The Capillus laser domes 82, 202, 272 Pro, 272 OfficePro, 302, 312, and 352, are intended to treat Androgenetic Alopecia and promote hair growth in males who have Norwood -Hamilton Classifications of IIa to V patterns of hair loss and to treat Androgenetic Alopecia and promote hair growth in females who have Ludwig (Savin) Scale I-1 to I-4, II-1, II-2, or frontal; both with Fitzpatrick Skin Types I to IV.
{4}------------------------------------------------
### Technological Characteristics
The Capillus272 Pro and Capillus272 OfficePro both consist of 272 red, visible light, diode lasers operating at 650 nanometers, configured within an outer helmet and protective inner, and configured for portable use with rechargeable battery and adapter (Capillus272 Pro) and salon/spa use (Capillus272 OfficePro). The Capillus82, Capillus202, Capillus302, Capillus312, and Capillus352 are exactly the same as the Capillus272 Pro with the exception of the number of diodes which are respective of model (e.g. 82 diodes in Capillus82).
As stated in prior submissions, the devices emit an audible tone at the beginning and end of a therapy session, indicating that therapy has begun (2 short beeps) or ended (one long beep). The portable systems are powered by rechargeable Li-Ion battery cells assembled into a proprietary battery pack. Both the battery are fully compliant to recognized, international standards. The OfficePro is directly powered by the DC charger, which is fully compliant to recognized, international standards.
### Performance Data:
Performance testing was conducted to confirm compliance to design specifications; all functions have been verified to operate as designed. All acceptance criteria were met by the devices. The Capillus202, Capillus272 Pro, 272 OfficePro, Capillus302, Capillus312, and Capillus352 conform to the standard IEC-60825-2007-03. This IEC standard is a recognized and accepted standard by the FDA. The guidance document for this accepted standard is found in the Federal register, July 26, 2001 (volume 66, Number 144) [page 39049 39050]. This report validates for the Capillus82, Capillus202, Capillus272 Pro, 272 OfficePro, Capillus312, and Capillus352 the laser class of 3R which establishes the AEL (accessible emission limits) as 5 milliWatts maximum. The charger conforms to IEC 61959.
The data presented in this submission is restricted to self-selection and usability to include comprehension of user instructions, warnings, and precautions. The results of a presubmission request (Q160385) verified the objectives that must be fulfilled for the Capillus family of devices to be classified for over-the-counter (OTC) sale. One of the responses for the Q-submission indicated that a minimum of an 80% success rate must be achieved for the intended use of OTC to be granted. The testing was administered to 55 adult subjects of any age (>18), educational background, race, disease status present or pre-education about the testing to be performed. This was designed to provide for the broadest test criteria without any bias being imposed, thereby assessing the real-world capability of the average adult, "retail customer" who might wish to purchase a device without the benefit of a physician or other qualified health care provide counsel as is the case with prescription devices. The study was conducted in two (2) parts specifically intended to demonstrate that the device is appropriate for consumer use by lay persons (see data and report in Section 13). The first part addressed self-selection (box labeling), while the second part addressed the content of the user manual including warnings and precautions. The Capillus usability test demonstrated a pass rate of 94.6% (self-selection) and 90.9% pass rate for user instruction questionnaire, satisfying the FDA's requirements for clearance (sale) as Over-the-Counter Intended Use.
Just as for Capillus272 Pro (K143199) and reference devices, there are no reported adverse events for this technology.
{5}------------------------------------------------
### Substantial Equivalence
The requirements set for substantial equivalence in the traditional sense, do not have applicability in this process as the purpose of this submission is expansion of indications for use to include OTC sale capability. However, The Hairmax Lasercomb and iGrow Hair Growth System (predicate devices) have been cleared with the Intended Use of Over-the-Counter, and the Capillus devices can demonstrate the minimum pass-rate for usability by lay persons. The Capillus devices utilize the same technology and share the same risk profile as the predicates. The Capillus family of devices referenced in this application are the same technology used by all LLLT devices cleared under device code OAP. The Capillus272 Pro, Capillus272 OfficePro, Capillus202, Capillus202, Capillus302, Capillus312 and Capillus352 are as safe and effective as the predicate devices, as well as other reference devices in its class.

For these reasons, the Capillus family of laser domes satisfy the FDA's substantial equivalence requirements with respect to risk profile, intended use, and technological and design characteristics. Additionally, no new safety or efficacy concerns are raised due to the minor differences present between 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.
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.
