Indications for Use
The MyOnyx System subject to this 510(k) is intended for use in the treatment of incontinence.
Device Story
MyOnyx System is a 4-channel, palm-sized device for pelvic floor muscle treatment under medical supervision. Inputs include EMG signals via surface electrodes and pressure data via a pneumatic vaginal probe. Device transforms inputs into biofeedback (visual/audio/haptic) and provides neuromuscular electrical stimulation (NMES) or EMG-triggered stimulation (ETS). Operates in three modes: standalone (autonomous), remote control (via MyOnyx Mobile App on tablet), or computerized (via BioGraph Infiniti software on PC). Clinicians use output to guide patient pelvic floor strengthening or detrusor inhibition. Benefits include improved urinary control for incontinence patients. Device features Bluetooth connectivity, rechargeable Li-ion battery, and capacitive touch interface.
Clinical Evidence
Bench testing only. Verification and validation testing conducted per ISO 14971, including biocompatibility (ISO 10993), electrical safety (IEC 60601-1), EMC (IEC 60601-1-2), and performance testing for nerve/muscle stimulators (IEC 60601-2-10) and electromyographs (IEC 60601-2-40). Usability testing confirmed end-user acceptance. Firmware and software functional verification confirmed performance against design specifications.
Indicated for acute and ongoing treatment of stress, urge, or mixed urinary incontinence, where urinary control may be improved through electrical stimulation that strengthens the pelvic floor muscles or inhibits the detrusor muscle through reflexive mechanisms. The system also uses EMG-based or pressure-based biofeedback to help control and strengthen the pelvic floor muscles in the treatment of urinary incontinence.
Regulatory Classification
Identification
A nonimplanted electrical continence device is a device that consists of a pair of electrodes on a plug or a pessary that are connected by an electrical cable to a battery-powered pulse source. The plug or pessary is inserted into the rectum or into the vagina and used to stimulate the muscles of the pelvic floor to maintain urinary or fecal continence. When necessary, the plug or pessary may be removed by the user. This device excludes an AC-powered nonimplanted electrical continence device and the powered vaginal muscle stimulator for therapeutic use (§ 884.5940).

# Device Description
This 510(k) submission applies to the MyOnyx System, a re-engineered version of the multifunctional predicate MyoTrac™ Infiniti System (K053434), for use in the treatment of incontinence under medical supervision. The system's architecture, design and functionality are based largely on the currently marketed MyoTrac™ Infiniti System with the notable addition of the companion MyOnvx Mobile App for remote access and a pressure biofeedback modality for use in the treatment of incontinence.
The MyOnyx System includes a palm-sized, multi-functional, 4-channel device with embedded firmware and accessories designed for use under medical supervision to provide:
- . electromyographic (EMG) biofeedback;
- pressure biofeedback from pelvic floor muscles; ●
- electrical stimulation (ES); and
- ES with EMG biofeedback (EMG-triggered stimulation or ETS). ●
{4}------------------------------------------------
Up to two stimulation programs may run simultaneously. The device can send a gentle, clinician-adjustable electrical current via surface electrodes on purpose-designed probes. The specified off-the-shelf probes are suitable for EMG biofeedback and electrical stimulation. A small electronic pneumatic pump and pressure sensor device is used with a vaginal provide biofeedback from pelvic floor muscles.
The MyOnyx device may be used in one of the following operating modes:
- as a standalone device for electrical stimulation only (autonomous mode); or ●
- . with the MyOnyx Mobile App running on an off-the-shelf tablet for biofeedback, electrical stimulation and EMG-triggered stimulation (remote control mode); or
- . with the company's BioGraph® Infiniti software running on a personal computer for biofeedback only (computerized mode).
The device is operated via a graphical interface on an LCD screen and a capacitive touch pad with haptic and audio feedback. The connection to a tablet or personal computer is wireless, via Bluetooth". Visual, audio and voice feedback and prompts are provided to facilitate device operation on the standalone device, the MyOnyx Mobile App and the BioGraph® Infiniti software.
When used in remote control mode for biofeedback or EMG-triggered stimulation, the device can record on the tablet root-mean-square (RMS) EMG signal and pressure data at 20 samples/s. Stimulation data are not recorded.
When used in computerized mode, up to 4 devices may be connected to a personal computer for physiological data acquisition and biofeedback. In this mode, the device can record on the PC raw EMG and pressure data at 2048 samples/s. For use in this mode with the BioGraph® Infiniti software the device must be configured through a firmware parameter setting ('extended' configuration).
The device is powered by an internal rechargeable Li-ion polymer battery or via a medical grade power supply / battery charger. The internal battery offers up to 8 hours of autonomous device operation.

# Comparison of Technological Characteristics
The appended table shows a side-by-side comparison of key device characteristics between the subject device and the predicate and reference devices that are used to demonstrate substantial equivalence.
# Substantial Equivalence Conclusion
The assessment of device differences shows that the MyOnyx System does not raise new or different questions of safety and effectiveness as compared to the predicate devices for use in the treatment of incontinence. Furthermore, the results from the verification activities (non-clinical testing) support a finding of substantial equivalence, as they demonstrate that the subject device fulfills its design and risk management requirements, meets equivalent or more recent consensus standards, and it is therefore as safe and as effective for the intended use as the identified predicate devices.

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.
