### 3. Predicate Device
The HS AMICA is substantially equivalent in function and intended use to the following legally marketed device: VivaWave Microwave Ablation System (K053535) and VivaTip Microwave Ablation Probe (K032702). The HS AMICA pump is equivalent to that of Cool-Tip RF Ablation System (K042216).
Though operating at different microwave frequencies (915 MHz for Vivawave and 2450 MHz for HS AMICA, respectively), both system achieve the thermoablation of selected soft tissues located inside the human body through the local delivery of microwave energy.
Both systems are composed by a microwave generator, a single use interstitial probe capable of penetrating into tissues and delivering microwave energy to target tissues through its active distal tip- and by a peristaltic pump for continuous water circulation inside the probe -for applicator cooling-.

The 'H' and 'S' are connected at the bottom, creating a unified design. There is some noise and artifacts around the letters, possibly due to the image's resolution or compression.
Both systems allow the operator to select the microwave output power level and the procedure time, as required by the specific application. In both systems the microwaye power output is started manually by the operator and may either be stopped manually at any time by the operator, or deactivated automatically when the selected procedure time has elapsed. Both systems exhibit software-based electronic control for comfortable operator's setting, handling and monitoring of the ablation procedure. Both systems are endowed with a variety of software and hardware alarms and protections to prevent excessive energy delivery to tissues, overheating of the probe insertion track and other possible criticalities.
The two systems differ in the overall coaqulative performance and in the probe and microwave source design, structure and architecture.
### 4. Device Description
HS AMICA (Apparatus for MICrowave Ablation) is an integrated system for interstitial thermoablation of soft tissues through controlled emission of microwaves.
The system is composed by three interactive devices, namely:
AMICA-GEN: a digitally controlled microwave power source, operating at 2450 MHz and delivering up to 100 W CW (continuous wave); it features a single output channel
AMICA-PROBE: an interstitial single-use coaxial microwave applicator, fed by AMICA--GEN:
AMICA-PUMP: a peristaltic pump for convective applicator cooling through continuous circulation of liguid coolant, fully controlled by AMICA-GEN;
5. Intended Use
HS AMICA is intended for coagulation (thermoablation) of soft tissues; not for use in cardiac procedures.
## 6. Summary of Technological Characteristics
The HS AMICA has the same basic technological characteristics as the predicate device.
HS AMICA achieves soft tissue coagulation by means of a controlled and confined delivery of microwave energy, locally inducing a temperature increase which leads to cellular necrosis.
AMICA-GEN microwave output is a true sinusoidal wave at 2450 MHz, ranging in power from 0 to 100W, suitable for standard thermoablative procedures on almost any type of human tissue. AMICA-GEN has one microwave output channel. AMICA-GEN not only feeds microwave power to AMICA-PROBE -in manual mode, that is delivering an amount of

microwaye power set by the user, or in automatic mode, that is reaching and maintaining a user selected temperature value by self-regulation of the microwave output-, but also serves as user interface for operative parameters setting (ablation time, power to be delivered or target temperature, maximum allowed temperature), continuously performs and displays measurements of the most significant ablation quantities (elapsed ablation time, delivered microwave power, amount of reflected power in % of delivered power, probe temperature), executes safety checks (presence and fine connection of all peripherals, correct functioning of the power supply unit and of the microwave module, monitoring of measured values), treats errors and alert states providing appropriate acoustic and visual feedback to the user, automatically suspends microwave output in case of emergency and, finally, has full control over the peristaltic pump AMICA-PUMP.
AMICA-GEN is a solid state microwave source, capable of generating microwave power through field effect gallium arsenide transistors driven at 12 VDC: no high voltage parts are employed and maximum electrical safety is guaranteed both to patients and operators.
AMICA-GEN has an essential and intuitive user interface simply based on a touchscreen LCD and a rotary knob for selection and confirmation of settings.
AMICA-PROBE is built around a microwave coaxial antenna operated at 2.45GHz (same frequency as commercial microwave ovens), lodged into a stainless steel needle for direct percutaneous insertion: it is thus indicated for interstitial thermoablations. The applicator features:
- 1) a patented miniaturized quarter-wave coaxial choke superimposed to the antenna, which effectively traps reflected microwaves (that is, the portion of delivered power not absorbed by target tissues and propagating backwards along the applicator axis); this mini-choke eliminates uncontrolled back heating effects due to reflections, while keeping the applicator transversal size at a minimum; truly minimal invasiveness and accurate control over the ablated region size and shape are, thus, jointly warranted;
- 2) a sharp stainless steel pyramidal point for straightforward tissue penetration;
- 3) an integrated hydraulic cooling system to remove the heat dissipated due to ohmic losses along the antenna coaxial feeding line: it avoids overheating of the applicator walls and maximizes the microwave power level handled by the applicator for a given antenna size:
- 4) an embedded thermocouple sensor for temperature monitoring inside the applicator:
- 5) an embedded "Write Once Read Many" digital memory chip for software identification of the applicator (factory data ensuring product traceability) and for enhanced safety of use (compatibility checks, protection against improper use or tampering, self-limiting of maximum deliverable power, automatic inhibition of yet used or expired applicators);

Finally, the peristaltic pump AMICA-PUMP is a peripheral device fed and controlled directly by AMICA-GEN, needless of any manual intervention by the user (except for the initial placing of the coolant inlet tubing).
External devices (such as a PC for remote control or data downloading) may be daisy chained to AMICA-PUMP and straightforward communicate with AMICA-GEN.
All materials in contact with patients used in manufacturing AMICA-PROBE are suitable for this purpose and have been used in numerous previously cleared procedures.
Performance testing was executed to ensure that HS AMICA functions as intended and meets design specifications. Sufficient data were obtained to show that the device meets safety and effectiveness criteria and 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.
