#### Indications for Use:
The TinniTech ANMP System comprises two (2) mini compact disks that have been prerecorded with selected relaxation music and other sounds spectrally adapted to suit the particular patient's hearing thresholds. The device is indicated to mask and intermittently mask tinnitus as part of a tinnitus management program. The addition of the music is to aid the promotion of relaxation during the tinnitus masking process.
The spectral adaptation of the sound is determined by the patient's audiogram measured by a qualified audiologist; the patient's tinnitus therapy is managed by an appropriate healthcare professional. The target population for the device is adults (18 years of age and over) who present with tinnitus that may or may not be accompanied with hearing loss at the higher frequencies.
#### Intended use
The ANMP System is intended to completely mask and intermittently mask tinnitus as part of a tinnitus management program. The addition of the music is to aid the promotion of relaxation during the tinnitus masking process. The initial hearing and tinnitus tests are conducted by a qualified audiologist familiar with the treatment of tinnitus: the subsequent management of the treatment is carried out by an appropriate healthcare professional.
#### Target population
The target population for the device is adults (18 years and over) who present with tinnitus that may or may not be accompanied with hearing loss at the higher frequencies and who are participating in a tinnitus management program.
#### Device description
The TinniTech ANMP system consists of:
One CD pre-recorded in the MP3 format with selected relaxation music and superimposed low amplitude, wide spectrum noise that is spectrally adapted to compensate for the individual patient's higher frequencies hearing loss. This CD is intended for the complete masking of tinnitus.
One CD pre-recorded in the MP3 format with selected relaxation music that is spectrally adapted to compensate for the individual patient's higher frequencies hearing loss however this CD has been recorded such that the dynamic characteristics of the sound allow the tinnitus to intermittently break through during the quieter passages of the recorded music.
{2}------------------------------------------------
A commercially available, battery powered, stereo, MP3 mini compact disc player with earphones with a performance specification that TinniTech has tested and shown to be suitable for the delivery of the ANMP treatment sounds or waveforms. At this time Tinnitech will supply the Phillips eXpanium 401™ MP3 mini compact disc player. Other suitable players will be offered as TinniTech tests and approves them for the ANMP System.
#### Substantial equivalence
TenniTech is claiming substantial equivalence to two devices:
Equivalence is claimed to the Dynamic Tinnitus Mitigation System, DTM-6 manufactured by Petroff Audio Technologies Inc. 510k number; K974501
Equivalence is also claimed to the Custom TCI Instrument manufactured by Siemens Hearing Instruments, 510k number; K011364.
#### K974501
The Dynamic Tinnitus Mitigation System, DTM-6 manufactured by Petroff Audio Technologies Inc. 510k number; K974501 is a four (4) CD set system capable of being played on any commercial CD player with headphones or speakers. CD#1 provides digital tinnitus masking sounds only, CDs #2, #3 and #4 provide digital tinnitus masking sounds plus relaxation messages, alpha rhythms (a gentle musical sound generated on electronic musical instruments), music and/or nature sounds. CDs #2. #3 and #4 add the indication of promoting relaxation during the tinnitus masking process to the indication of providing 'temporary relief of tinnitus symptoms'.
Like the predicate device K974501 the TinniTech ANMP sounds are recorded on mini CDs (in the MP3 format) capable of being played on any one of a number of good quality, portable MP3 mini disc players, the patient using appropriate earphones to listen to the sound recorded on the discs.
The TinniTech ANMP, like CDs #2. #3 and #4 of the predicate device includes on CD1 digital tinnitus masking sounds together with selected musical sounds to promote relaxation during the tinnitus continuous masking process.
#### K011364
The Custom TCI Instrument manufactured by Siemens Hearing Instruments, 510k number: K011364. is a fully digital. low level noise generator. The device is programmable, with selected noise and output levels and is indicated for use in the delivery of tinnitus habituation and tinnitus masking therapies.
The output noise in the Custom TCI Instrument can be custom-tailored to the user's individual requirements.
{3}------------------------------------------------
Like the predicate device, K011364, the TinniTech ANMP custom-tailors the sounds on both CD 1 and CD 2 to suit the individual patients' hearing requirements. This is achieved analysing the patient's audiogram and boosting the amplitude of those sounds or tones where the patient has been shown to have a reduced hearing threshold.
The TinniTech ANMP also includes on CD 2 specially selected music with a dynamic characteristic that allows the patient's tinnitus sound to intermittently break through the masking effect of the music. This function, like the predicate device K011364, assists in enhancing the patient's habituation to the tinnitus sound.

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.
