### Predicate Device Information
Cimilre F1: K162870
The predicate device has not been subject to a design-related recall.
### Device Description
The Mya Joy PLUS Breast Pump is an electric breast pump powered by an external AC-DC power supply or by an internal rechargeable lithium ion battery. The device is provided non-sterile.
{4}------------------------------------------------
The device is intended to be used by lactating women to express and collect milk from their breasts. Pumping can be performed on either one breast (single pumping) or both breasts at the same time (double pumping).
The Mya Joy PLUS Breast Pump utilizes a DC-powered motor driving a diaphragm-type vacuum pump and an electromechanical solenoid which are controlled electronically to provide a range of user-selectable vacuum (suction) levels at various pre-determined cycle frequencies.
The Mya Joy PLUS Breast Pump has a backlit LCD display, which shows pumping mode, suction level, timer, and battery level. The device also has four soft-touch buttons allowing the user to power the device on/off, switch between stimulation and expression pumping modes and control vacuum strength within each mode, 6 levels of vacuum strength in stimulation and 12 levels in expression.
The Mya Joy PLUS Breast Pump is intended for a single user in the home environment. When properly connected, the Ameda Hygienikit pumping kit transfers the vacuum generated by the powered pump to the breast enabling expression and collection of milk. A diaphragm in the breast flange assembly physically isolates pump and tubing from the space where milk is expressed, flows and is collected, effectively protecting the breast milk from contamination.
The pump allows lactating women to express milk at their own convenience and maintain their milk supply.
The base model of the Mya Joy PLUS Breast Pump contains a pump, pumping kit, AC adapter with detachable USB-C cable, and a lanyard. Optional accessories, such as a carrying bag or spare parts for the pumping kit, may be included in the packaging of other product offerings.
# Indications for Use
The Ameda Mya Joy PLUS breast pump is a single-user, powered breast pump intended to express and collect milk from the breasts of lactating women.
# Comparison of Technological Characteristics
The indications for use of the Ameda Mya Joy PLUS breast pump and the intended use are the same as those of the predicate device, the Cimilre F1 powered breast pump (K162870). It has a nearly identical external shape, user interface, similar vacuum motor, including noise dampening material.

{6}------------------------------------------------
The principal differences in technological characteristics between the subject device and the predicate are few. Both devices utilize lithium-based technology for the internal rechargeable battery. The subject device has a higher battery capacity than the predicate (1500mAh). The longer time before automated shut-off in the subject device is not consequential because users will likely finish a pumping session before auto-cutoff is reached in either device. These power-related differences do not alter the intended use of the device from that of the predicate. Moreover, these differences do not raise different questions of safety and effectiveness.
Vacuum performance characteristics differ slightly. The subject device includes additional range in stimulation mode and two ranges in expression mode relative to the ranges available in the predicate device. The subject device delivers lower maximum pressure (250 mmHq) than the predicate. Finally, while the cycle speed of the subject device is very similar to that of
{7}------------------------------------------------
the predicate device in expression mode, the cycle speed of the subject device is nearly twice as high as that of the predicate in the stimulation mode. These differences in vacuum pressure, speed and settings do not alter the indications for use or intended use of the device, and they do not raise new questions of safety and effectiveness.
Both kits feature an integrated breast flange design, namely flanges that are molded together with the connections to the pump and bottle threads. The only difference between subject and predicate devices is the shape of the diaphraqm. In the subject device, the cylindrical shape of the diaphragm results in tubing which rises vertically from the flange assembly, while the flat circular shape of the diaphragm in the predicate device allows tubing to lie horizontally. This difference in design does not affect pump performance, does not alter intended use, and raises no new questions of safety and effectiveness.

# Performance Testing
The Ameda Mya Joy PLUS breast pump was tested to demonstrate it meets stated performance specifications. Testing involved measurement of vacuum at user-selectable settings in both stimulation and expression modes for pumping at a single breast (single pumping) or both breasts simultaneously (double pumping). Testing was conducted separately under two states of
{8}------------------------------------------------
power: (1) externally supplied by an AC/DC adapter and (2) internally supplied from a rechargeable lithium ion battery. Specifications were met under all conditions.
Testing was also performed to characterize noise emitted from the pump during operation, the ability of the pump to operate within stated operating and storage conditions, and the ability of packaging to withstand simulated transportation conditions.
Testing also confirmed device life and battery operating time.
Test results demonstrated that the Ameda Mya Joy PLUS breast pump met predetermined acceptance criteria.
# Summary of Clinical Tests
Clinical testing was not required to demonstrate the substantial equivalence of the Ameda Mya Joy PLUS breast pump to its predicate device.
# Conclusion
The Ameda Mya Joy PLUS breast pump has the same intended use and very similar technological characteristics as the predicate device. The minor differences in technological characteristics do not raise different questions of safety and effectiveness. In addition, performance testing demonstrates that the subject device is as safe and effective as the predicate.
Therefore, Ameda concludes that the Ameda Mya Joy PLUS breast pump is substantially equivalent to the legally marketed predicate device, the Cimilre F1 powered breast pump.
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.
