The AeroChamber Plus* Flow-Vu* Anti-Static Valved Holding Chamber is intended to be used by adult and pediatric patients who are under the care or treatment of a physician or licensed healthcare professional. The device is intended to be used by these patients to administer aerosolized medication from most pressurized Metered Dose Inhalers and Soft Mist Inhalers. The intended environments for use include the home, hospitals and clinics. It is a single patient, multiple use device.
Device Story
AeroChamber Plus Flow-Vu is a valved holding chamber (VHC) designed to interface between a pMDI or SMI and a patient. It contains an aerosol plume from the inhaler, allowing for a delay between device actuation and patient inhalation. A valve acts as a movable barrier, directing patient exhalation away from the chamber to minimize aerosol loss. Used in home, hospital, or clinic settings by patients under professional care. The device helps ensure consistent delivery of aerosolized medication, potentially improving drug deposition. It is a single-patient, multi-use device.
Clinical Evidence
No clinical data. Substantial equivalence is supported by bench-only aerosol characterization testing comparing SMI formulations with and without the VHC, and mechanical/biocompatibility testing for the new mask configuration.
Technological Characteristics
Constructed of thermoplastic polymer, thermoplastic elastomer, and silicone. Dimensions: 5.86" length x 1.75" diameter; 149 cc volume. Operates as a valved holding chamber. Non-sterile, single-patient, multi-use. Biocompatibility testing conducted per ISO 10993 standards (parts 3, 5, 10, 11, 12, 17, 18).
Indications for Use
Indicated for adult and pediatric patients under the care of a physician or licensed healthcare professional for the administration of aerosolized medication from pressurized Metered Dose Inhalers (pMDI) and Soft Mist Inhalers (SMI).
Regulatory Classification
Identification
A nebulizer is a device intended to spray liquids in aerosol form into gases that are delivered directly to the patient for breathing. Heated, ultrasonic, gas, venturi, and refillable nebulizers are included in this generic type of device.

## 4. Device Description
The AeroChamber Plus* Flow-Vu* Anti-Static Valved Holding Chamber (VHC) is a holding chamber used for the administration of aerosolized medications. The AeroChamber Plus* Flow-Vu* Anti-Static VHC line of products is designed to be used with a broad range of FDA approved pressurized metered dose inhaler (pMDI) or soft mist inhaler (SMI) pharmaceutical formulations prescribed by a healthcare provider. It is a single patient, multi-use device intended to be used by patients who are under the care or treatment of a licensed health care professional. This device is not used with a specific drug nor is it distributed with such drugs.
# 5. Principle of Operation
The VHC has two primary modes of operation, one is to contain an aerosol plume from a metered dose inhaler or soft mist inhaler and the second is to deliver the aerosol to the patient. The device is designed to allow for the potential delay between actuation of the metered dose inhaler and the inhalation breaths of the patient. The containment is accomplished by a valve acting as a movable barrier between the chamber and the mouthpiece or mask. The valve acts to direct the patient's exhalation away from the chamber to minimize any aerosol loss to the atmosphere between inhalation breaths. The chamber is sized to ensure the proper amount of aerosol is available for delivery through the valve.

Change in Intended Use for AeroChamber Plus* Flow-Vu* Anti-Static VHC product line:
The non-clinical data demonstrate that the AeroChamber Plus* Flow-Vu* Anti-Static VHC (facemask and mouthpiece configurations) used in combination with Soft Mist Inhaler formulations is comparable to use of a SMI formulation alone. Use of the VHC device with an SMI does not raise any new questions of safety and/or effectiveness.
Addition of AeroChamber Plus* Flow-Vu* Anti-Static VHC Adult Small Mask configuration:
The non-clinical data demonstrate that the AeroChamber Plus* Flow-Vu* Anti-Static VHC, Adult Small Mask is substantially equivalent to the predicate (AeroChamber Plus* Flow-Vu* Anti-Static VHC, Adult Large Mask). Use of the subject device does not raise any new questions of safety and/or effectiveness.
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.
