Indications for Use
Meniett 20 is indicated for symptomatic treatment of Menière's disease. The therapeutic effect of Meniett 20 is achieved by applying low frequency, low amplitude pressure pulses to the middle ear whereby inner ear endolymphatic fluids are assumed to be evacuated from the cochlea and thus relieve the patient of the symptoms associated with endolymphatic hydrops.
Device Story
Meniett 20 is an electronically controlled membrane pump used for home-based symptomatic treatment of Menière's disease. Following surgical myringotomy and placement of a ventilation tube, patients self-administer therapy by placing an ear-cuff in the external ear canal. The device generates low-frequency, low-amplitude pressure pulses (10-16 mbar) delivered to the middle ear to evacuate endolymphatic fluids from the cochlea. Treatment typically involves three daily sessions of three minutes each. The device features a pump house, electronic hardware, software, and an ear-cuff interface. A pulse shape selector allows switching between three pulse patterns. Indicators on the front panel facilitate patient communication. The device is intended to relieve vertigo attacks and improve balance/functionality. Clinical benefit is demonstrated by symptom relief during active disease periods.
Clinical Evidence
Clinical study of 20 patients with definite Meniere's disease and active vestibular symptoms. Patients treated with daily middle ear pressure pulses for 4 weeks, with many continuing up to 4 months. Primary endpoints: relief of vertigo attacks and improvement in balance/functionality. Results: 18 of 20 patients achieved intended clinical effect; no adverse effects observed. Temporary symptom relapses occurred in patients who discontinued use, with relief returning upon treatment resumption.
Technological Characteristics
Electronically controlled membrane pump; plastic encapsulation; battery-powered. Delivers low-frequency, low-amplitude pressure pulses (10-16 mbar) via ear-cuff. Includes pulse shape selector (3 settings), on/off button, and status indicators. Operates as a standalone unit for patient self-use.
Indications for Use
Indicated for symptomatic treatment of Menière's disease in patients with active vestibular symptoms. Requires prior surgical placement of a ventilation tube in the eardrum.
Regulatory Classification
Identification
An auditory impedance tester is a device that is intended to change the air pressure in the external auditory canal and measure and graph the mobility characteristics of the tympanic membrane to evaluate the functional condition of the middle ear. The device is used to determine abnormalities in the mobility of the tympanic membrane due to stiffness, flaccidity, or the presence of fluid in the middle ear cavity. The device is also used to measure the acoustic reflex threshold from contractions of the stapedial muscle, to monitor healing of tympanic membrane grafts or stapedectomies, or to monitor followup treatment for inflammation of the middle ear.
Special Controls
*Classification.* Class II (special controls). The device, when it is a tympanometer or auditory impedance tester that complies with FDA-recognized consensus standard ANSI S3.39, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 874.9.

This medical device is being submitted in this 510(K) Notification by virtue of the fact that it is substantially equivalent to hypo / hyperbaric pressure chambers which have been used previously for the treatment and temporary relief of symptoms associated with Meniere's Disease. The Meniett 20 is a device which functions in a range of performance specifications which are similar to a conventional tympanometer and is used in a manner similar to a hypo / hyper baric pressure chamber to create localized overpressure in the middle ear to relieve the symptoms associated with Meniere's Disease.
# Device Description:
Meniett 20 is indicated for symptomatic treatment of Menière's Disease. The therapeutic effect of Meniett 20 is achieved by applying low frequency, low amplitude pressure pulses to the middle ear whereby inner ear endolymphatic fluids are assumed to be evacuated from the cochlea and thus relieve the patient of the symptoms associated with endolymphatic hydrops.

Patient treatment
The treatment consists of two phases:
- 1. Myrongotomiy
A surgical intervention whereby a conventional ventilation tube is surgically placed in the eardrum of the ear to be treated. This intervention is performed in exactly the same way and using the same materials as for other indications, e.g. otitis media.
- 2. Application of pressure pulses to the middle ear
The therapy starts after the ventilation tube has been placed in the eardrum. The patient is instructed in how to place the ear-cuff in the external ear canal to minimize leakage to the outer environment. The patient is instructed to treat him/herself three times daily, morning, midday and evening and for three minutes each time. The total daily exposure of pressure pulses in the range of 10-16 mbar with this dosage is 64.8 seconds. Alteration of the standard dosage may be done in after consultation with the treating doctor.
The treatment is continued for as long as the patient finds him/herself in a period of attacks of vertigo. During periods of remission there is no need for treatment
Meniett 20 is an electronically controlled membrane pump. Meniett 20 generates dynamic pressure and consists of a pump house, electronic hardware, software and encapsulation. In connection with the pump house there is a tube to which an ear cuff is connected and through which air pressure pulses from Meniett 20 are transferred to the patient's ear canal. The construction is encapsulated in a plastic cover designed specially for Meniett 20. There is an opening for replacing the battery. With the help of a pulse shape selector, concealed in the battery compartment, there is a possibility to switch between three different pulse shapes. To start and stop the treatment there is an on/off button on the front panel. On the front panel are four indicators for communication with the patient.
# Intended Use:

Comparing the proposed device to the predicate devices, both devices utilize the same range of chemical compositions, packaging and formulations. There are no significant differences.
## Summary of Non-Clinical Tests:
In vitro testing was performed to evaluate / assess the product life, presentation of data, environmental parameters, power supply and battery life, sound levels, and environmental operating temperatures. The results of these tests confirmed that the proposed device meets the specifications for these parameters.
# Clinical Test Results:
20 patients with a definite history and diagnosis of Meniere's disease and active vestibular symptoms have been treated with middle ear pressure pulses using Meniett daily for a period of four weeks. Thereafter, the majority of patients have continued treatment up to 4 months. The dosage was standardized in all patients. The aim of treatment was to relieve patients from the attacks of vertigo and to improve balance and functionality. The results showed that the use of Meniett 20 gave the intended clinical effect in all the patients except two. None of the patients became worse while using Meniett 20. No other adverse effects of treatment have been observed in connection with the use of Meniett 20. Temporary relapses of symptoms have been observed in patients who were not able to continue the use Meniett 20. The symptoms were relieved again in these patients by a renewal of treatment with the Meniett 20. It was demonstrated that the Meniett 20 performed well under the normal conditions of daily clinical use.
### Conclusions:
Testing performed on the Pascal Medical AB Meniett 20 indicates that it is safe, effective, and performs as intended, when used in accordance with the instructions for use.

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.
