## 5.9 Device Description
BT3/6. BT12 is a compact ECG device which is worn on the body and is capable of wireless data transmission. With the BT3/6 type, 2 ECG leads (II - III according to Einthoven) can be measured via a 4-pin cable. The receiving unit can calculate four additional leads (lead I according to Einthoven, aVL, aVR, aVF according to Goldberger).Type BT12 has a 10-pin cable, which, in addition to the leads of the BT3/6 variant, can also measure the 6 leads according to Wilson. With this cable, one can select among 3-, 6- or 12-channel ECG measurements. The cables of the BT are pluggable and therefore can be easily changed.
The electrode clips on the patient cables are suitable for connection to button and tab electrodes. It has an integrated electrode contact detector and a heart rate meter, the results of which are displayed on an integrated LCD display. Thanks to the integrated radio data transmission technology, BT3/6, BT12 is able to transmit ECG data online over a range of up to 10 m to a monitor or recording unit for further evaluation.
BT3/6, BT12 can be used in all medical applications where the long, stiff trunk cables are a problem due to their weight, their motion artifacts or their electromagnetic susceptibility or because they limit the patient in his freedom of motion. Especially significant are the applications in which it is necessary for the patient to move around freely, for example when the patient is undergoing a stress electrocardiogram.
BT3/6, BT12 is compact and simple to operate. A clip allows the device to the patient's clothing. BT3/6, BT12 is powered by two standard AA cells.
Patient contacting components are the electrodes. BT3/6, BT12 is intended for use with approved. biocompatible electrodes only.
A user manual with detailed description of the device is submitted in section 13 "Proposed Labeling".

Both devices are intended for continuous wireless transmission of ECG signals and both are portable due to battery-supply and light weight. Both devices are capable of acquiring the ECGs at remote sites and transmitting them via radio transmission to an appropriate receiving station. Therefore, the device under consideration and the predicate device are very similar in their basic functions. The predicate device claims conformance with the ECG standards ANSI/AAMI EC11:1991, and ANSI/AAMI EC38:1998. BT3/6, BT12 is conform with hardware requirements of EC11 and EC38. Exception is the offset-voltage requirement of ±300mV. With BT3/6, BT12 an offset of up to ±190mV does not influence the baseline of the ECG signal. But performance is better than that of the predicate device which states DC offset of only ±75 mV.
The differences in technological characteristics between BT3/6, BT12 and the predicate device can be summarized as follows:
{5}------------------------------------------------
The resolution of the BT devices is higher than that of the predicate (15 bit compared to 10 bit) which results in a better ECG signal quality.
The predicate device is available only for the acquisition of 12-lead ECGs, whereas the device under consideration is available for measuring either a 12- or a 3/6-lead ECG (BT12 and BT3/6).
CMRR of the BT devices is higher than with the predicate (>94 db compared to 60 db). This results in a better ECG signal quality in the presence of interference signals.
Input impedance is specified higher with the BT devices (20 MΩ compared to >10 MΩ). Therefore, ECG signal quality is less dependent on electrode contact quality with the BT as with the predicate.
The two devices differ in their data storage functionality. The BT stores data only when the wireless radio connection is interrupted, e.g. when the patient leaves the transmission range. After the connection is re-established the stored data is transmitted to the receiving unit. Interruption of the transmission is indicated on the device. The BT devices are not intended for use as Holter monitors. The CG-7000X-BT has a limited event storage capability of up to 40 ECG recordings.
The BT devices and the predicate are capable of continuously transmitting ECG data.
The graphic display of the CG-7000DX-BT is able to display the measured ECG, while the BT devices can display the ECG on the receiving unit only. But, the predicate is of low resolution and should not be used to make a diagnosis.
The BT devices have a higher degree of protection against penetration of water (IPX3).
## 5.13 Summary of Device Testing
The BT3/6, BT12 has been tested according to IEC 60601-1 and IEC 60601-1-2 by accredited laboratories and has shown full compliance to these standards and the standards listed in chapter 9 of this 510(k).
BT3/6, BT12 fulfils only those parts of the standards ANSI/AAMI EC11:1991, and ANSI/AAMI EC38:1998 that relate to hardware requirements. In case the device is used in combination with appropriate software and the user manual is adapted to the standards, it is possible to completely comply with these standards. Since the BT3/6, BT12 is supplied without diagnostic/interpreting software, the manufacturer cannot claim full compliance to ANSI/AAMI EC11:1991, and EC38:1998.
The software was tested as described in section 16 "Software". The corresponding FDA software quidelines were followed.
### 5.14 Conclusions
Based on the above, Corscience GmbH & Co. KG concludes, that BT3/6, BT12 is substantially equivalent to a legally marketed predicate device and iffective for its intended use, and performs as well as or better than 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.

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.
