphone. A Volume Control is used to adjust the output power of the device.
Also, the possibility of a connection between via the DAI (Direct Audio Input) is available. A red LED (Light Emitting Diode) is used for optical low battery warning.

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.
