Indications for Use
The laser is used to create laser energy for the destruction of calculi and/or for soft tissue treatments such as the cutting of tissue and the opening of stenosis and strictures during endoscopic urological applications.
Device Story
Calculase II is a desktop Ho-YAG laser system emitting 2080nm mid-infrared energy; used in urological endoscopic procedures. System comprises desktop unit with control panel, LED displays, and 1-pedal footswitch. Operator inserts flexible laser fiber through endoscope (flexible, semi-rigid, or rigid) via urethra or percutaneously to target site. Laser energy (500-2000mJ, 4-15Hz, max 20W) fragments/vaporizes calculi or ablates soft tissue. Footswitch activation allows hands-free operation. Concentrated beam enables thermal effect on target while surrounding tissue cools between pulses. Device intended for use by clinicians in treatment rooms. Output allows precise stone fragmentation and tissue ablation, potentially reducing patient recovery time and invasiveness of urological procedures.
Clinical Evidence
No clinical data. Bench testing only, including performance verification and validation of pulse duration, pulse energy, and max output. Compliance with IEC 60601-1, IEC 60601-1-2, IEC 60601-2-22, and IEC 60825-1.
Indicated for destruction of calculi and soft tissue treatments (cutting tissue, opening stenosis/strictures) during endoscopic urological applications.

| Device Identification: | Trade Name: Calculase II<br>Common Name: Powered Laser Surgical Instrument<br>Classification Name: Powered Laser Surgical Instrument |
| Product Code: | GEX |
| Regulation: | CFR 878.4810 |
| Predicate Device(s): | AURIGA QI (K121570) |
| Device Description: | The KARL STORZ Calculase II is a Ho-YAG desktop laser<br>that emits a mid-infrared beam at the wavelength of 2080nm<br>with pulse energy of 500-2000mJ and pulse frequency of 4 –<br>15Hz. The laser energy is transmitted into the tissue via an<br>optical fiber, with the maximum limit of the laser energy set at<br>20W.<br><br>The laser energy generated by Calculase II enables the optimal<br>lithotripsy of all calculus compositions in the human body and<br>soft tissue treatment such as the ablation of strictures and<br>stenosis, for example. |
| | Calculase II is a desktop unit designed to be mobile so that it<br>can be easily transported and placed on top of a desk or cart<br>and positioned within the treatment room by using special,<br>retractable handles located on the both sides of the desktop<br>units. All controls and displays required for operating the unit<br>(On/off switching key, fiber connection port, power setting.<br>etc.) are located on the front of the device in a user-friendly<br>control panel and easy-to-read LED displays, which make the<br>unit safe and easy to operate by the users. The 1-pedal<br>footswitch allows the users to release the laser to the intended<br>area during use. |
| | The Calculase II Holmium Laser system uses a flexible laser<br>fiber, inserted into an endoscope (flexible, semi-rigid and rigid)<br>through the urethra or percutaneously to fragment and vaporize<br>the calculi stone located in the bladder, urethra, or kidney.<br>With the proper energy level setting, it can also perform soft<br>tissue treatments such as ablation of strictures and stenosis.<br>For lithotripsy, proper energy level should be set depending on<br>the fiber diameter, hardness of stone, and location of the stone. |
| | The laser emission is activated by a footswitch pedal, which<br>allows the operator to be "hands-free" for specific target<br>fragmentation. With the fiber placed lightly against the stone<br>or soft tissue in the contact procedure, pulses of energy are<br>used to fragment and vaporize the stone or ablate strictures and<br>stenosis. |
| | As the laser beam is concentrated on the target area, the<br>surrounding tissue can relax, cool and dissipate the heat in<br>between the short bursts. This way the target tissue sustains<br>cumulative thermal effect with maximum protection of the<br>surrounding area. |
| Indications For Use: | The laser is used to create laser energy for the destruction of<br>calculi and/or for soft tissue treatments such as the cutting of<br>tissue and the opening of stenosis and strictures during<br>endoscopic urological applications |
| Technological<br>Characteristics: | The predicate and subject devices are both Holmium Laser<br>System that emit laser energy at the wavelength of 2080nm.<br>However, due to the limitation of the indications of the subject<br>device compared to the predicate, they have minor differences<br>in the technological characteristics. These differences are: |
| | The subject device has a maximum energy output as<br>● |
| | 20W, whereas the predicate has the maximum<br>energy output as 30W; a difference of 10W in<br>maximum energy.<br>The range for pulse duration for the subject device<br>is 100 – 500 μs, whereas the predicate device's<br>range for pulse duration is 200 – 500 μs; a<br>difference of 100µs in the lower limit for pulse<br>duration. The ranges for the frequency and pulse energy for<br>the subject device are 4 – 15 Hz and 500 – 2000 mJ,<br>respectively, whereas the predicate device has the<br>ranges for the frequency and pulse energy are 4 – 20<br>Hz and 200 – 4000 mJ, respectively; a difference of<br>5 Hz in the upper limit of the frequency range, 300<br>mJ in the lower limit and 2000 mJ in the upper limit<br>of the pulse energy's range. The bench test data for the Calculase II Holmium Laser System<br>demonstrates that the design characteristics used as the basis<br>for the comparison have been met. The results show that the<br>subject device has met all its specifications. The performance<br>validation test report, System Test Record, is provided in<br>section 021_Performance Testing of this submission.<br>Combining the minor difference in specifications with the<br>limited indication of use in the Calculase II compared to the<br>predicate device, Auriga QI, Calculase II does not raise new<br>issues of safety and effectiveness and the devices are<br>substantially equivalent for urological application. |
| Non-Clinical<br>Performance Data: | Calculase II is tested according to the following standard:<br>IEC 60601-1 IEC 60601-1-2 IEC 60601-2-22 IEC 60825-1 Additional bench testing for performance verification and<br>validation purposes:<br>Max Output Pulse Duration |
| | Pulse Energy |
| | The bench testing performed verified and validated that the<br>Calculase II has met all its design specification and is<br>substantially equivalent to the predicate device, AURIGA QI,<br>for urological procedures. |
| Clinical<br>Performance Data: | No clinical information is required for this submission |
| Conclusion: | The Karl Storz's Calculase II is substantially equivalent to its<br>predicate devices. The non-clinical testing demonstrates that<br>the device is as safe and effective as the legally marketed<br>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.
