- Operator controls are limited to on/off and activation o
- The circuitry is completely dead except for on/off and battery status o indicator lights when the unit it not activated for patient application
- Output power is limited to under 50 watts, obviating the requirement o for neutral electrode cable fault or pad adhesion alarms
The Liger Medical ESU-110 is powered by an internal lithium-ion battery to allow safe usage at locations where A/C line current is unavailable or unreliable. Battery operation also results in ready portability and more complete isolation than is achievable by a system powered by A/C line current.
The Liger Medical ESU-110 has an integrated smoke evacuation fan designed to remove smoke and noxious odors produced by surgical smoke during laser and electrosurgical procedures. This component of the system has been designed with a motor to draw the surgical smoke from the surgical site through vacuum tubing and into a microbial and charcoal filter where the surgical smoke is processed to remove odors. The smoke evacuation is completely automated with the activation being integrated into the activation circuit of the clectrosurgical gencrator. When the Liger Medical ESU-110 is activated, the smoke evacuation fan automatically activates as well. This component of the Liger Medical ESU-110 is fouind to be substantially equivalent to the Utah Medical Products Finesse 3rd Generation. The smoke evacuation component of the Liger Medical ESU-110 presents virtually no potential for risk as there is only a single moving part which is fully encased and not accessible by the user. Further, the smoke evacuation component is never intended nor designed to come into contact with the patient and has no potential for electrical ground or shock.
The Liger Medical ESU-110 is substantially equivalent to the predicate devices Finesse 3rd Generation and Aaron 950 when taking into account that the ESU-110 is designed ot be a single-purpose, portable unit while the Finesse 3rd Generation and Aaron 950 are multi-purpose units. In terms of output type, number of connections, types of connections, activation method, indicators, safety class, patient circuit, output impedance, applied part classification, neutral electrode isolation, activation tone, leakage current, output mode, frequency, crest factor, activation cycle, ooutput controls, compatible accessories, compatible neutral electrodes, and audio frequency all three units are equivalent. The Liger Medical ESU-110 is equivalent to the predicate devices in terms of peak-to-peak voltage when the predicate devices are set to the fixed value of 49W which the Liger ESU-110 is designed to output. For each other parameter, the Liger ESU-110 is cither exempt from regulation due to being limited to under 50W of output or is reflecting the properties of battery-operation vs. main line operation. Substantively, the Liger Medical ESU-110 is equivalent to the predicate devices.
The Liger Medical ESU-110 conforms to IEC 60601-1-2:2007 and IEC 60601-2-2:2009 Safety and Performance: requirements for electrical and electromagnetic safety passing the standard's requirements for patient protection, protection against neuromuscular stimulation, excessive temperatures, spillage, output indication, and protection against short circuits. Each of these safety concerns were tested in-house by Liger Medical and found to meet

or exceed all applicable requirements of the IEC 60601-1-2:2007 and IEC 60601-2-2:2009. The outside intereference was negligible. Further, the ESU-110 generates no significant EMDs when idle, when activated, or when activated with a load. Compliance for both IEC 60601-1-1:2009 and IEC 60601-2-2:2009 are claimed in section 9.0. Specific testing protocols, testing procedures, tests conducted, and resulting data which support this summary are located in section 17.0.
In conclusion, the in-house test data collected for the Liger Medical ESU-110 strongly suggests that the ESU-110 unit is substantially equivalent to both the Bovie Aaron 950 and the Utah Medical Finesse 3rd Generation in both safety and performance.

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.
