#### Device Description
The PARI O-PEP (Oscillating Positive Expiratory Pressure) is a small, single patient use, reusable oscillating PEP therapy device. The PARI O-PEP is a respiratory therapy device designed for temporary application to mobilize secretions or mucous in the lower respiratory tract, strengthen the respiratory tract and alleviate shortness of breath. The patient exhales repeatedly into the device against a movable ball, causing a vibration that is transmitted to the lungs. This causes the deeper respiratory tract to open. By doing this, secretions are mobilized and able to move up the airways. The device is non-sterile, prescription-use only, intended for use in hospital, clinic, or home environments.
#### Medical Condition Treated
The PARI O-PEP is intended to help patients with respiratory conditions clear mucus and secretions from their airways.
#### Indications For Use
The PARI O-PEP is intended for use as a Positive Expiratory Pressure Device, and is designed to help patients improve secretion clearance. The PARI O-PEP is intended for adult and pediatric patients ages 5 and older, for use in home, hospital, and sub-acute institutions.
#### Technological Characteristics Compared to Predicate Device

### Discussion of Differences
The design and intended use of the subject and predicate devices are similar, since both sets are oscillating resistance devices for prescription use, and aid patients with mucus secretion through the airways via Positive Expiratory Pressure. Product codes and regulation numbers for the subject device and predicate devices differ; however, devices under both regulations are used to transmit vibrations through the patient's chest wall to aid in freeing mucus and improving ventilation. Performance testing demonstrates that the PARI O-PEP and predicate Flutter D devices were tested to compare oscillation frequency and expiratory resistance. Results demonstrate that the PARI O-PEP device produces comparable oscillation frequencies across a range of flow rates and pressure ranges.
### Non-Clinical Test Summary
PARI O- PEP was tested to compare performance to the predicate Flutter device and satisfy applicable guidance, including:
- Expiratory resistance: PARI O-PEP expiratory pressure level was compared to the predicate Flutter device across a range of flow rates between 5 and 30 LPM and angular positions of 0 and 30 degrees, and was found to be substantially equivalent to the predicate device for all variables.
- . Oscillating frequency: PARI O-PEP oscillating frequency was compared to the predicate Flutter device across a range of flows between 5 and 30 LPM and angular positions of 0 and 30 degrees, and was found to be substantially equivalent to the predicate device for all variables.
- . Biocompatibility: Testing demonstrates that the subject device meets requirements in accordance with: ISO 10993-1: Biological Evaluation of medical devices – Part 1: Evaluation and testing within a ■
- risk management process
- . ISO 10993-5: Biological Evaluation of medical devices – Part 5: Tests for in vitro cytotoxicity
- . ISO 10993-10: Biological evaluation of medical devices – Part 10: Tests for irritation and skin sensitization
- . Cleaning efficacy validation: Testing demonstrates that the subject device meets requirements for cleaning of a reusable medical device in accordance with recognized guidelines, including:
- 트 AAMI TIR No. 30, 2011: A Compendium of Processes, Materials, Test Methods, and Acceptance Criteria for Cleaning Reusable Medical Devices
#### Clinical Performance Summary
Clinical testing was not completed/is not required to show substantial equivalence.
#### Conclusion
The sponsor has demonstrated through performance testing, design and features, and non-clinical testing that the proposed device and predicates have been found to be substantially equivalent.
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.
