#### Discussion of Non-Clinical Tests Performed to Determine Substantial Equivalence:
# (a) Electromagnetic Compatibility/Electrical Safety
Not applicable
# (b) Biocompatibility
The materials used in the Aeroneb® Solo Nebulizer System remain unchanged. Biocompatibility testing per the requirements of ISO 10993-1 was conducted on the Aeroneb® Solo Adapter and associated Oxygen Tubing. The product categorization of the Aeroneb® Solo Adapter is defined as Externally Communicating tissue contact with limited contact duration, as per 10993 Part 1 and Blue Book Memorandum #G95-1: Use of International Standard ISO-10993, "Biological Evaluation of medical Devices part 1: Evaluation and Testing".
Accordingly it was subjected to the following tests:
- Cytotoxicity Study Using the ISO Elution Method;
- ISO Systemic Toxicity Study in Mice; ●
- ISO Intracutaneous Study in Rabbits; ●
- ISO Maximization Sensitization Study.
This GLP testing was carried out at Aerogen Limited's approved subcontract test supplier, NAMSA, Northwood, Ohio, USA. The GLP study reports showed acceptable results for the Aeroneb® Solo Adapter in each of the biocompatibility tests, and thus meet the requirements of ISO 10993-1, ISO 10993-5, ISO 10993-10 and ISO 10993-11.
#### (c) Software
Not applicable
#### (d) Cleaning
The Aeroneb® Solo Adapter device is a non-sterile disposable device, for single patient use, and therefore does not require cleaning. The IFU for the Aeroneb® Solo Adapter provides
{6}------------------------------------------------
direction to the user to rinse with sterile water, which is completed to maintain the functional performance of the device and in particular, the valves.
# (e) Simulated Life Testing
Testing was completed for Valve Operating Pressure and Expected Life of the Aeroneb® Solo Adapter.
After 20 treatments (at a rate of four 3 ml doses per day over 5 days) the pressure within the device did not exceed +1.5 cm H2O when connected to a steady exhalation flow of 15 1/min or decrease below -1.5 cm H2O when connected to a steady inhalation flow of 15 1/min based on a 90 / 90% confidence / reliability.
The inlet or exhaust valve flaps did not dislodge after rinsing during intermittent therapy.
# (f) USP 661 Leachables Testing
All drug contacting plastic materials in the Aeroneb® Solo Adapter and associated Oxygen Tubing were tested to determine the level of plastic leachables. The entire Aeroneb® Solo Adapter test Article was extracted at 50℃ for 72 hours in 132mL of purified water. A control of purified water was similarly prepared without the test article. The test results demonstrated that all extractables were within the acceptable limits for drug contacting polymer based materials as per USP <661>. Under the conditions of the tests, no significant extractables originated from the test article.
In addition, an Exhaustive Extraction and Simulated Use Extraction were also carried out on the entire Aeroneb® Solo Adapter test Article, which demonstrated that the amounts of COPC that could potentially leach from the Aeroneb® Solo Adapter are not toxicologically significant, and will not elicit an adverse biological response in the patient population expected to use the device.
#### (g) Aerosol Characterization
The table below shows the results of aerosol performance testing using an 8 stage cascade impactor running at a continuous flow rate of 28.3 LPM. Indicated ranges correspond to confidence intervals with a confidence level of 95%.

|-------------------------------|--|--|
|-------------------------------|--|--|
#### Conclusion:
The Aeroneb® Solo Nebulizer System is approved for use in adult and pediatric (29 day or older) populations, and the Aeroneb® Solo Adapter will be used as an accessory for off vent use within these populations. Furthermore, Aerogen Limited has determined based on the review and results of testing detailed above; that the Aeroneb® Solo Nebulizer System with the Aeroneb® Solo Adapter, and the inclusion of a reference in the labeling (IFU) to the use of Nasal Cannula as an alternate patient interface on/off ventilator when the Aeroneb® Solo Nebulizer is placed dry side of a humidifier; is in our opinion, substantially equivalent to the existing 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.
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.
