## Device Description
The Dornier Medilas H Solvo 35 Laser is a solid-state Holmium YAG Laser. The laser emits laser radiation in the invisible wavelength range of 2080 nm in either a continuous-wave or pulsed mode, which is absorbed primarily by water, with an average penetration depth of approximately 400 um (0.4mm). Due to the application-dependent optimization of the pulse time of 350 microseconds, the Solvo can be used in various medical applications including breaking up stones, cutting tissue, tissue ablation, coaqulation and vaporization.
The laser is microprocessor-controlled utilizing a watchdog-monitored microprocessor and operates with an internal cooling system and a heat exchanger. The bottom of the housing serves as a tank for cooling water and, at the same time, a base for the laser unit. A cooling circuit conducts away heat that is generated by the laser pump lamp. Water heated by the laser pump is conducted out of the cavity and into the stainless steel cooler. Following cooling, it is returned to the tanks.
A graphic control panel regulates and displays the operating parameters, application modes, time functions, system status and messages to the user. The control panel consists of a display with integrated touch screen panel applications to control the functions of the laser. There is a wireless remote display panel available as well that allows the user to see the control panel information without being in front of the unit.
## Summary of Technological Characteristics
The Dornier Medilas H Solvo 35 has the same technological characteristics as the Dornier H30 Solvo Laser to which it is a modification. Both lasers are solid state Holmium HO:YAG lasers that operate at a wavelength of 2080 nm. They both operate using the same basic hardware and software platforms, as well as utilize identical laser delivery systems (fiber optic laser cables with SMA 905 connectors).
The primary difference in technical performance characteristics is the available maximum power and frequency and the option to use pre-set laser settings The Dornier Medilas H Solvo 35 has a maximum power of 35W while the Dornier H30 Solvo Laser has a maximum power of 30W. This difference in maximum power does not increase the laser energy range, which is 200- 3500 mJ. The pulse frequency range for the Dornier Medilas H Solvo 35 laser is 3-25 Hz while the range for the predicate Laser is 3-20Hz. This higher maximum power output and frequency is within the range of other cleared Holmium Lasers (Quanta Litho Laser. K163009). The use of a 35W laser for the stated indications is also well established by other cleared lasers. The pre-set laser settings are for user convenience.
{5}------------------------------------------------
The other minor differences between the Dornier Medilas H Solvo 35 and the cleared device are the addition of a remote output display and other minor modifications to support the above noted changes. These include:
- Updated CPU board
- Modified cooling water circuit/pumps.
### Performance Data
While no performance standards have been established for Holmium lasers under Section 514 of the Federal Food, Drug, and Cosmetic Act, the Dornier Medilas H Solvo 35 is in compliance with class IV performance standards for light emitting products promulgated under the Radiation Control for Health and Safety Act of 1968. The laser complies with the applicable requirements of the following voluntary standards:
- . IEC60601-1:2005 Medical electrical equipment - Part 1: General requirements for basic safety and essential performance
- . IEC 60601-1-2:2014 Medical electrical equipment - Part 1-2: General requirements for basic safety and essential performance - Collateral standard: Electromagnetic compatibility -Requirements and tests
- . IEC 60601-2-22:2007 Medical electrical equipment - Part 2-22: Particular requirements for basic safety and essential performance of surgical, cosmetic, therapeutic and diagnostic laser equipment
- IEC 60825-1: 2014 Safety of laser products Part 1: Equipment classification, and . requirements [Including: Technical Corrigendum 1 (2008), Interpretation Sheet 1 (2007), Interpretation Sheet 2 (2007)]
- . IEC 60601-1-6:2010 Medical electrical equipment Part 1-6 General requirements for safety -Collateral Standard: Usability
- . Risk analysis activities, in compliance with the requirements of ISO 14971: 2007 Medical devices - Application of Risk Management to Medical Devices
In addition, software verification and validation in compliance with FDA Guidance for the Premarket Submissions for Software Contained in Medical Devices was performed.
These tests verified that the subject laser performs according to its specifications.
#### Substantial Equivalence
From a clinical perspective and comparing design specifications, the Dornier Medilas H Solvo 35 and the predicate devices are substantially equivalent and have the same intended use. Based on the technological characteristics, design and overall performance of the devices, Dornier MedTech America believes that no significant differences exist between the Dornier Medilas H Solvo 35 and Dornier's Medilas H30 Solvo Laser (K122159).
{6}------------------------------------------------
The minor differences do not raise any concerns regarding the overall safety or effectiveness of the subject device compared to the predicate device. Thus, the Dornier Medilas H Solvo 35 is substantially equivalent to its predicate device.
## Conclusion
The Dornier Medilas H Solvo 35 Laser is as safe and effective as the Dornier Solvo Laser. The Dornier Medilas H Solvo 35 has the same intended uses and similar indications, technological characteristics, and principles of operation as its predicate device. In addition, the minor technological differences between the Dornier Medilas H Solvo 35 and its predicate devices raise no new or different issues of safety or effectiveness. Thus, the Dornier Medilas H Solvo 35 is substantially equivalent.
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.
