The Moses fibers are intended for use with compatible laser systems in surgical procedures involving endoscopic ablation, vaporization, excision, incision, coagulation of soft tissue, and lithotripsy of calculi in the medical specialty of urology.
Device Story
Moses D/F/L Laser Fibers are single-use, straight-firing delivery devices transferring Holmium (Ho:YAG) laser energy from a compatible laser console to a treatment site. Energy travels through a silica glass core to the distal tip; Moses 200 features a ball tip for improved passability through deflected flexible endoscopes, while 365 and 550 models feature flat tips. An embedded RFID chip enables console recognition and enforces single-use limits. Used in urology clinics or ORs by physicians; the device acts as a conduit for laser energy to perform tissue ablation or lithotripsy. Clinical benefit is derived from the precise delivery of laser energy for minimally invasive surgical intervention. The device is EtO sterilized and has a 3-year shelf life.
Clinical Evidence
Bench testing only. Testing included biocompatibility (cytotoxicity, irritation, sensitization, acute systemic toxicity, material-mediated pyrogenicity) and performance testing (tensile strength, transmission efficiency, bend radius, durability, connector temperature, aiming beam visibility, RFID transponder content, and shelf-life/packaging integrity at T=0 and T=37 months). Summative usability evaluation was performed for the mounting card.
Technological Characteristics
Single-use, straight-firing silica glass core fibers. Distal tips: ball (200 model) or flat (365/550 models). Energy source: Ho:YAG laser (external console). Connectivity: RFID chip for console communication. Sterilization: EtO. Shelf life: 3 years.
Indications for Use
Indicated for patients undergoing urological surgical procedures requiring endoscopic ablation, vaporization, excision, incision, coagulation of soft tissue, or lithotripsy of calculi.

## 2. Device Description
The Moses D/F/L Laser Fibers are single-use, straight-firing delivery devices that transfer laser energy from the laser console to the treatment site. The laser energy travels within the fiber’s silica glass core and exits through the distal end of the fiber. The Moses 200 D/F/L Fiber consists of a Ball Tip which aids in the passability of the small core fiber through a deflected flexible endoscope. Moses 365 D/F/L and Moses 550 D/F/L Fibers have a flat distal tip. The Moses Fibers also include an embedded RFID Chip, allowing the Laser Console to recognize fibers and limits the fibers to a single use. The Moses fibers are available in a single, box-one configurations. The Moses fibers are compatible with the (Lumenis) Pulse 120 Laser System,

used for the energy delivery of the Holmium Laser Energy (Ho:YAG) from the Console. All Moses fibers have a 3-year shelf life and are provided EtO Sterilized.
The Principles of Operation of the proposed Moses D/F/L Fibers remain unchanged from the predicate Moses Fibers included in K170121 (Lumenis Family of Holmium Surgical Lasers and Delivery Devices and Accessories).
# 3. Intended Use/Indications for Use
The Moses fibers are intended for use with compatible laser systems in surgical procedures involving endoscopic ablation, vaporization, excision, incision, coagulation of soft tissue, and for lithotripsy.
# 4. Comparison to Predicate Device
The proposed Moses Fibers have the same technological characteristics and fundamental design as the legally marketed predicate Moses Fibers (K170121).
| Subject Device Intended Use | Predicate Device (K170121) Intended Use |
| --- | --- |
| The Moses fibers are intended for use with compatible laser systems in surgical procedures involving endoscopic ablation, vaporization, excision, incision, coagulation of soft tissue, and for lithotripsy. | Intended for use in surgical procedures involving open, laparoscopic and endoscopic ablation, vaporization, excision, incision, and coagulation of soft tissue in medical specialties including: urology; urinary lithotripsy; arthroscopy; discectomy; E.N.T. surgery; gynecological surgery; pulmonary surgery; gastroenterology surgery; dermatology and plastic surgery and general surgery |
While the Intended Use is not exactly the same, the proposed intended use of the Moses Fibers is a reduced scope from the predicate devices. The predicate intended use includes all proposed intended uses. The Product Code, Class, Environment Use, and Users are the same.
Additionally, the following characteristics were assessed to be the same or similar:
- Principles of Operation
- Dimensions
- General Design Features
- User Interface
- Sterility
- Nature of Patient Contact and Patient-Contacting Materials
The differences in technological characteristics have been assessed and do not raise any new questions of safety or effectiveness. The proposed changes to Packaging and Shelf Life were assessed through Performance Bench Testing, utilizing acceptable methods to evaluate the differences, and does not introduce new safety concerns that would impact the device's intended use or substantial equivalence. This evaluation demonstrates that the Moses D/F/L Laser Fibers are substantially equivalent to the predicate device (K170121).

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.
