The photocoagulation system can be easily assembled by connecting the sterilized endophoto probe to the main laser device and connecting the protective filter to the laser device and surgical microscope.
This photocoagulation system enables laser endophotocoagulation while observing the affected area through the surgical microscope.
### Substantial Equivalence
The Endophotocoagulation Delivery Unit (for sterilized endophoto probe) is substantially equivalent to the predicate devices with regard to design, function, technological characteristics, intended use and performance characteristics.
The differences between the proposed and predicate devices and justifications as to why these differences do not raise safety or efficacy concerns are as follows:
• The maximum laser output and the wavelength of the proposed device is different from those of the predicate devices.
- The total length of the endophoto probes of the proposed device is different from that of the predicate devices.
- The fixed protective filter is not covered by the predicate devices.
- The cable length of the protective filters of the proposed device is different from that of the predicate devices.
The design modifications outlined in this Traditional 510(k) premarket notification do not (1) affect the intended use or the indication for use or (2) alter the fundamental scientific technology of the device. The proposed Endophotocoagulation Delivery Unit shares the substantially equivalent indications for use, the substantially equivalent technological characteristics and substantially equivalent principle of operation as the predicate devices. Therefore, based on the similarities between the devices, the proposed Endophotocoagulation Delivery Unit is substantially equivalent to
- OphthalMed 20G and 25G SMA Laser Fibers (K021696)
- . SL-1800 attachable delivery unit Multicolor Laser Photocoagulator System MC-500 (K110228)
- . Peregrine Surgical 23ga Curved Illuminating Laser Probe (K122997), a probe with a similar irradiance
{6}------------------------------------------------
- Green Laser Photocoagulator GYC-1000 (K032085) .
## Testing in Support of Substantial Equivalence Determination
We have verified and validated that the Endophotocoagulation Delivery Unit (for sterilized endophoto probe) meets its functional specifications and performance requirements, and complies with applicable international standards (ISO10993-1).
As mentioned, all necessary bench testing was conducted on the modifications, the addition of the proposed Endophotocoagulation Delivery Unit (for sterilized endophoto probe), to support a determination of substantial equivalence to the predicate devices.
## Non clinical sterility testing
The sterilization re-validation protocol was provided and the EO and ECH residual testing of the subject devices following the procedures, methods, and limits for a simulated extraction (since the product is categorized as a limited exposure device), described in the FDA-recognized standard, ANSI/AAMI/ISO 10993-7:2008 (R2012) "Biological evaluation of medical devices- Part 7: Ethylene oxide sterilization residuals" was conducted. This testing demonstrated that EO and ECH residue levels after sterilization of the endophoto probe are below the current limits for intraocular lenses, it means not exceed 1.25 micrograms and 5 micrograms (respectively), testing just the endophoto probe tip.
Regarding expiration date, the sterilized endophoto probes have a shelf life of 3 years. As the basis for setting the shelf life, the seal integrity and product sterility were tested at 3 accelerated or real years and finally concluded that the shelf life of 3 years is claimed.
## Non clinical safety testing
Both the electrical safety test report according to IEC 60601-1 and the Electromagnetic Compatibility test report according IEC 60601-1-2 were provided. The mechanical properties of all the endophoto probes were tested according to ISO 9626 and the results confirmed the ability of the device to withstand the forces it will be subjected during normal use.
## Summary of Safety and Effectiveness
The results demonstrate that the subject device complies with applicable international standards (ISO10993-1). All the necessary non clinical performance tests in support of substantial equivalence determination were conducted.
Thus the proposed Endophotocoagulation Delivery Unit (for sterilized endophoto probe) is substantially equivalent to the predicate devices.

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.
