### Section 5.0 510(k) Summary
Image /page/1/Picture/1 description: The image shows the word "otometrics" in a sans-serif font. Above and to the right of the word is a black abstract shape. The shape appears to be a stylized representation of an ear. The text is in a simple, clean font, making it easily readable.
#### Description of the Device
GN Otometrics Type 1077 AccuScreen is a handheld examination system based on Otoacoustic Emissions (OAE) and/or Auditory Brainstem Response (ABR). Identical techniques are used - among others - on Fischer-Zoth model, Echo-Screen. The Type 1077 AccuScreen is designed to be easy to use, and employs automated OAE and/or ABR tests. The measurement flow is menu-guided and evaluation is based upon signal statistics. The Type 1077 AccuScreen is designed for trained personnel in a medical or home environment to examine hearing in infants from 34 weeks (gestational age) up to 6 months of age that are well enough to be ready for discharge from the hospital.
The Type 1077 AccuScreen OAE system consists of the AccuScreen handheld device, a Docking Station with mains adapter, OAE probe with disposable probe- and ear-tips, and AccuLink software for installation on a PC. When ABR is included an optional ear coupler cable and disposable ear couplers can be included in the system, as well.
The AccuScreen handheld device comes in two hardware versions; one for OAE screening only and one for both OAE and ABR screening. Both versions are based on a common hardware platform (printed circuit board), but with different configurations.
The measurement application is controlled from a self-contained firmware (software) module installed in the handheld device. The firmware module can be configured to allow different OAE measurement types (DPOAE and/or TEOAE) by a license key stored in the device.
For automated OAE measurements, the handheld device uses an OAE probe, designed and manufactured by PATH Medical GmbH. The OAE probe has been granted marketing clearance by the FDA following the submission of a 510(k) (K100661).The OAE probe is fitted with an ear-tip (constructed of biocompatible material) and inserted in the ear canal of the patient. The AccuScreen device plays stimulus sounds in the ear canal via small speakers in the OAE probe. The AccuScreen device measures the patient's response to the stimulus sounds via a microphone in the probe. The measured response is processed by the AccuScreen device using statistics to help determine whether or not a hearing loss may be present.
When the OAE measurement is a DPOAE measurement, the stimulus signal is while and of two pure tone signals, each presented by a speaker in the OAE probe. When the OAE measurement is a TEOAE measurement, the stimulus signal is a series of broadband clicks presented by one speaker in the OAE probe.

### Section 5.0 510(k) Summary
Image /page/2/Picture/1 description: The image shows the word "otometrics" in a sans-serif font. To the right of the word is a black abstract shape that looks like three circles connected together. The word is in lowercase letters and is positioned horizontally. The image is in black and white.
For automated ABR measurements, the device uses the OAE probe, or an ABR ear coupler cable for providing the acoustical stimulus for the patient. When the ABR ear coupler cable is used, its speakers are inserted in the ABR Ear Couplers, which are then placed over the patient's ear with a biocompatible adhesive gel on the ear coupler rim. The stimulus signal is a series of broadband clicks and the AccuScreen device measures the patient's response as an electrical signal from three electrodes placed on the head of the patient. The measured response is processed by the AccuScreen device using statistics to help determine whether or not a hearing loss may be present.
The 1077 Docking Station serves as a means of providing power to charge the rechargeable battery in the AccuScreen handheld device. The Docking Station also provides an interface to an optional label printer or to a PC. The label printer is used for printing test results from the AccuScreen handheld device. The PC is used for transferring patient demographical data to the AccuScreen handheld device and for collecting measurement results from the AccuScreen handheld device by using the AccuLink PC software.
#### Intended Use
AccuScreen is a portable instrument used to screen infants for hearing loss. The instrument uses the Distortion Product Otoacoustic Emissions (DPOAE), Transient Evoked Otoacoustic Emissions (TEOAE) and Auditory Brainstem Response (ABR) technologies. The instrument is intended for screening infants from 34 weeks (gestational age) up to 6 months of age that are well enough to be ready for discharge from the hospital. Infants should be asleep or in a quiet state at the time of screening. AccuScreen is intended for use by audiologists, ENTs and other health care professionals.
#### Comparison to Predicate Device
The system most similar to the Type 1077 AccuScreen in terms of system components, features and measurement principals is the Echo-Screen (Models T, D, TD, TA, DA, TDA) from Fischer-Zoth Audiologic Systems. The Echo-Screen device has been granted marketing clearance by FDA following the submission of a 510(k).
The following table identifies the existing models of the Echo-Screen device and the corresponding models planned for the 1077 Accuscreen. With the exception of the 1077 Accuscreen ABR model for ABR screening only, all other model combinations between the two devices are the same.

The design and working principals of Type 1077 AccuScreen are very similar to the Echo-Screen with the technological improvements added to the design. This similarity is due largely to the fact that the same engineers at Fischer-Zoth Audiologic Systems that designed the Echo-Screen also provided significant input to the design of the 1077 Accuscreen.
Both systems use a battery driven handheld and portable device with attached OAE probe- and ABR electrode cables.
From a measurement perspective, the two devices utilize the same measurement methods (DPOAE, TEOAE and ABR) and use very similar probes and electrodes. The signal processing and detection methods within the devices are also very similar, and both devices give a Pass/Refer result as an automated screening result.
The primary difference between the two devices is in the mechanical design, display technology and graphical user interface. Here the Echo-Screen uses a larger standard off-the-shelf box for housing, a small and low resolution monochrome display and the off the short of the reading, while the Type 1077 AccuScreen uses a

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.
