# Indications For Use:
Revolver Laser Probes, Revolver Illuminated Laser Probes, and Revolver Illuminated Probes:
For use in vitreoretinal surgery to perform endo-ocular laser photocoagulation treatments.
The Revolver Laser Probes can only be used with a medical laser at operating wavelengths of 500nm to 900nm. The Revolver assemblies containing illumination should be used with the light wavelength range of 425nm to 700nm.
# Device Description:
The Katalyst Revolver Laser Probes are cables made out of one fiber optic (Single-Use), one laser adapter(Reusable), and one handle (Reusable) for surgeon manipulation, metal tubing extending from the handle which penetrates into the surgical site and protective sheath over the fiber.
{4}------------------------------------------------
The fiber for laser transmission is made out of glass, and is restricted for use within the wavelength range of 500nm to 900nm.
The fiber for illumination transmission is made out of either glass or plastic.
The illumination fiber (glass or plastic) is between 100 and 750 microns in size (measure based on the core diameter). The laser fiber (glass) is between 150 and 300 microns in size (measure based on the core diameter).
The tubing is provided in four different variations are referred to as straight, Curved, Flex-Curved, Steerable and Articulating. The configuration is chosen based on the surgeon requirements. The total length of the device is 8-10 feet.
In case of laser and illumination functionalities provided by the same probe, the common protective sheath runs for 1-2 feet, while both branches run for the remainder of the 8-10 feet with each branch having its own protective sheath and each branch ending with its own adapter. The same tubing will then hold within its internal diameter the laser fiber and the illumination fiber.
The Revolver Laser Probes can only be used with a medical laser at an operating wavelength range of 500nm to 900nm. The Revolver Illumination Probes can only be used with the light wavelength range of 425nm to 700nm.

#### SUMMARY OF EQUIVALENCE
The technological characteristics are identical to the predicate device, in terms of the indication for use, target population, optical output, materials, performance, sterility, biocompatibility, anatomical sites, human factors, compatibility with environment and other devices. The electrical, thermal and radiation safety is identical, because it's not applicable to any of the devices.
The Revolver Probes design is similar to the predicate devices. The Revolver Probes comes four different gauges (20g, 23g, 25g, 27g) and four different tip configuration (i.e., straight, curved, flex-curved, and steerable). The tip configuration is straight or curved for the predicate devices. The difference in tip variations of the Katalyst Revolver Probes and the straight or curved tips of the predicate devices does not affect the safety or effectiveness of the Katalyst Revolver Probes when used as indicated. A surgeon may use any variation of the tip, straight. curved, flex-curved and steerable: in an identical manner; (2) to perform an identical surgical procedure; and (3) to achieve the same surgical result.
The predicate devices come in 20g, 23g, and 25ga in laser probes, and 20ga in Illuminated laser probes. Katalyst Revolver Probes come in 20ga, 23ga, and 27ga, for laser, illumination and laser illumination probes. The addition of the various gauge sizes does not affect the safety and effectiveness of the device. All the micron sizes are within the range of the pervious cleared predicate device.

Image /page/8/Figure/1 description: The image is a graph that shows the transmission loss in dB/m as a function of wavelength in nm. The x-axis represents the wavelength, ranging from 400 to 1100 nm, and is divided into three regions: Ultra Violet, Visible Band, and Infra-red. The y-axis represents the transmission loss, ranging from 0.1 to 30.0 dB/m. There are two curves on the graph, labeled "INDUSTRIAL" and "OPTICAL", which show the transmission loss for different materials.
Furthermore, the predicate devices are single-use devices. The revolver probes are assembled with single-use, and reusable components. Revolver probes comprise three components, handle, fiber and an adapter. The handle and adapter are reusable and are provided nonsterile. The replaceable fiber is a single-use component, and is provided sterile. This change from the predicate device does not have any impact on the safety and effectiveness of the device. The predicate devices and The Revolver Probes are intended as accessories to devices used to coagulate or cut tissue of the eye, orbit, or surrounding skin by a laser beam and to provide illumination during vitroretinal surgery. The Revolver Probes are substantially equivalent to the previously cleared devices.
#### Conclusion
The Katalyst Revolver Probes were shown to be substantially equivalent to previously cleared devices with respect to intended use, indications for use, technological characteristics, performance characteristics, and biocompatibility.

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.
