- Device Description: The Cellfina System is intended to provide precise focal release of subcutaneous tissue for improvement in the appearance of cellulite. The system consists of a sterile, single-use, disposable kit (CK1) and an electromechanical, non-sterile, 50-use motor module (CM1).
- Indications for Use: The Cellfina System is intended for long term improvement in the appearance of cellulite in the buttocks and thigh areas of adult females as supported by clinical data demonstrating no significant reduction in treatment benefits up to 3 year of observation.
# Substantial Equivalence Comparison:
The subject device and the predicate device are similar in the following ways: same regulation number and product code, anatomical use area, clinical use group (doctor's office, clinic), energy type with the same mechanism of action, packaging materials and configuration are unchanged, there are no differences in patient contacting materials, design of the CK1 Disposable Kit is the same, and the sterilization SAL is the same (EO, SAL 10th. Both devices are compliant to IEC 60601 standards and EMC standards.
The subject device differs from the predicate device in that the subject device is intended for 3 year efficacy whereas the predicate is intended for 2 year efficacy. In addition, the subject device's CK1 Disposable Kit has a shelf life of 24 months, whereas the predicate device had a shelf life of 12 months. The subject device CK1 is now qualified for a fully validated sterilization cycle, whereas the predicate went through a sterilization batch release process. The Subject Motor Module is intended for use up to 50 uses, whereas the predicate was intended for use up to 15 uses. The subject Motor Module is now validated for two types of cleaning methods (IPA based wipes and Chloride based wipes). The housing material for the enclosure and power button also changed from ABS and Elastomer to Makroblend and Wacker Elastosil, respectively in order to include a more robust material type that would withstand the new cleaning method. These are non-patient contacting materials and therefore additional biocompatibility testing was not necessary. The predicate device was only validated for one type of cleaning (Chloride based wipes). The subject device Motor Module includes minor tolerance changes to allow for injection molding, whereas the predicate was machined. Minor changes to location of epoxy, simplification of design to remove metal pin and using screws instead of heat staking were made to accommodate a 50 use "use life". The subject device will have a separate IFU for the CK1 and CM1, whereas the predicate utilized identical IFUs with repetitive information.
### Non-clinical Performance Data:
Bench testing was performed to verify that the modifications to the subject device do not impact the safety or effectiveness of the device. Retesting for EMC and IEC 60601 was completed for the motor module to ensure that the changes in design would have no impact on safety or efficacy. Shelf life testing and use life testing were conducted on the CK1 and CM1 respectively for the changes in shelf and use life, which demonstrated full functionality. Cleaning and disinfection testing was conducted for the addition of the cleaning method for the motor module

with no impact to device performance. Sterilization was completed for the CK1 disposable kit in order to remove the requirement for batch release testing. The SAL level and sterilization method (EO) remains the same.
# Clinical Performance Data (In-Vivo):
The safety and effectiveness of the Cellfina System was evaluated in a pivotal clinical study conducted under IDE G120116. The IDE was modified to allow for extended follow-up clinical performance data to be gathered for safety and efficacy at 3 years. No additional treatments were performed.
During the course of the 3 year Clinical study, 10 of the 55 subjects were lost to follow up. The reason for loss to follow up ranged from inability to contact the subject after multiple attempts to the subject removing herself from the study. Imputation analyses were performed for the 10 missing subjects from the 3 year report and carried out using the last observation carried forward (LOCF) for both the primary and 1st secondary endpoints using a paired t-test as well as multiple imputation for the primary effectiveness endpoint only, which met the study endpoint. The overall study success was met, despite the reduction in follow up participation at 3 years with a clinically significant, long term improvement in the appearance of cellulite in the treated subjects. The table below is based on the LOCF data and accounts for the 10 missing subjects:

There were no subjects who reported pain at the 3 year follow-up. |
# Conclusion:
This Traditional 510(k) Premarket Notification is for an expansion to the indications for use (from 2 years to 3 years). Additionally, the motor module (CM1) use life has been extended from 15 uses to 50 uses and the shelf life of the disposable kit (CK1) has been extended from a 12 month shelf life to a 24 month shelf life. Labeling changes have also been implemented to reflect the above described changes. Additional testing was performed for compliance to Amendment 1:2012 (Edition 3.1) of 60601-1 and EMC 60601-1-2:2007 3rd Edition.
These changes do not pose any new questions of safety, product output or efficacy. As demonstrated through bench testing and clinical data, the subject device Cellfina System is as safe, as effective, and performs as well as the legally marketed predicate device (K153677), and as such, is substantially equivalent.

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.
