### 6.12 Device Description
The PhysioGlove ET system is a 12-lead electrocardiograph capable of recording and transmitting standard ECGs for the purpose of cardiac monitoring and diagnosis in a remote location. The PhysioGlove ET system consists of the following 3 primary components:
The PhysioGlove - a glove that incorporates a system of Ag/AgCl electrodes for use in recording 12-lead ECGs. The PhysioGlove of the ET system is a modification of the cleared PhysioGlove ES-1 system (originally cleared under K083677 and later incorporated under K103791). In the ET system, however, the PhysioGlove encompasses also electronic elements (mainly a data acquisition circuitry and software packed into the glove, based on the cleared PhysioGlove ES-1) and a recording and transmitting circuitry to permit the transfer of the ECG data to a mobile platform.
The Mobile Platform Software - designed to be downloaded to a compatible mobile platform such as a smart cell-phone, a tablet computer, or another communication device. The proprietary Mobile Platform Software is responsible to provide the user with the PhysioGlove ET system operational instructions, as well as to receive the ECG data from the PhysioGlove and to transfer them to the receiving center. No graphical presentation of the acquired ECG is enabled on the mobile platform.
The Mercury Telemedicine System (MTS) - proprietary software designed to be installed on a computer in the PhysioGlove ET receiving center (e.g., Nurse Station). The MTS is responsible to receive the recorded ECG data, save it in a database and present it to a
{6}------------------------------------------------
medical professional who is capable of interpreting the results. The MTS is based on the PhysioGlove ES-1 software (originally cleared under K050674 and later incorporated under K103791).
The PhysioGlove ET system operates as follows:
The PhysioGlove records the patient's ECG and sends the data via Bluetooth to a mobile platform. Then, the recorded data is automatically transferred via the Internet using Wi-Fi to connect to a modem or via GPRS cellular communication. The data is sent to a receiving center (e.g., Nurse Station) to be reviewed by a medical professional who is capable of interpreting the ECG data.
### 6.13 Substantial Equivalence
The PhysioGlove ET System is substantially equivalent to the SelfCheck and PhysioGlove ES-1 with regard to intended use and indications for use. All three devices are reusable 12-Lead ECG examination systems, intended for recording of ECG. Both the PhysioGlove ET and the SelfCheck device are designed to be used by a patient or a health care professional who are concerned about their heart health and have problems that are suggestive of abnormal heart function.
Also, all three devices, the PhysioGlove ET, the SelfCheck Device, and the PhysioGlove ES-1 System, include hardware (HW) and software (SW) elements responsible for the collection and conditioning of the ECG signal so that it can be transmitted to another location for display. In the PhysioGlove ET, and similarly in the SelfCheck Device, the ECG recording may be conducted at home while the data display is performed at a remote location such as hospital, physician's office or a monitoring center.
The PhysioGlove ET System and the SelfCheck Device both use a Mobile Platform (e.g., a smart cell-phone, a compatible generic PDA or another communication device). The platform receives the ECG signal from the ECG acquisition element (the PhysioGlove or the PMP4 SelfCheck ECG) via Bluetooth and transmits it to the receiving center via cellular communication. Both devices contain methods for error testing and retransmission of the data.
The essential functionality of the SW elements included in the PhysioGlove ET system and its two predicates is substantially similar, i.e., receive the ECG data generated from the electrodes and transfer the digitized ECG data to the receiving center. Specifically, the PhysioGlove ET SW is a modification of the cleared PhysioGlove ES-1 SW (K103791) and thus, substantially equivalent the company's cleared device.
{7}------------------------------------------------
### 6.14 Performance Testing
Performance testing was conducted in order to demonstrate the performance, safety and usability of the PhysioGlove ET system. The testing plan included electrical safety and electromagnetic compatibility testing (according to IEC 60601-1, Medical Electrical Equipment - Part 1: General Requirements for Safety, and IEC 60601-1-2, Medical Electrical Equipment - Part 1-2: General Requirements for Safety - Collateral standard: Electromagnetic Compatibility - Requirements and Tests ), compliance with performance standards (IEC 60601-1-11, General requirements for basic safety and essential performance - Collateral Standard: Requirements for medical electrical equipment and medical electrical systems used in the home healthcare environment, and IEC 60601-2-25,
Particular requirements for the basic safety and essential performance of electrocardiographs). SW validation testing and a usability study.
Test results indicated that the PhysioGlove ET functions as expected and is substantially equivalent to the predicate devices for its intended use. Therefore, it is concluded that the PhysioGlove ET system is substantially equivalent to its predicate devices without raising any new questions of safety and/or effectiveness.

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.
