Indications for Use
The GMP/Wireless Medicine LifeSync™ System is intended for use as a radiofrequency signal transmitter and receiver of diagnostic electrocardiographic physiological signals which are displayed on the ECG monitors of various manufacturers' systems that have been validated for compatibility. ECG systems that are not currently wireless in operation will now be able to be used in a wireless fashion by virtue of being connected to the GMP system. The LifeSync™ System will also transmit the patient respiration waveform for those ECG systems that include a respiration function. The GMPIWireless Medicine LifeSync™ System will eliminate the wires between the ECG patient and the ECG monitor and will replace the traditional ECG cable with a radio link. The GMP|Wireless Medicine LifeSync™ System will support the standard 5-lead ECG hook-up (via the Continuous Leadwear™) for monitoring and has the capability to add the remaining V1-V6 precordial leads (via the Discrete Leadwear™) for 12-lead discrete ECG recording.

#### E. SUBSTANTIAL EQUIVALENCE SUMMARY
The GMP!Wireless Medicine LifeSync™ System is a medical device and has a similar indications for use statement as the predicate device. The differences do no alter the intended diagnostic effect--both devices have essentially the same intended use. The device also has the same technological characteristics as the predicate device. Since a comparison of the descriptive characteristics of the proposed and predicate devices may not be sufficiently precise to assure equivalence, performance data are provided. The results of the performance testing demonstrates substantial equivalence.
As recommended in the 11-5-98 FDA Guidance Documents for Industry --Diagnostic ECG Guidance, and Cardiac Monitor Guidance, substantial equivalence which is the primary basis for 510(k) concurrence, has been assessed and is demonstrated in this 510(k) submission by evaluating the LifeSync™ System for conformity to ANSI/AAMI EC11-1991 "Diagnostic Electrocardiographic Devices", ANSI/AAMI EC13-2002 Cardiac Monitors, Heart Rate Meters, and Alarms, and to ANSI/AAMI EC38-1998, "Ambulatory Electrocardiographs." The LifeSync™ System's patient Continuous and Discrete

Leadwear™ have also been assessed for conformity to ANSI/AAMI EC53-1995, "ECG Cables and Leadwires".
#### F. TECHNOLOGICAL CHARACTERISTICS
Both devices use electronic components to process and transmit ECG signals via a radiofrequency link. While the details of the transmission process are different. the basic technology is the same.
#### G. TESTING
In-vitro performance testing was conducted in accordance with the standards. ANSI/AAMI EC11 - 1991, "Diagnostic Electrocardiographic Devices" and ANSI/AAMI EC38-1998, "Ambulatory Electrocardiographs", ANSI/AAMI EC13 - 2002 "Cardiac Monitors, Heart Rate Meters, and Alarms", and AAMI/ANSI EC53 - 1995 "ECG Cables and Leadwires." That is, since the GMP device is intended and is labeled to be compatible with a number of manufacturers' diagnostic/discrete ECG and continuous cardiac monitoring systems, testing in accordance with the EC11, EC13, and EC38 standards was performed in order to assure compatibility between the LifeSync™ System and the ECG Systems that are covered by the standards.
The LifeSync™ system was tested to the requirements of EN 60601-11:1990 "Medical electrical equipment Part 1. General requirements for safety". IEC 60601-1-2:2001 "Medical electrical equipment Part 2. Collateral Standard: Electromagnetic compatibility", and IEC 60601-2-27:1994 "Medical electrical equipment Part 2. Particular requirements for the safety of electrocardiographic monitoring equipment", and it met all of the applicable requirements.
#### H. CONCLUSIONS

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.
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.
