Device Story
TomTec-Arena TTA2 is a clinical software package for reviewing, quantifying, and reporting digital medical data. It functions as an add-on to TomTec Image-Arena platforms, TomTec-Arena Server, or third-party platforms. The software processes multimodal and multidimensional medical images to provide clinical measurements, including cardiac catheterization measurements (XA images) and echo exam type measurements. It includes modules for 4D LV/RV function, 4D Cardio-View, 4D MV-Assessment, and 2D cardiac performance analysis. Used in clinical settings, the software assists physicians by providing automated or semi-automated quantification tools to support diagnostic decision-making. The system facilitates workflow through database management, import/export services, and structured reporting/worksheets. It is intended to improve diagnostic accuracy and clinical efficiency by providing standardized measurements of cardiovascular, fetal, and abdominal structures.
Clinical Evidence
No clinical studies were performed. Substantial equivalence is supported by non-clinical bench testing (software verification and validation) and a clinical evaluation based on a literature review. The literature review assessed the benefits and risks associated with the device's intended use, concluding that the benefits outweigh the risks and that the device is safe and effective for its intended purpose.
Technological Characteristics
Software-based platform for multimodal/multidimensional medical data analysis. Features modular architecture (e.g., 4D LV/RV analysis, Echo-Com, Image-Com). Connectivity via integration with TomTec-Arena Server or third-party platforms. Includes XA image calibration and cardiac catheterization measurement tools. Operates as a clinical software package for review and quantification. No specific hardware materials or energy sources; software-only device.
Indications for Use
Indicated for patients with suspected cardiovascular, fetal, or abdominal disease requiring quantification and reporting of structures and function to support physician diagnosis.

There is only a small change for clarification in the notation of the indications for use which do not alter the intended therapeutic / diagnostic effect and do not affect the safety and effectiveness of the device.
#### VI. Comparison of technology characteristics with the predicate device
The Subject Device "TomTec-Arena TTA2" contains modules for analysis of medical studies containing multimodal and multidimensional medical data.
In the actual submission the new modules Reporting and Worksheet are dissolved away from the module Image-Com as independent modules. These functions were also available in the predicate device 1 TomTec-Arena (K132544) imbedded in the module Image-Com. The TomTec-Arena Client functionality has the same technological characteristics as the Image-Arena module of Predicate device 2 (K110667).
For maintenance, all modules of the subject device have been adapted for bug fixing and customer feedback reasons.
Two kinds of changes have been applied to the subject device: Minor changes for operability enhancements or to assure guideline and standard conformance and feature changes of a larger scope. The newly feature changes encompass the Quality Seal (light), cardiac catheterization measurements based on XA images and measurements of the exam type echo. The feature modifications represent a repackaging or new appearance of existing technology to meet the needs of clinical use cases or guideline conformance. Overall, there are no differences in

technological characteristics that raise new or different questions of safety and effectiveness. For detailed information please refer to the attached list of changes.
#### VII. Performance Data
# Discussion according non-clinical performance data testing
Testing was performed according to internal company procedures. Software testing and validation were done at the module and system level according to written test protocols established before testing was conducted.
Testing for the newly added feature changes was performed according to the Test Planning. Test results were reviewed by designated technical professionals before software proceeded to release. All requirements have been verified by tests or other appropriate methods.
The V&V summary (VVS_TomTec-Arena_TTA2_Rev01) lists all test reports in the reference table in chapter 1.1:
The catheterization measurements were tested in dedicated XA test reports [105] (page 3701-3745 serial numbering 510(k)) and [206] (page 4063-4076 serial numbering 510(k)),
the XA calibration in test report [212] (page 4183-4204 serial numbering 510(k)), chapter 4.1.2 (page 4192 serial numbering 510(k)).
The quality seal light was tested in test report [212] (page 4183-4204 serial numbering 510(k)), chapter 4.1.3 (page 4195 serial numbering 510(k)).
The echo exam types were tested in test report [107] (page 3746-3831 serial numbering 510(k)). The 'change tracking' column indicates changed and 'new' measurements to be tested.
Expected results and acceptance (pass/fail) criteria have been defined in all test protocols to ensure that the subject device is safe and effective.
All deviations have been reviewed and classified in chapter 3.7 bugfix verification of the V&V summary. Also, the further handling of the issues is defined.
The incorporated OTS Software is considered validated either by particular tests or implied by the absence of OTS SW related abnormalities during all other Verification & Validation activities.
The summary conclusions state that:
- । all automated tests were reviewed and passed
- feature complete test completed without deviations
- functional tests are completed
- measurement verification is completed without deviations -
- all non-verified bugs have been evaluated and are rated as minor deviations. They are deferred to the next release.

## Discussion according clinical performance data testing
Substantial equivalence determination of this subject device was not based on clinical data or studies.
The overall product concept was clinically accepted and supports the conclusion that the device is as safe as effective, and performs as well as or better than the predicate device.
A clinical evaluation following the literature route based on the assessment of benefits, associated with the use of the device, was performed. The clinical evaluation shows that the published data are relevant and applicable to the relevant characteristics of the device under assessment and the medical procedure for which the device is intended.
Risk analysis aspects (including cyber security) were treated in the risk management report. Based on this document the existing applied methods in the literature and the newly described techniques of the product (which are considered in the risk analysis) were evaluated.
No further risks were identified.
#### VIII. Conclusions
### Conclusion from the analysis of the literature review
- . The Risk-Benefit Assessment concludes that the benefit is superior to the risk, whereas the risk is low. The product TomTec-Arena is therefore harmless for patient and user and the advantages overbalance the probable risks of injury or illness for the patient.
- . The data are sufficient to demonstrate compliance with the essential requirements covering safety and performance of the device in question under normal conditions of use.
- The claims made in the device labelling are substantiated by the clinical data.
### Test Conclusions of non-clinical and clinical performance data
The overall product concept was clinically accepted and test results support the conclusion, that the device is as safe as effective, and performs as well as or better than the predicate device.
No reportable events or problems for the predicate device exist.

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.
