## Device Description
Avéli is a sterile, single-use manual instrument that cuts fibrous tissue (septa) beneath moderate to severe cellulite for temporary reduction in the appearance of cellulite in the buttocks and thigh areas of adult females. The device consists of a handle and a distal end. The handle houses components used to actuate the moving parts at the distal end of the device. The distal end of the device is advanced into subcutaneous tissue through a small incision to a procedure location. An integrated light source provides illumination and allows the user to track and advance to the procedure location. The distal end of the device contains a blunt link and a sharpened link forming a distal hook. When the handle is moved in a retrograde fashion, the distal hook next to a fibrous septum captures the septum resulting in tugging. The user feels the resistance, confirming that a septum under a cellulite depression has been identified. The user then engages a sharpened link to be exposed at the distal end of the device. The user applies additional retrograde motion to sever the fibrous septum, and then retracts the sharpened link and the blunt link into the device, allowing removal without further tissue capture. The step is repeated for each visible cellulite depression.

-Sterilization Validation (ISO 11135-1:2014, ISO 14161:2009)
## Clinical Performance Data
The in vivo performance of the device was evaluated in a pivotal clinical study. A prospective, nonrandomized, multi-center study was conducted to evaluate the safety and effectiveness of Avéli for the treatment of cellulite in the buttock and thigh areas across nine (9) investigational sites. All participants served as their own control and underwent a single treatment with Avéli. The enrolled study population included females between the ages of 26 and 54 with moderate to severe cellulite and BMI between 19 and 30. In addition, participants were excluded that smoked or had recently quit smoking (within the last 6 months).
The primary safety endpoint was achieved. There were no Serious Adverse Events (SAE) related to the device or procedure at 30 days. No Unanticipated Adverse Device Effects (UADE) occurred in the study. Therefore, as no SAE were determined to be related to the device or procedure, the primary safety endpoint for the study was achieved. There were three advice effects (ADEs) that occurred in two participants: 1) an extended incision, 2) a skin laceration, and 3) a small scar following the skin laceration. Ecchymosis was reported by most participants. Many participants experienced tenderness or pain within the first 24 hours, and most returned to normal activities one day after the procedure.
The primary effectiveness endpoint was achieved. Effectiveness was evaluated by improvement assessment by independent physician evaluation of participant photographs. All reliability and repeatability measures were met and validated the methodology. The primary effectiveness endpoint was to demonstrate that the mean change (improvement) in the Cellulite Severity Score (CSS) is more than 1 for the study population, as determined by three independent, blinded physician evaluators of photos obtained before and 3-months after the investigational procedure.
## Conclusion
The subject Aveli device is similar to the predicate device with respect to the principles of operation. Some technological and performance characteristics of subject device are different from some of the predicate device. Pre-clinical and clinical testing was conducted to evaluate the differences in technological and performance characteristics. Results of clinical testing have demonstrated substantial equivalence of the subject device to the predicate in terms of safety and effectiveness for the intended use.

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.
