#### 6. Comparison between subject device and predicate device:
The technological characteristics of the proposed FLOW 90 Wand are the same as the predicate FLOW 50 Wand.
The main technological similarities between the subject FLOW 90 Wand and predicate FLOW 50 wand are listed below:
- COMPATIBILITY WITH THE WEREWOLF COBLATION SYSTEM: Both the FLOW . 90 Wand and the FLOW 50 Wand are to be used in conjuction with the WEREWOLF COBLATION System.
- WAND FEATURES: Both the FLOW 90 Wand and the FLOW 50 Wand are bipolar, . have Ambient feature, use-limiting feature, suction feature and can be activated using either a fingerswitch or a footpedal.
- . W AND SPECIFICATIONS: Both the FLOW 90 Wand and the FLOW 50 Wand have identical wand specifications for suction ports, number of active electrodes, total length and handle length and outer diameter of the shaft.
- . PATIENT-CONTACTING MATERIALS: Except for the adhesive, both the FLOW 90 Wand and the FLOW 50 Wand have similar patient-contacting materials for the ceramic space, shaft, shaft insulation, internal suction tubing and suction tube set.
- . PACKAGING: Both the FLOW 90 Wand and the FLOW 50 Wand are sterile, disposable and are for single-use only.
No changes or modifications have been made to the intended use, fundamental scientific technology, or principle of operation which was previously cleared in 510(k) K162074.
{7}------------------------------------------------
Image /page/7/Picture/1 description: The image shows the logo for ArthroCare. The logo consists of a stylized, abstract symbol on the left and the word "ArthroCare" on the right. The symbol is made up of several curved, parallel lines in a reddish-brown color, arranged in a circular or spherical shape. The word "ArthroCare" is written in a bold, sans-serif font, and it appears to be in a dark gray or black color.
The main technological differences between the subject FLOW 90 Wand and predicate FLOW 50 wand are listed below:
- . DISTAL TIP: The distal tip of the FLOW 90 Wand was changed to optimize performance with respect to tissue effect, ablation rate, and visualization.
- . SHAFT: The shaft of the FLOW 90 Wand features a longer shaft length than the FLOW 50 Wand (137 mm vs 135 mm). The shaft has no angle and a 90° electrode orientation in comparison to the 40° angle and a 70° electrode orientation of the predicate FLOW 50 wand device. The design change provides a variety of clinical access to the clinicians.
- ADHESIVE: HV-10 single part heat cure epoxy will be used as the adhesive in lieu of . Loctite 3984 single part heat cure epoxy.
- . ELECTRODE: The FLOW 90 Wand uses a metal injection molded (MIM) electrode with 95% tungsten alloy and a single-piece electrode construction while the FLOW 50 Wand uses a tungsten sheet electrode. The MIM electrode design has been previously approved via 510(k) K161481 (Ambient HipVac 50 Wand with Integrated Finger Switches) and enables enhanced manufacturability. The FLOW 90 Wand also features a wider and thicker electrode when compared to the FLOW 50 wand.
- STERILIZATION: The FLOW 90 Wand will be sterilized using Ethylene Oxide unlike . FLOW 50, which is sterilized using Electron Beam.
## 7. Performance Testing
Performance testing including software verification and validation, non-clinical testing (Ambient accuracy, ablation testing, use-limiting testing, design verification, electrical safety testing and biocompatibility testing) and pre-clinical testing were performed on the FLOW 90 Wand in conjunction with the WEREWOLF (RF20000) Controller to demonstrate the subject wand meets the established design criteria and supports substantial equivalence with the predicate device. Pre-clinical bench testing (ex vivo testing) was performed across multiple tissue models (muscle, tendon, cartilage and meniscus) to verify substantial equivalence to the predicate device in terms of thermal effects.
Based on all the testing performed, the FLOW 90 Wand was found to meet all design and performance specifications and no new safety and efficacy issues were raised as compared to the predicate device.

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.
