#### Intended Use/ Indications for Use:
The LightSheer pulsed diode array laser systems are indicated for use in surgical, aesthetic, and cosmetic applications in the medical specialties of general and plastic surgery, and dermatology. The LightSheer pulsed diode array laser systems are intended for use on all skin types (Fitzpatrick skin types I – VI), including tanned skin.
The LightSheer Desire Light Laser System with LightSheer ET/XC Laser Handpiece is indicated for the treatment of vascular lesions, including angiomas, telangiectasia and other benign vascular lesions, the treatment of Pseudofolliculitis Barbae (PFB). The LightSheer Desire Light Laser System with LightSheer ET/XC Laser Handpiece is also indicated for hair removal, permanent hair reduction* and the treatment of benign pigmented lesions and leg veins.
* Note: Permanent hair reduction is defined as the long-term, stable reduction in the number of hairs regrowing when measured at 6, 9, and 12 months after the completion of a treatment regime.
#### Modified Device Description:
The modified LightSheer Desire Light Laser System is a non-invasive aesthetic laser system that delivers pulsed infrared laser light with a wavelength ranging from 790-830 nm (805 nm nominal). The system consists of a laser console and two optional handpieces, ET or XC, which can be connected to the console, one at a time, via a universal plug-in connector and an umbilical cable.
The ET handpiece; delivers laser energy through a 9mm tip up to 81 J maximum. The settings for this handpiece are selectable pulse duration from 5-400 ms, selectable fluency from 10-100 J/cm² and a pulse repetition rate up to 3 Hz maximum. The XC handpiece; delivers laser energy through a 12mm x 12mm tip up to 58 J maximum. The settings for this handpiece are selectable pulse duration from 5-400 ms, selectable fluency from 10-40 J/cm² and a pulse repetition rate up to 3 Hz maximum
The laser system delivers pulsed infrared laser light from the diode array in the ET or XC handpiece to the treatment area. In standard use, the handpiece is pressed against the patient's skin and a pulse of light is delivered. To initiate energy output, the system requires redundant activation of the handpiece enable button and the handpiece trigger button while the system is in the Ready mode.
The ET and XC handpieces include a chilled sapphire tip that is water-cooled to provide active skin cooling. The physician is able to control the settings of laser energy from the LCD display on the main console.

#### Substantial Equivalence
The intended use and indications for use of the LightSheer Desire Light Laser System are identical to the intended use and indications for use of its predicate device. In addition, the same technological characteristics and principles of operation apply for both systems. The modifications introduced to the subject LightSheer Desire Light Laser System as compared to the predicate system are designed and intended mainly for updating the system industrial design to form a table top console and increased user convenience.
Performance testing was conducted in order to demonstrate the performance of the LightSheer Desire Light Laser System and its substantial equivalence, with respect to the safety and effectiveness, to the cleared predicate system. The following activities were performed:
- Risk analysis activities in compliance with the requirements of ISO 14971.
- . Electrical and laser safety and electromagnetic compatibility testing as required to conform to with the following performance standards:
- । EN 60601-1-2: Medical electrical equipment - Part 1-2: General requirements for basic safety and essential performance- Collateral standard: Electromagnetic compatibility- requirements and tests.
- EN 60601-1: Medical electrical equipment Part 1: General requirements for । basic safety and essential performance.
- EN 60601-2-22: Medical electrical equipment- part 2: particular requirements for । the safety of diagnostic and therapeutic laser equipment.
- । EN 60825-1: Safety of laser products-Part 1: Equipment classification and requirements.
- Software verification and validation testing.
- . Environmental testing demonstrating the ability of the subject system to withstand variant operation, storage and transportation conditions.
- . System testing (e.g. handpieces use and authorization, treatment parameters, energy measurements, handpiece replacement, handpiece cooling, safety controls).
Test results indicated that the subject LightSheer Desire Light Laser System performs in accordance with its requirements and specifications, in similarity to its predicate device. Consequently, the LightSheer Desire Light Laser System was found to perform as well as its predicate, to be as safe and effective for its intended use as its predicate, and is substantially equivalent to its predicate device without raising any new safety and/or effectiveness issues.

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.
