Indications for Use
The Type 1077 device is indicated for use in the recording and automated analysis of human physiological data (screening auditory brainstem responses and/or otoacoustic emissions) necessary for the diagnosis of auditory and hearing-related disorders. Distortion Product Otoacoustic Emissions and Transient Evoked Otoacoustic Emissions: The Type 1077 DPOAE module and TEOAE module can be used for patients of all ages, from children to adults, including infants and geriatric patients. It is especially indicated for use in testing individuals for whom behavioral audiometric results are deemed unreliable, such as infants, young children, and cognitively impaired adults. Auditory Brainstem Response: The Type 1077 ABR module is especially intended for infants from 34 weeks (gestational age) up to 6 months of age. When the device is used to screen infants. they should be asleep or in a quiet state at the time of screening. The device is intended for use by audiologists. ENT's and other healthcare professionals..
Device Story
Handheld, battery-operated screening device for auditory function; utilizes OAE probe (PATH Medical GmbH) with ear-tip inserted into patient ear canal. Device plays stimulus sounds (broadband clicks for TEOAE; two pure tones for DPOAE) via probe speakers; records patient response via probe microphone. Firmware processes signals using statistical analysis to determine presence of hearing loss. Used by audiologists, ENTs, and healthcare professionals in clinical settings. Output displayed on touch screen; assists clinicians in identifying potential hearing disorders in patients unable to provide reliable behavioral responses. Benefits include objective, automated screening for infants and cognitively impaired populations.
Clinical Evidence
Clinical study compared Type 1077 to predicate Echo-Screen (K013977) across 130 ears in various age groups (6mo-9y to >59y). Primary endpoints were DPOAE and TEOAE agreement. Overall agreement was 93.8% for DPOAE and 91.5% for TEOAE. Discrepant results in older cohorts were adjudicated using a diagnostic OAE device, confirming the subject device's accuracy.
Technological Characteristics
Handheld, battery-operated (3.7V/1800mAh Li-ion). Features 3.5-inch color TFT touch screen. Uses OAE probe with biocompatible ear-tips. Connectivity via IR to docking station with USB interface. Safety standards: EN 60601-1, IEC 60601-2-26, IEC 60601-2-40. Biocompatibility per ISO 10993-5, -10, -1, -12. Software-controlled via internal firmware module.
Indications for Use
Indicated for screening auditory brainstem responses (ABR) and/or otoacoustic emissions (OAE) in humans. DPOAE/TEOAE modules: all ages, including infants, children, adults, and geriatric patients; specifically for those with unreliable behavioral audiometric results (e.g., cognitively impaired). ABR module: infants 34 weeks gestational age to 6 months. Contraindications: infants must be asleep or in a quiet state.

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
{1}------------------------------------------------
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 deter or not a hearing loss may be present.
When the OAE measurement is a DPOAE measurement, the stimulus signal is composed of two pure tone signals, each presented by a speaker in the OAE measurement is a TEOAE measurement, the stimulus signal is a series of broadband clicks presented by one speaker in the OAE probe.
While the device has not changed from our 2012 510(k) submission K122067, the target population has been expanded as described in the indications statement directly below:

Summary of non-clinical testing: (Performed in K122067): Standards testing demonstrated compliance with the safety standards in the table above, as well as:
ISO 10993-5 Biological Evaluation of Medical Devices: Tests for Cytotoxicity
ISO 10993-10 Biological Evaluation f Medical Devices: Tests for Irritation and delayed-type hypersensitivity ISO 10993-1 Biological Evaluation of Medical Devices: Evaluation and Testing
ISO 10993-12 Biological Evaluation of Medical Devices: Sample Preparation and Reference Materials
Bench testing also demonstrated compliance with system hardware and software specifications. A revised risk analysis was also conducted.
Summary of clinical testing: Clinical testing was performed to confirm that the Type 1077 can produce valid results in patients of all age groups and performed in a comparable manner to the predicate Echo-Screen, Fischer-Zoth Audiologic Systems K013977. Subjects were tested on Type 1077 and again on the Echo-Screen. The goal was to test and compare a minimum of 16 ears per age group. Overall 130 ears were tested and compared, with overall DPOAE agreement of 93.8% and TEOAE agreement of 91.5%. The results are shown below.
| Age | 6 mo-9 y | 10-19 y | 20-39 y | 40-59 y | >59 y | Total |
|-------------------------------|--------------------|--------------------|--------------------|-------------------|-------------------|---------------------|
| Number of ears<br>recommended | 20 | 20 | 20 | 20 | 20 | 100 |
| Achieved/tested | 26 | 22 | 30 | 36 | 16 | 130 |
| DPOAE<br>agreement | 26/26<br>(100.0 %) | 22/22<br>(100.0 %) | 30/30<br>(100.0 %) | 33/36<br>(91.7 %) | 11/16<br>(68.8 %) | 122/130<br>(93.8 %) |
| TEOAE<br>agreement | 26/26<br>(100.0 %) | 22/22<br>(100.0 %) | 30/30<br>(100.0 %) | 30/36<br>(83.3 %) | 11/16<br>(68.8 %) | 119/130<br>(91.5 %) |
After identifying that there were some discrepant results between our device and the predicate device. (40-59 y & >59 y age groups) we used a diagnostic OAE device to re-test all test subjects for which there was not a match between the Type 1077 and predicate device. Our intent was to determine which of the two devices (Type 1077 or Predicate) provided the correct result. After performing the diagnostic OAE testing, we discovered that the predicate device was found to have provided incorrect results in 11 of the 19 cases. Overall the results showed that the Type 1077 performed in a comparable manner to the Echo-Screen on the expanded patient population shown in the revised indications for use.
Conclusion: After analyzing bench testing, safety, EMC, software, and clinical validation testing we conclude that the MADSEN AccuScreen Type 1077 (with expanded indications for use) is as safe and effective as the predicate device, and has essentially the same technological characteristics, thus rendering it substantially equivalent to the 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.

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.
