Device Story
MINNIE is a portable, noninvasive radiofrequency (RF) system for facial wrinkle reduction. System comprises touch screen interface, programmable microcontroller, RF power module, and four handpieces (one bipolar, three unipolar). Operator (clinician) selects parameters to deliver 550–800 kHz RF energy (up to 30W) and thermal energy to treatment site. Energy delivery induces thermal effects in skin tissue to improve appearance of wrinkles and rhytides. Output is controlled via handpiece application; clinical effect monitored by provider via visual assessment (Fitzpatrick Wrinkles Scale). Benefits include non-surgical improvement of facial skin texture.
Clinical Evidence
Prospective clinical study of 52 subjects (36 female, 16 male). Groups: Control (n=8), Sham (n=11), Active (n=33). Active group received 4 treatments 2 weeks apart (550-800 kHz, max 30W RF/thermal). Primary endpoint: ≥2 point decrease in Fitzpatrick Wrinkles Scale (FWS). Results: 100% of active group met success criterion at 1 month. Follow-up at 3 and 6 months showed sustained improvement. Adverse events: 4 cases of moderate erythema, resolved with topical treatment. No improvement in control/sham groups.
Technological Characteristics
Portable RF system; 550-800 kHz frequency; max 30W RF/thermal output. Includes touch screen, microcontroller, and 4 handpieces (1 bipolar Ø 36mm, 3 unipolar Ø 36/60/80mm). Complies with IEC 60601-1, IEC 60601-1-2, and IEC 60601-2-2. Software-controlled energy delivery.

An extended comparison is presented in Document Substantial equivalence discussion.
## Performance Standards:
MINNIE complies with the following Recognized standards:
- · IEC 60601-2-2:2009 Medical Electrical Equipment Part 2-2: Particular requirements for the basic safety and essential performance of high frequency surgical equipment and high frequency surgical accessories (with US/Canada deviations)
- IEC 60601-1-2:2007 Medical Electrical Equipment Part 1 General requirements for safety 2. Collateral standard: Electromagnetic compatibility - Requirements and tests and the following voluntary standard
- IEC 60601-1:2005 Medical Electrical Equipment Part 1 General requirements for safety .
In addition it complies with European Directive 93/42/EEC for Medical Devices (Annex IX - Rule 9).
## Clinical Performance Study:
A clinical study has been carried out in order to assess the safety and effectiveness of MINNIE. To measure effectiveness, success criterion was defined as at least 2 points decrease in in the FWS score. Adverse events were monitored to evaluate safety.
The population included 52 subjects (36 females, 16 males). At the enrollment visit, their condition was evaluated using Fitzpatrick Wrinkles Scale (FWS) and they were randomly assigned to 3 groups:
Group A: control (only visit, no stimulation), 8 subjects Group B: sham (electrical stimulation), 11 subjects Group C: radiofrequency treatment, 33 subjects. (active treatment group)
Evaluations were performed by the investigator on live study subjects and documented with clinical photographs. To confirm the in-vivo scores, evaluations from a team of 3 physicians blinded to the randomization group were carried out on photographs. There were no differences in the scoring of the evaluators.
Subjects in Group A received no treatment, and subjects in Group B received electrical stimulation (sham treatment). All the subjects included in Group C received a cycle of 4 treatments 2 weeks apart. The treatments for Group C were applied using monopolar and bipolar electrodes delivering 550 kHz to 800 kHz energy up to a maximum 30 W radiofrequency energy and 30 W thermal energy for specified duration.
At 1 month after the end of the cycle, a new evaluation was carried out using the FWS scale. Data analysis showed a substantial improvement, as all the subjects treated met the above success criterion (at least 2 points decrease on the FWS).
The initial clinical protocol did not include a scheduled follow up visit for clinical evaluation at 3 and 6 months after last treatment. Upon FDA request clinical information with FWS scores and clinical photographs as well as investigators evaluation were submitted, the results are summarized below:
All subjects were followed up at 3 and 6 month time points. Outcomes for Group C at the 3 and 6 months follow-up visit are:
- י all of the patient population treated demonstrated an improvement from baseline.
- at 3 months, in 42% of cases in the C group there was no change in the FWS score recorded at the completion of the treatment cycle.
- at 6 months, 44% of the subjects in the C group showed an improvement with respect to the FWS score recorded at 3 months, confirming the continuation of the treatment effect.
{2}------------------------------------------------
30% of the requested study subject photographs at 6 months were not provided to the Agency for review due to patient privacy privilege.
The only adverse events reported in this study were 4 cases of moderate skin erythema which resolved with the use of antihistamines and/or topical corticosteroids and skin emollients for a short period of time (maximum of 3 days).
No decrease in FWS was noticed in any subject in Group A (control) or Group B (sham) at the 3 or 6 month follow-up time points.
## Rationale for substantial equivalence:
A comparison of Indicated Use Statement and technological characteristics to other predicates has been performed. The indications for use of the MINNIE device were found to be equivalent to the predicate devices and do not raise new questions of safety and effectiveness. Performance testing further demonstrated that the device can output the listed monopolar and bipolar energy, and therefore demonstrated that the technological characteristics can be considered substantially equivalent. As summarized above, clinical performance data was collected to demonstrate safety and effectiveness. These data show that subjects obtained an improvement in the FWS immediately following treatment, and maintenance of that improvement was obtained at 3 and 6 months. Therefore, the indications for use, technical characteristics and clinical study information provided demonstrates that MINNIE is substantially equivalent to the predicate devices.
### Conclusion:
The MINNE device shares the same indications for use, similar design and functional features, thus is substantially equivalent to the predicate devices.

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.
