Indications for Use
The M5 Recorder is a small digital ambulatory ECG recorder intended for use by professionals to acquire ECG data from a patient in a clinical, point of care or at a patient setting. The M5 Recorder uses a rechargeable lithium polymer battery and can record ECG up to 21 days (3 channels) on the torso of a patient through a M5 Patch ECG electrode or M5 lead set and standard electrodes (length or recording time is based on the sample rate and channel selection). The patient's ECG is recorded to the M5 Recorder and then transferred via the M5 USB cable to a PC-based ambulatory ECG analysis system (such as the Global Instrumentation M12A application) for review by physicians or other qualified personnel. Due to the continual wearing of an ambulatory ECG monitor, this is a medical device that is used both in professional healthcare facilities and outside those facilities. This description meets the definition of a home use device. The M5 Recorder is intended for use by adults and pediatric sub-groups (weighing more than 10 Kg). The intended use, expected service life and conditions for transport and storage were taken into consideration for selection and treatment of materials used in the construction of the M5 Recorder.

## V. Description of the Device
The M5 Recorder is a small, lightweight ambulatory electrocardiograph (ECG) recorder that records ECG continuously. The M5 records 1 or 3 channels of ECG up to 21 days. The battery duration of the M5 is dependent on the configured settings of sample rate and channel selection. The device is composed of the ECG recorder that can be utilized with a patch electrode or with a patient cable lead set using off the shelf electrodes intended for long-term monitoring. The device snaps onto the patch electrode or patient cable lead set and automatically begins recording. The recording will continue until either the M5 completes the programmed monitoring session, is removed from the Patch Electrode or patient cable, or the battery is depleted.
At the end of the recording, the device can be plugged into a PC via the M5 USB cable. The ECG recording can be transferred to a PC where processing software can transfer the data to a format that can be processed through recording processing software provided by recording processing software manufacturers and analyzed by qualified healthcare providers. The M5 recorder acquires ECG data and does not perform any data processing or arrhythmia analysis of the ECG data. Only the M5 Recorder is part of this 510K application.
During the recording period the patient wears the M5 Recorder with the patch electrode on the upper chest near the sternum. If using the M5 Recorder with the patient cable, the patient will wear off the shelf electrodes (2 - 5) positioned on the torso. The M5 Recorder can be worn continuously up to 14 days with the same patch electrode and up to 4 days with the patient cable and same set of off the shelf electrodes.
The M5 Recorder consists of a microprocessor, measuring circuit, memory, data storage, light emitting diode (LED), and contacts to the electrode. In addition to that, the M5 Recorder contains firmware to control the collection of the ECG data and allows transfer to the processing software. The M5 Recorder has an internal Bluetooth radio that may be utilized with a host ambulatory ECG analysis system (such as the Global Instrumentation M12A application) to allow the qualified health care provider a view of the patient's ECG immediately following hook-up. The LED on the M5 Recorder will flash. This provides visual confirmation to the professional that the recorder is actively collecting data.
The M5 recorder also has a button on the recorder. The primary function of the button is to
{5}------------------------------------------------
provide an event feature where the patient presses the button on the recorder when they feel a symptom. The LED will flash to provide feedback to the patient that the event marking has occurred. The button also allows for a battery status check.
The associated spare parts that are part of the M5 Recorder system are the M5 Patch Electrode, M5 Patient Cable, M5 USB Cable, and GI Wall Charger.
## Components, Spare parts and Collateral Devices - Overview
## M5 Recorder
The M5 Recorder has interfaces to a compatible M5 Patch Electrode, M5 Patient Cable, and M5 USB Cable. The Recorder is reusable and rechargeable. The battery is a rechargeable lithium polymer battery with built-in protection circuit. Charging the M5 Recorder battery is done by use of the M5 USB cable with a proprietary connector which can only be connected to the M5 Recorder when it is not connected to the M5 Patch Electrode or M5 Patient Cable. The Recorder contains internal non-volatile storage that stores ECG data until uploaded to host system. The M5 Recorder also contains firmware for recording ECG, storing ECG, and user interface. When the recorder is connected to the host system through the M5 USB Cable, the recorded ECG files are accessible via a proprietary communication protocol. All M5 Recorder data files are in a proprietary file format. All communication to the M5 Recorder requires proprietary encrypted authentication.
The recorder has a serial number and product number in a GS-128 bar code format to secure the traceability of the equipment and the data during and after recordings.
The case of the M5 Recorder is a Valox 357U polycarbonate (PBT) for medical device applications and has ISO 10993 certification.
## M5 Patch Electrode
The electrode is non-sterile and disposed of after a single use. The patch electrode (spare part to M5 Recorder) is a passive part. The electrode consists of one layer of one-sided adhesive tape that runs the full length of the electrode. This adhesive tape allows the electrode to be placed on the upper sternum. The electrode gel is located on the underneath side of the adhesive tape. Through this electrode gel the ECG of the patient is recorded. The M5 Patch Electrode provides a single channel ECG recording. The top side of the electrode has a plastic cradle that holds the M5 Recorder in place and provides an electrical connection to the patch electrode conductor path. The conductor paths are flex strips that run between the cradle and the electrode gel. A release liner is placed on the underside of the electrode. The release liner covers the adhesive tape and the electrode gel. This liner is peeled off when placing the M5 Patch Electrode on the upper sternum. The electrode must be connected to the M5 Recorder to have any practical use.
Per the U.S. FDA Class II Special Controls Guidance Document: Electrocardiograph Electrodes, issued on July 21, 2011 "the FDA has determined that a 510(k) is not necessary to provide reasonable assurance of the safety and effectiveness of this generic type of device if the manufacturer follows the recommendations in this special controls guidance to address the issues identified in this guidance." The scope of the guidance includes "bare ECG electrodes or ECG electrodes that incorporate as part of their design, a conductive gel, an adhesive system or a lead wire". Per this guidance, we have the device specifications, composition, formulation, component specifications, engineering drawings with dimensions & composition, written description, description of how the M5 Patch Electrode connects to the M5 Recorder and a list of features and specifications in tabular format.
### M5 Patient Cable (lead set)
The M5 Patient Cable (spare part to M5 Recorder) is a reusable lead set option for collecting ECG recordings in single or three channel modes. The patient cable is available in 2 lead, 3 lead, 4 lead and 5 lead options and uses off the shelf electrodes suited for ambulatory ECG
{6}------------------------------------------------
monitoring. The patient cable features a custom connector that attaches to the M5 Recorder. The placement of the electrodes are left arm (LA), right arm (RA), left leg (LL), right leg (RL), and V. The V lead electrode may be positioned in any of the precordial (V1 - V6) placements based on physician preference.
The M5 Patient Cable is used with standard electrodes intended for longer duration ambulatory ECG recording. The off the shelf electrodes feature a snap which provides connection to the leads of the M5 Patient Cable.
## M5 USB Cable
The M5 USB Cable (spare part to M5 Recorder) is used to recharge the M5 Recorder and to upload the stored ECG data from the recorder to a host system. The M5 USB Cable features a proprietary connector design to match to the M5 Recorder. The opposite end of the cable uses a standard USB Type A male connector.
## GI Wall Charger
GI Wall Charger is a 60601-1 compliant medical grade power supply with integral USB jack used with the M5 USB Cable for charging the M5 Recorder.

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.
