# General Device Description
The subject and predicate acapella® devices are within Smiths Medical's product family for a therapeutic spirometer hand-held vibratory positive expiratory pressure (PEP) device provided to the end-user as a non-sterile, single patient use. The subject device helps aid in the mobilization and expectoration of secretions that accumulate in the lungs of adult and pediatric users who may have Cystic Fibrosis, COPD, asthma, including lung diseases with secretory problems, and patients with atelectasis.
The subject device provides PEP therapy to a patient by producing airflow vibrations that can be delivered in any position to effectively mobilize secretions, open airways and deliver medication (nebulization). These devices have been found to give independence to patients with chronic respiratory diseases, as the therapy can be done at the patient's convenience without the need for clinical assistance.
### Principle of Operation
The acapella® Choice Blue Vibratory PEP Device using a non-return valve that upon patient exhalation will create positive end expiratory pressure and oscillations. The device is adjustable to different frequencies. Rotation of the knob between the limits of the cam surfaces allows the
{4}------------------------------------------------

# Summary of Technological Characteristics
The technology for delivery PEP therapy is unchanged between the subject and the predicate devices. The subject device shares the same technological characteristics as the 510(k) cleared for the predicate device, acapella® DH (K002768); these characteristics include:
- . Provide controllable and variable resistance to the expiratory phase of breathing and therefore creates increased trans-pulmonary pressure within the lung.
- Create vibrations that mimic the oscillatory frequency of cilia. This aids in loosening . secretions from the walls of the airways by altering the viscoelastic properties of secretions.
- Contain a flow tube to create a channel for air to pass through and for the vibrations travel back to the user.
{6}------------------------------------------------
# s medical bringing technology to life
# K181660 acapella® Choice Blue
- Have an adjustable resistance dial raises and lowers the magnet based on the users' . exhalation capacity.
- . Contain a mouthpiece that connects the users' mouth to the device.
- . Provide the ability to connect a nebulizer in-line that allows the user to inhale the aerosolized drug and then exhale through the PEP device.
The differences between the subject and predicate device are minimal and include differences in the materials of the outer and internal components. The subject device is now able to be opened for cleaning by the user throughout the lifetime of the device, whereas the predicate is a closed system. Smiths Medical has determined these two (2) modifications do not affect the device's intended use, indication for use or alter the device's fundamental scientific technology of Positive Expiratory Pressure therapy.
# Summary of Non-Clinical Testing
Non-clinical testing of the components comprising each configuration of the subject acapella® Choice Blue Vibratory PEP Device were assessed and tested appropriately to design controls; i.e. design verification, design validations. Testing listed below passed and were verified against their requirements and acceptance criteria:
- Temperature exposure and accelerated aging
- . Performance testing (bench) - drop, online therapeutic output, orientation, breakaway pressure, inhalation mode resistance and stutter tests.
- Nebulizer specification verification ●
- Reprocessing (cleaning and disinfection) verification ●
- Packaging (transport and distribution) per ASTM D4169 .
- . Biocompatibility per ISO 10993-1
- Biocompatibility per ISO 18562 for gas pathway safety .
Additional drug delivery verification testing was conducted for the nebulizer performance with three (3) different aerosol medications (i.e., albuterol sulfate, cromolyn sodium, ipratropium bromide). Specifications were established via a performance test using an eight-stage cascade impactor at a flow rate of 28 L/min equipped with USP induction port throat. Three (3) device samples were tested per each drug. Aerosol was sampled directly from the outlet. The acceptance criteria of the test were that the aerosol performance of any medication, nebulizer, and flow rate would not be statistically different at a confidence level of 95% between the acapella® Choice Blue Vibratory PEP Device and acapella® DH as compared to the nebulizer by itself.
Drug delivery performance of acapella® Choice Blue Vibratory PEP Device combined with a standard nebulizer configuration was compared to same nebulizer configuration without the acapella® Choice Blue Vibratory PEP Device. The delivery of aerosolized drugs with acapella® Choice Blue Vibratory PEP Device when connected to a small volume nebulizer was found to be clinically comparable to the performance of the nebulizer alone.
# Summary of Differences and Discussion of Substantial Equivalence
The Smiths Medical acapella® Choice Blue Vibratory PEP Device is substantially equivalent to the predicate device, acapella® DH, K002786, based on device characteristic comparisons. These characteristics include the similar intended use, same clinical application, same general design, same useful life, same packaging and same principle of operation and similar performance.
{7}------------------------------------------------
510(k) SUMMARY
bringing technology to life
# K181660 acapella® Choice Blue
The indications for use are similar for patient population, environment and indication. Contraindications are identical to the predicate. The principal of operation is identical to the predicate. The technological characteristic differences are minimal and have been demonstrated to be substantially equivalent through comparative testing to the predicate and do not increase patient risk. Cleaning and disinfection methods are different, and the differences validated. Performance characteristics of the subject and predicate devices, both with and without a nebulizer, have been evaluated and both meet the acceptance criteria and are therefore substantially equivalent.
# Substantial Equivalence Conclusion
Smiths Medical concludes the differences between the subject and predicate device do not impact the indications for use, intended use, mechanical and/or fundamental scientific technology of the device, do not raise new or different questions of safety risks imposed on the patient or device use and that the subject device is as safe and effective as the predicate device; therefore, the subject device, acapella® Choice Blue Vibratory PEP Device, is considered substantially equivalent to the predicate.

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.
