Software verification testing performed for collision protection and hand controller function. Engineering analysis confirmed compatibility of additional ultrasound systems.
Indicated for fragmentation of urinary tract stones (renal calyceal, renal pelvic, and upper ureteral stones) in adult patients.
Regulatory Classification
Identification
An extracorporeal shock wave lithotripter is a device that focuses ultrasonic shock waves into the body to noninvasively fragment urinary calculi within the kidney or ureter. The primary components of the device are a shock wave generator, high voltage generator, control console, imaging/localization system, and patient table. Prior to treatment, the urinary stone is targeted using either an integral or stand-alone localization/imaging system. Shock waves are typically generated using electrostatic spark discharge (spark gap), electromagnetically repelled membranes, or piezoelectric crystal arrays, and focused onto the stone with either a specially designed reflector, dish, or acoustic lens. The shock waves are created under water within the shock wave generator, and are transferred to the patient's body using an appropriate acoustic interface. After the stone has been fragmented by the focused shock waves, the fragments pass out of the body with the patient's urine.

#### Common or Usual Name
Shock Wave Lithotripter
#### Classification Name
According to 21 C.F.R. § 876.5990, FDA has classified extracorporeal shock wave lithotripters as Class II devices with special controls. The Product Code for these lithotripters is LNS.
#### Predicate Device
Dornier Delta III Lithotripter (K170122)
#### Purpose of the 510(k) Notice
The Delta III Lithotripter that is the subject of this submission is a modification to the Dornier Delta III Lithotripter (K170122) to include the following minor changes:
- The UIMS cart wheels were required to be replaced as a result of their obsolescence, O
- Several electronic components were required to be modified or upgraded as O a result of additional IEC electrical testing,
- In order to affix the CE Mark, the power rating label of the Delta III X-ray device had o to be changed to reflect the effective power as measured instead of the actual power input level.
{4}------------------------------------------------
- A modification to the collision system was required due to instances when the o restoring force relating to the collision system is too low, the collision system output signal remains in "collision mode" even though the collision situation has been corrected.
- O For user convenience and preference, a software change was made that allows the user to utilize fluoroscopy without significant delay directly after a snap shot is taken,
- Additional Ultrasound base units are now being offered to use with the identical o ultrasound transducer, and
- A easier applied inner coating lining of the hand controller has been implemented. o
The modified Delta III has the same intended use, technological characteristics, and principles of operation as the predicate device. The difference between the modified Delta III and the predicate device does not raise any new or different questions of performance, safety or effectiveness. Thus, Dornier believes that the modified Delta III is substantially equivalent.
# Intended Use/Indications for Use
The Delta III Lithotripter is indicated for the fragmentation of urinary tract stones, i.e., renal calyceal stones, renal pelvic stones, and upper ureteral stones.
# Device Description
The Delta III Lithotripter is a modular urological work station designed for extracorporeal shock wave lithotripsy ("ESWL") and for diagnostic and therapeutic procedures usual in urology.
The Delta III is composed of the following modules:
- . Basic Unit with integrated X-ray C-arm and Therapy Arm with camera for Shockwave Treatment;
- Patient Table;
- . Control Desk - Image Processing.
The basic unit contains the power supplies, control unit, power electronics for motor drives, components for shockwave generation, and an integrated Therapy C-arm and an X-Ray C-Arm. The housing can be positioned with its back close to the room wall and has wide side doors for easy service.
The therapy and X-Ray C-arm house the shock wave source ("EMSE") and the complete Xray unit. The X-ray unit consists of the X-ray generator, the X-ray tube, an image receptor system, and a high resolution imaging chain. This provides the imaging to perform the procedures. The C-arms allow for a wide range of movement to facilitate performing urological procedures. The shock wave circuit supplies the shock wave energy needed for the treatment of kidney stones.
The Delta III's urological patient table provides longitudinal, lateral and vertical travel range to allow easy positioning of the stone in the shock wave focus for lithotripsy and urological
{5}------------------------------------------------
procedures.
The image processing system (UIMS) with DICOM 3 capability supports PACS connection and offers complete X-ray control and image handling.
All of the characteristics described above of the Delta III subject to this submission are identical to the predicate device.
# Technological Characteristics
As described in the section above, the Delta III device has the same technical characteristics as the predicate. This includes function and operation of the three main modules that comprise the system, the Basic Unit with integrated X-ray C-arm and Therapy Arm with camera for Shockwave Treatment, the Patient Table and the Control Desk and Image Processing ability. The minor changes that are associated with this submission do not change the essential function and use of the Delta III as compared to the predicate.
# Performance Data
The company has complied with all of the requirements described in FDA's Guidance for the Content of Premarket Notifications (510(k)s) for Extracorporeal Shock Wave Lithotripters Indicated for the Fragmentation of Kidnev and Ureteral Calculi.
The device is in compliance with the following standards:
- IEC 60601-1:2005,Electrical safety of medical devices;
- . IEC 60601-1-2:2007, Electomagnetic compatibility:
- IEC 60601-1-3: 2008, Radiation protection in diagnostic X-ray equipment; ●
- IEC 60601-2-36: 1997, Safety of equipment for extracorporeally induced lithotripsy; ●
- . IEC 61846, Ultrasonics - pressure pulse lithotripters characteristics of fields;
- IEC 60601-2-54, Medical electrical equipment particular requirements for the . basic safety and essential performance of x-ray equipment; and
- . Usability: IEC 62366:2007, Application of usability engineering to medical devices.
In summary, during the verification testing, the electrical safety of the system and the electromagnetic compatibility were fully addressed by demonstrating compliance with the applicable standards. In addition, appropriate software verification testing to sections of IEC 60601-1 for wheel performance and collision protection, and verification of hand controller function testing were also performed to address the modifications made that are subject to this submission.
Also, an engineering analysis concluded that the prior ultrasound localization accuracy testing supported the compatibility of the additional ultrasound systems that were added.
There were no unanticipated new risks identified
# Conclusions
The Delta III is as safe and effective as the cited predicate device. The Delta III has the same intended uses and indications, technological characteristics, and principles of
{6}------------------------------------------------
operation as its predicate device. The minor differences do not alter the intended the use of the device and do not affect its safety and effectiveness when used as labeled. In addition, the minor technological differences between the Delta III and its predicate devices raise no new or different questions of safety or effectiveness. Design controls demonstrate that the Delta III is as safe and effective as the predicate device. Thus, the Delta III is substantially equivalent.

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.
