#### Device Description
The Emprint™ SX Ablation Platform with Thermosphere™ Technology is microwave-based system intended to deliver energy through an antenna inserted into soft tissue for the purpose of coagulating (ablating) a defined tissue volume. The Emprint™ SX Ablation Platform utilizes a 2450 MHz 100W generator to deliver power to a single microwave ablation antenna. The platform is software-controlled and a touchscreen Graphical User Interface is used to select the desired ablation time (up to 10 minutes) and power (5 to 100W) settings. Using an optional temperature probe, the ablation platform can be set to monitor the temperature of a desired target and to automatically turn the generator off, when the target reaches a pre-set temperature. The ablation platform uses circulating, room-temperature, normal saline to cool the non-radiating portion of the antenna shaft and to provide a consistent ablation zone. The normal
{4}------------------------------------------------
saline is pumped from an IV bag through the antenna shaft and back to the IV bag in a closed system.
Using an optional/selectable navigation feature, the Emprint™ SX Ablation Platform assists physicians in the accurate placement of the trackable Emprint™ SX Navigation Antenna into a target anatomical structure by overlaying the image of the antenna and its trajectory onto an ultrasound image in real time.
Sensors are attached to platform-compatible, open and laparoscopic ultrasound probes and to the platform's trackable antenna. These sensors detect fluctuations in an electromagnetic field emitted from the system's Table Top Field Generator (TTFG). The TTFG is placed underneath the patient and transmits positional information that is processed by the system's navigation hardware and interpreted by its software. The platform's software allows the surgeon to see a representation of the ablation zone on an auxiliary display and the system's operator to control the ablation system via the touchscreen interface.

## Technological Characteristics
The Emprint SX™ Ablation Platform with Thermosphere Technology is a microwave ablation system. As shown in the following Comparison Table, it relies on the same principles of operation and fundamental technology, and has the same performance characteristics as the predicate device – with respect to its intended use of soft tissue ablation in open, laparoscopic and percutaneous procedures. The platform's optional navigation feature does not raise new questions of safety or effectiveness and performance testing was conducted to evaluate the added functionality/technological differences.
#### Performance Testing
The performance of the ablation platform was verified through subsystem and system-level testing. For the platform's sterile disposables, verification testing included evaluations of the products' sterility (10° SAL), residual EO/ECH levels, biocompatibility, shelf life (2 years) and packaging. Additionally, the disposable devices underwent functional testing, following exposure to mechanical and electrical stressors.
At the system level, electrical safety and electromagnetic compatibility were evaluated to establish conformity to applicable IEC 60601 safety standards. Ex vivo tissue testing was conducted to further characterize the platform's performance. Ablation zone size and shape were measured at selected generator time and power settings and were equivalent to the predicate system. The accuracy of the platform's navigation feature was evaluated and is specified in the product's labeling. Packaging for the platform's cart and navigation equipment also was validated. The system's ability to function as designed across a wide range of operating conditions (altitude, temperature and humidity) was verified in an environmentally controlled chamber. Human factors evaluations and a design validation demonstrated that the ablation platform's navigation feature met user needs and expectations.

Performance testing demonstrated the Emprint™ SX Ablation Platform's compliance with the following international, safety standards.

## Animal Testing
Two animal studies were conducted to further evaluate the safety and performance of the Emprint™ SX Ablation Platform.
The objective of the first study was to evaluate the performance of the platform's disposable accessories (navigation antenna, open ultrasound tracking sensor and laparoscopic ultrasound tracking sensor). The performance evaluation was conducted in a porcine model and included the measurement of maximum insertion and extraction forces for the Emprint™ SX Navigation Antenna and confirmation of the ultrasound tracking sensors' soft tissue compatibility. The average maximum forces required to insert the navigation antenna through the body wall and into a soft tissue target and to extract the navigation antenna from an ablated soft tissue target were equivalent to previously reported measurements for the predicate device. Tissue compatibility testing conducted with each of the different ultrasound tracking sensors resulted in no visible tissue trauma or damage and confirmed their suitability and safety for clinical use.
A second in vivo study was conducted to demonstrate that the platform performed as expected when used, first, to navigate to previously placed fiducial targets in a porcine model and, secondly, to ablate the targeted soft tissue. The comparative study was designed to demonstrate the equivalence of the Emprint™ SX Ablation Platform and predicate Emprint™ Ablation System, with respect to safety and performance, when used in an animal model and surgical environment that closely simulated human clinical use. In vivo testing of the Emprint™ SX and predicate systems demonstrated that the performance and procedural safety of the new device was equivalent to or better than its predicate. The incidence/severity of intra-operative bleeding after antenna placement was similar with both systems and there were no macroscopic differences between ablation zones created with the two systems. Finally, the number of attempts needed by participating physicians to place the antenna was fewer when using the navigation-quided ablation platform compared to the previous-generator Emprint™ Ablation System, suggesting that the navigation feature enhances the platform's overall usability.
#### Clinical Testing
Clinical studies were not required to demonstrate the substantial equivalence of the new ablation platform and its predicate.

# Comparison to Predicate Device - Key Differences and Similarities
Essential differences between the Emprint™ SX Ablation Platform and the predicate device include (1) software (vs. manual) control of the microwave generator and pump and, (2) the addition of the optional navigation feature (comprised of hardware and software components). Both systems incorporate a 2.45 GHz microwave generator, a cooling pump, and are compatible with the same accessories.
The Emprint™ SX Ablation Platform's electromagnetic navigation feature uses the previously cleared Emprint Percutaneous Antenna – modified to include an embedded, navigation sensor. For procedures where the navigation feature is not used, the unmodified Emprint Percutaneous Antenna (K163105) can be used with the software-controlled ablation platform in percutaneous, laparoscopic, and intraoperative procedures.
A detailed comparison of the subject and predicate devices is provided in the following table.

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).

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.
