#### Device Description
The ERBEJET® 2 System includes the Hydrosurgical unit model ERBEJET® 2, the pump cartridge plus, instruments (applicators and ERBEJET probe), an optional suction model ESM 2 with accessories and a one- or two-pedal footswitch. Together these components form the ERBEJET® 2 System. The system provides an adjustable high-pressure water jet (pressurized normal saline solution) intended for tissue-selective hydrodissection and needle-free injection in endoscopic and/or surgical interventions. The ERBEJET® 2 unit together with its accessories is an active invasive surgical system. The sterile normal saline solution is the "medium" which is projected under pressure through a nozzle of the connected instrument to achieve the desired tissue effect.
{4}------------------------------------------------
### Hydrosurgical Unit
The ERBEJET® 2 Hydrosurgical Unit is a standalone Unit that can be mounted / secured to a cart. It has a monochromatic display (blue/white) that provides the user with settings and operational information. The display is surrounded by buttons allowing the user to control the unit (e.g., set the effect, select a program). In order to pressurize and deliver the medium to a connected Applicator, a pump cartridge (attached to the medium) must be connected to the ERBEJET 2. Activation of the Unit and subsequent delivery of the medium is possible with a connected footswitch. The pressure ranges from 1 to 80 bar (+/-20%) (14.5 - 1160.3psi (+/-20%)) which corresponds to a volume flow of 3.5 – 55 ml/min (± 10% or ± 1 ml, depending on which value is larger).
#### Applicators and ERBEJET probe
The applicators and ERBEJET probe are sterile, single-use instruments which are available in various length and diameters as well as with or without an additional suction line.
#### Accessories
## Pump cartridge plus
The single use sterile pump cartridge is inserted into the ERBEJET® 2 unit. It has a chamber with two pistons and is the conduit for the medium which is connected to the cartridge via luer lock to be pressurized. The pressure is mechanically provided by the ERBEJET® 2 unit by engaging the pistons of the pump cartridge.
#### Footswitch
A one-pedal and two-pedal footswitch have been designed for the ERBEJET® 2. The footswitches are used to activate the Unit.
#### Suction module and accessories
The optional suction module ESM 2 can be integrated into the ERBEJET 2 System. Various accessories (i.e. filter, suction hose, etc.) connect the ESM 2 to a suction container and to the applicator to aspirate fluids from the surgical site.
#### Other accessories
Accessories that may be used for the mounting of the unit.

### Indications for Use
#### ERBEJET® 2
The Erbe hydrosurgical unit ERBEJET 2 with instruments and accessories is intended to pressurize a medium to perform needle-free injection and tissue-selective hydrodissection of soft tissue. The Erbe hydrosurgical unit ERBEJET 2 with instruments and accessories is used in endoscopic and surgical procedures.
#### Applicators and ERBEJET probe
20150-220: The ERBEJET probe is intended for dissection (tissue-selective hydrodissection) including separation of soft tissue in endoscopic interventions. The ERBEJET probe can be used for needle-free injection including lifting of mucosal lesions by injection into the submucosa.
20150-225: The applicator is intended for dissection (tissue-selective hydrodissection) including separation of soft tissue in open surgery.
20150-226: The applicator is intended for dissection (tissue-selective hydrodissection) including separation of soft tissue in minimal invasive surgery. The applicator can be used for needle-free injection including lifting of mucosal lesions by injection into the submucosa.
20150-230, 20150-231, 20150-239: The applicators with suction are intended for dissection (tissue-selective hydrodissection) including separation of soft tissue in open surgery. The applicators with suction can be used as well for suction when connected to an external suction module e.g. Erbe ESM 2.
20150-238: The applicator with suction is intended for dissection (tissue-selective hydrodissection) including separation of soft tissue in minimal invasive surgery. The applicator with suction can be used as well for suction when connected to an external suction module e.g. Erbe ESM 2.
Compared to the legally marketed predicate devices, the subject device has a reworded indications for use statement. In general, Erbe would like to have a more encompassing indications for use (intended use) for the unit, and have more specifics as to applications in the instrument's indications for use (intended use). Erbe changed the term injection to needle-free injection for clarification since the instruments don´t have a needle. The phrase dissection of tissue was changed to tissue-selective hydrodissection since this is the commonly used clinical term which is used by physicians and supported by peer-reviewed literature. Furthermore, the term "cutting" has been omitted for clarification purposes since dissection/hydrodissection is a more accurate term for water jet application (Note: From a clinicians view point, "cutting" is a term in electrosurgery that is associated with the delivery of monopolar or bipolar energy or a term in general surgery of a mechanical nature, e.g. scalpel). Additionally, the indications for use of the associated instruments (i.e. applicators and ERBEJET probe) will then provide further specifics for optimal use in a clinical setting in accordance with the proposed intended use of the unit. Therefore, the phrases "lifting mucosal lesions by injection into the submucosa" which is associated with the function "needle-free injection" and "separation of soft tissue"
{6}------------------------------------------------
#### Erbe Elektromedizin GmbH K231023 - Traditional 510(k) for ERBEJET® 2 System
which is associated with the function "tissue-selective hydrodissection" are additionally being used for the indications for use statement of the applicators and ERBEJET probe as applicable. Taken together, the indications for use statement was reworded for clarity in order to better describe the actual function without changing the original meaning. The intended use is substantially equivalent compared the predicate device.
### Comparison of Technological Characteristics with the Predicate Device
Compared to the legally marketed predicate devices the subject device has additional applicators and the ERBEJET probe. The additional instruments have partially different materials and dimensions. However, the energy source and technological principle is the same. Since the ERBEJET® 2 system is a volume-controlled system, the flow rate is always the same and independent of the instruments design. The only performance parameter that is influenced by the instrument design is the dynamic pressure which depends on the nozzle geometry. Since all proposed applicators and the ERBEJET probe have the same nozzle geometry as the predicate devices, the generated dynamic pressure, and hence, the performance is also the same.
Another change is related to the pump cartridge. Compared to the legally marketed predicate device, the subject device has a new pump cartridge with optimized design modifications were made to improve the insertion behavior into the unit, to enable the change of instruments during surgery and to improve the priming process. Furthermore, the proposed pump cartridge also has slightly different materials compared to the predicate pump cartridge. However, bench testing showed that the performance specifications (i.e. delivery of the medium) remain unchanged and that the new pump cartridge is as safe and effective as the legally marketed pump cartridge, and does not raise different questions of safety and effectiveness.
#### Non-clinical performance testing
Verification/validation activities from non-clinical testing as described below demonstrate that the differences do not raise any new issues of safety or effectiveness of the subject device compared to the predicate devices.
Electrical safety and electromagnetic compatibility testing were verified by means of IEC 60601-1 and IEC 60601-1-2 in combination with FDA Guidance "Electromagnetic Compatibility (EMC) of Medical Devices", respectively.
Functional testing and design controls to verify adequate performance of the subject device was performed in compliance with 21 CFR 820.30 to ensure that the subject device performs as intended and meets design specifications.
Biocompatibility testing was performed in compliance with ISO 10993-1 and FDA Guidance "Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process" to exclude a negative impact as
{7}------------------------------------------------
a result of the material changes.
Sterilization validation was performed in compliance with ISO 11135 and documentation was provided according FDA Guidance "Submission and Review of Sterility Information in Premarket Notification (510(k)) Submissions for Devices Labeled as Sterile" showing an SAL of 10-6. EO residual testing and limits are in compliance with ISO 10993-7.
Packaging and shelf life validation was performed in compliance with ISO 11607-1 and realtime aged devices. Functional testing was also performed on real-time aged devices.
Software verification and validation was performed in compliance with IEC 62304 and documentation provided according FDA Guidance "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices".
## Conclusion
The subject device has the same intended use, the same fundamental design, the same performance characteristics and energy source as the predicate device. The subject device was tested as described above and the minor differences in technological characteristics were assessed with regards to safety and effectiveness. Taken together, the subject device does not raise new or different questions of safety and effectiveness, and the subject device is substantially equivalent to the predicate device.

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.
