The Pajunk StimuLong Tsui-Method Sets are intended for delivery of continuous conduction anesthesia to epidural space as well as optional to peripheral nerves and plexus. The catheter has to be removed or replaced after 72 hours. Continuous delivery is accomplished using the conduction catheter. To assist the physician to precisely and safe pinpoint the area of application in peripheral use an electrical stimulus can be applied to the conduction needle. After placement of the conduction catheter in epidural space or peripheral an electrical stimulus can be applied to its tip via the catheter adapter. The set is to be used with adults and in pediatrics.
Device Story
Kit for continuous epidural or peripheral nerve anesthesia; includes coated Tuohy cannula, Polyamide indwelling catheter, stimulation adapter, cables, injection valve/hose, filter, and fixation devices. Physician inserts cannula to place catheter; electrical stimulus applied via cannula or catheter tip to verify target nerve/plexus location before anesthetic delivery.

### Device Description
Pajunk GmbH Medizintechnologie is submitting this 510(k) for the Pajunk StimuLong Tsui Method Set. The Tsui-Test is a well known technique in epidural anesthesia. It combines the advantages of epidural anestesia and stimulation via catheter in order to verify the area anesthesia is applied to. The Tsui test makes epidural anesthesia much more safe and effective as demonstrated and proven in several studies and articles published since the 1990 % (see section 20 of this submission.
Physicians until now had to combine different devices in order to get a "self-made set acc. Tsui". Dr. Tsui combined Pajunks StimuLong set and technique deared for perifical use and Prayinks Epilong set and technique for epidural use to have a striking safe and effective alternative to "selfmade in-house devices".
The devices for epidural Anesthesia (EpiLong) and peripheral Anesthesia employing stimulation via catheter (StimuLong) are already cleared for market seperately without claiming specific patient populations. The basis of this submission in the indications for use of this two cleared device: peripheral and epidural stimulation guided anesthesia.
The components which are part of the subject device kit have already gained market clearance. They are combined under a new indication on customers demands.
The predicate devices are Pajunks own products cleared for a non specified population, i.e. for use with adult patients. In order to demonstrate safety and effectiveness Pajunk provides clinical lieterature from Dr. Tsui as well as a clinical evaluation.
Pajunks StimuLong Tsul Method Set are single use, sterile, non-pyrogenic and latex free medical device kits.
They are intended for continuous peripheral or epidural anesthesia delivery using the Polyamide indwelling catheter. The catheter has to be removed or replaced after 72 hours. An electrical stimulus may be applied via catheter in order to precisely identify the area anesthesia is intended to be applied to.
## Predicate Devices
The devices Pajunk claims substantial equivalence with are Pajunks StimuLong Set and UP cannulas cleared under K000722, K033018, K043130, K 040965 and Pajunks EpiLong Set cleared under K060311.
The indications of StimuLong and EpiLong are already cleared for market.
Because the devices are technical cleared this submission concentrates on the clinical discussion of the combination of advantages of epidentiation of the cirinear
The detailed disoussion of substantial eqivalence can be found in Section 12 of this submission. Because there is no change in technology or material the focus is set on the clinical liferature review in section 10 of this submission.
## Sterilization
### Sterilization method: EtO
The contract sterilizer and the sterilizing process are identical to the ones used for all of Pajunks devices provided sterile, essee continue production devices cleared for the US market in several Premarket Notification submissions.
By annual validation and quarterly verification as well as by shelflife testing the sterilization procedure is claimed to be safe and effective for several years now.

## Technology Characteristics:
The Pajunks StimuLong Tsui Method Set provides a coated Tuohy cannula, a StimuLong catheter, StimuLong adaptor, valve, adaptor cables, injection hose, filter, LOR-syringe, catheter fixation device, FixoLong and tightning adaptors. The coating on the cannula is laqueur or NanoLine coating, which has been cleared in K053283.
The catheter comes with a catheter container, steel stylett and introductory aid for better handling and shape security. The catheter is closed at tip and equipped with three lateral holes, optional with open tip, an integrated spiral (for enhanced stability) and a stylett. There is no change in components compared to the StimuLong and EpiLong set already cleared for market.
All components are available seperately. Within the indications for use and the components cleared for market the StimuLong Tsui method set is customizable.
#### Conclusion:
The comparison between the predicate devices and the proposed devices in section 12 of this submission demonstrates that the proposed devices are at least as safe and effective as, and substantially equivalent to the predicate devices. A rationale for the method is included this sumbission.

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.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
