#### Intended Use
There have been no significant changes to the Ceralas D Laser System since is was cleared by FDA (K951775, K964497). The Ceralas D Laser System has been cleared as a surgical instrument intended for incision, excision, hemostasis, coagulation, and vaporization of soft tissue in open and closed endoscopic procedures in general surgery, urology, gynecology, neurosurgery, gastroenterology,
{1}------------------------------------------------
plastic surgery, dermatology, and otolaryngology. Specific indications for the previously cleared Ceralas D Laser System include tonsillectomy, thyroidectomy, vocal cord polypectomy, hemiglossectomy, tracheal stenosis, neck dissection, and oral cavity lesions.
The company is expanding the Ceralas D Laser System's indications for use to include the following applications on intraoral and extraoral soft tissue (including marginal and interdental gingiva and epithelial lining of free gingiva): frenectomy; frenotomy; biopsy; operculectomy; implant recovery; gingivectomy; gingivoplasty; gingival troughing; crown lengthening; hemostasis of donor site; removal of granulation tissue; laser assisted flap surgery; debridement of diseased epithelial lining; incisions and draining of abscesses; tissue retraction for impressions: papillectomy: vestibuloplasty; excision of lesions; exposure of unerupted/partially erupted teeth: leukoplakia; removal of hyperplastic tissues; treatment of aphthous ulcers; and sulcular debridement (removal of diseased or inflamed soft tissue in the periodontal pocket).
As explained below, the Company's Ceralas D Laser System is substantially equivalent to the previously cleared Ceralas D Laser System (K951775, K964497), Premier Laser Systems' Aurora Diode Dental Laser (K954316, K974586). American Dental Technologies' Pulsemaster® 1000 ST Dental Diode Laser System (K972325), and American Dental Technologies' Pulsemaster® 1000 Nd:YAG Laser (K961269, K961136).
# Technological Characteristics and Substantial Equivalence
As stated above, there have been no significant changes to the Ceralas D Laser System since it was cleared by FDA. The Ceralas D Laser System is a complete self-contained compact surgical laser that utilizes gallium aluminum arsenide (GaAlAs) semiconductor diodes to generate near-infrared laser radiation. The laser employs a modular design comprised of: (1) a laser diode; (2) a cooling module containing the laser diode, thermoelectric coolers, heat sink fins and fans; (3) an optics module containing a beamsplitter for control of optical power; (4) front control and display panel; and (5) RFI-shielded, transformer power supply and control electronics. Interchangeable fiber optic delivery systems are coupled to the laser via an SMA 905 connector to deliver laser radiation to the target tissues. The diode laser is enclosed in a rugged, factory aligned, environmentally protective module.
The wavelength for the Ceralas D Laser System is 980 ± 30nm, and its laser aiming beam wavelength is 635nm+10nm. The power output ranges from 1-15 Watts. The delivery systems for the Ceralas D Laser System consist of an optical fiber fitted with an SMA 905 connector at the proximal end. The optical fiber is composed of quartz fiber core with a coaxially mounted protective sheath.
{2}------------------------------------------------
Moreover, the optical fiber delivery system has been previously cleared for dental use (K942182).
CeramOptec has made no significant changes to the hardware or software of the Ceralas D Laser since it was cleared by FDA. Likewise, CeramOptec has made no significant changes to its software development process since its previous 510(k) submission for the Ceralas D Laser System. Additionally, the software verification and validation were conducted in accordance with FDA's Guidance Document, "Reviewer Guidance For Computer Controlled Medical Devices Undergoing 510(k) Review."
The principal technological difference between the Ceralas Diode Laser and Premier Laser System's Aurora Diode Dental Laser is that the devices operate at different wavelengths. The Ceralas D Laser's wavelength is 980 ±30mm and the Aurora Diode Dental Laser's wavelength is 805-820mm. However, it is not believed that the difference between the devices' wavelength raise new questions of safety and effectiveness.
The Ceralas D Laser is also similar to American Dental Technologies' Pulsemaster® 1000 ST Diode Dental Laser. Both devices are similar in function and intended use. and are diode lasers which operate in a continuous or pulsed mode with wavelength ranges similar to the Premier Laser System's Aurora Diode Dental Laser. In summary, although there are minor differences between the Ceralas D Laser System and its predicate devices, these differences do not raise new questions of safety and efficacy.

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.
