### Technological Characteristics
LaserCap300, LaserCap224, LaserCap120, and LaserCap80 consist of red, visible light, diode lasers operating at 650 nanometers, configured within an outer helmet and protective inner liner, and configured for portable use with rechargeable battery and adapter. The devices only vary in number of lasers (300, 224, 120, and 80 diodes, respectively) and LaserCap300 has a small extension of the LaserCap housing perimeter where its additional laser diodes target peripheral hair-bearing areas of the scalp. 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 (1 short beep) or ended (one long beep). The portable systems are powered by rechargeable Li-lon battery cells assembled into a proprietary battery pack. Both the battery pack and charger are 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 device. The LaserCap300, LaserCap224, LaserCap120, and LaserCap80 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). This report validates the LaserCap300, LaserCap224, LaserCap120, and LaserCap80 the laser class of 3R which establishes the AEL (accessible emission limits) as 5 milliwatts maximum. With regard to all LaserCap models and predicate devices, there are no reported adverse events for this technology.
# Non-clinical Testing
The LaserCap family of devices were tested for standards conformance with IEC 60825-1, IEC 60601-1-11, IEC 60601- 1-2, and IEC 62133. The materials used in LaserCap construction that come in contact with the skin are the same biocompatible materials as the predicates.
# Substantial Equivalence
The LaserCap family of devices referenced in this application are the same technology used by the other Low Level Laser Therapy (LLT) devices cleared under device code OAP. The LaserCap300, LaserCap224, LaserCap120, and LaserCap80 are as safe and effective as the predicate devices. The sponsor is certain that the difference in number of diodes is of no consequence and does not affect safety or efficacy as there are a wide range of number of diodes in the predicate devices listed and in other LLLT devices cleared under device code OAP. All compliant LLLT systems which use red light diode lasers are classified as class 3R laser systems according to the IEC standard for allowable emission levels, which is a recognized standard by the FDA as well, and the adverse event profile is the same.

* LaserCap224 and LaserCap80 are legally marketed devices under the names LCPRO with 224 laser diodes and LCELITE with 80 laser diodes, respectively; K150613. Names changed in this submission for naming consistency with the proposed expanded family of LaserCap devices.
Based on technology, therapy outcome, similar design, wavelength choice, and treatment session time (all substantially equivalent), the expansion of the use for males from one device to
{6}------------------------------------------------
its equivalent is reasonable and consistent with the known uses attributed to LLLT devices in general, and over a wide range in number of laser diodes, between devices. The predicate Capillus family of devices has been cleared for use in both men and women and there have been no reported safety issues with any LLLT device to date, with many indicated for use in both men and women. It is therefore established that there is no difference between the devices, the regimens, or the technology; and the number of diodes does not adversely affect the safety of the devices. Thus, the sponsor maintains that the indications for use for the submitted LaserCap devices should apply as stated: The LaserCap224, LaserCap224, LaserCap120, and LaserCap80 are indicated to promote hair growth in males with androgenic alopecia who have Norwood Hamilton classifications of Ila to V or females with androgenic alopecia who have Ludwig-Savin Classifications of I – II and both with Fitzpatrick Skin Phototypes I to IV. For these reasons, the LaserCap300, LaserCap224, LaserCap120, and LaserCap80 satisfy the FDA's substantial equivalence with respect to intended use, technological and design characteristics. With reference to all devices cleared through the OAP device classification, the sponsor respectfully proposes that the FDA has acknowledged that Low-Level Laser Light Therapy is a viable modality for treating androgenetic alopecia in both genders and that the red light lasers in class 3R, used in the LaserCap devices referenced in this application are substantially equivalent to the predicates. Additionally, no new safety or efficacy concerns are raised due to the minor differences present between devices.
In summary, the LaserCap family of legally marketed devices and proposed new devices are essentially identical to the Capillus family of legally marketed devices, except for some small variations in number of laser diodes in the devices. And varying the number of laser diodes in these devices should not change safety or efficacy of these devices, as evidenced by predicate devices Capillus82 and Capillus202 which were new devices cleared by Special 510 (k) K151516 and K153618, respectively, using a 272 diode laser cap device as the predicate, and by reference devices Hairmax Lasercomb41 and Lasercomb82 for use in men and women (K142573) which were cleared using a 9 laser diode lasercomb as the predicate device.
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.
