The Renuvion/J-Plasma Precise Handpiece is available with a retractable cutting tip blade for excising tissue. The blade tip serves as an electrode to generate helium plasma.
The blade can be extended in 2mm increments from 0 to 10mm from the distal tip of the shaft via a ratcheted slider and retracted via a release latch. The device is activated via pressing the purple activation trigger. The handpiece is to be used with compatible electrosurgical generators, BVX-200H or BVX-200P, manufactured by Apyx Medical.
The Renuvion®/J-Plasma® Precise Handpiece is available in a 33 cm length for use in laparoscopic or open surgical procedures. The 33 cm is a standard length for laparoscopic instruments and are compatible with standard 5 mm trocars.
# 4. Technological Characteristics:
The subject device, Renuvion®J-Plasma® Precise Handpiece (without the transformer) is a modification to the legally marketed Primary Predicate Device (K183610 & K151325) with the same name. The modification consists of a design change to remove the transformer from the base of this pistol shaped handpiece (HP) and the addition of the Monopolar Coagulation mode. This removal of the transformer from the handpiece is being implemented to improve manufacturability and device ergonomics. There is no change to the handpiece geometry or shaft length, no change to materials and no technology or performance change other than changes in product specifications. There is no change to the Indications for Use or operational principles.
The Subject, Primary Predicate and Reference devices all use the same basic technology, deliver the same J-Plasma helium plasma energy and are compatible only with the Electrosurgical Generators (BVX-200H and BVX-200P) manufactured by Apyx Medical.
The removal of the transformer from the subject device handpiece improves ergonomics since it is 39% lighter than the Primary Predicate device (K183610 & K151325) and improves manufacturability (efficiency, cost and speed).
The removal of the transformer from the handpiece does not affect the functionality of the handpiece because the compatible electrosurgical generators (BVX-200H and BVX-200P) have transformers already built into them and are capable of supporting the subject device without any changes to these generators. The Reference Device (Renuvion/J-Plasma Precise Open Handpiece, K183610 & K170188) also functions by using the transformer in the

electrosurgical generator resulting in the following identical characteristics being shared with the subject device:
- . The internal transformer located at the base of the handpiece has been removed.
- 트 Availability of the Monopolar Coagulation feature (via optional foot pedal) for enhanced coagulation - gives the user the ability to use the Monopolar Coagulation mode on the compatible electrosurgical generator without having to switch to a secondary electrode handpiece.
- . Can access 'Contact J-Plasma' by double clicking the button or foot pedal which tells the compatible electrosurgical generator that the intention is to cut (this feature on the compatible electrosurgical generators was cleared in K170188).
Bench testing has demonstrated that the tissue effect of the subject device and the Primary Predicate device (Renuvion/J-Plasma Precise Handpiece, K183610 & K151325) using the J-Plasma mode are equivalent and bench testing has also demonstrated that the tissue effect of the subject device and the Reference device (Renuvion/J-Plasma Precise Open Handpiece, K183610 & K170188) using the Monopolar Coagulation mode are equivalent. The results of design validation demonstrate that the tissue effect meets the user needs for cutting, coagulation and ablation of soft tissue.
The Apyx J-Plasma Precise Handpiece is pictured below with the circled area depicting the location at the base of the handpiece where the transformer has been removed.

### 7. Conclusion:
The subject device, Renuvion® / J-Plasma® Precise Handpiece (without the transformer), has the same intended use, indications for use, operational principles, device ergonomics, handle geometry, handpiece geometry, and shaft length as the originally designed Primary Predicate device (Renuvion/J-Plasma Precise Handpiece, K183610 & K151325) of the same name.
The technological difference between the subject and Primary Predicate devices is the physical location of the transformer (moved from the handpiece to the electrosurgical generator) to reduce weight for easier handling as well as improve manufacturability, and availability of the Monopolar Coagulation feature (via optional foot pedal) to give the user the ability to use the Monopolar Coagulation mode on the compatible electrosurgical generator without having to switch to a secondary electrode handpiece. Bench testing has demonstrated that the tissue effects of the subject device are equivalent to the tissue effects of the Primary Predicate device (Renuvion/J-Plasma Precise Handpiece, K183610 & K151325) in the J-Plasma mode and the tissue effects of the subject device are also equivalent to the Reference device (Renuvion/J-Plasma Precise Open Handpiece, K183610 & K170188) in the Monopolar Coagulation mode.
The subject device's safety and performance have been confirmed by results of the performance bench testing and the design change has gone through the design controls process and the proper verification and validation demonstrate that the device performs as intended. Therefore, there are no differences that would raise new or different questions regarding safety or effectiveness as the subject device, Primary Predicate device and the Reference device all operate in a similar manner with an equivalent range of tissue treatment parameters.
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.
