The MyOnyx System is intended for use as a powered muscle stimulation device for relaxation of muscle spasms and muscle re-education, prevention or retardation of disuse atrophy, maintaining or increasing range of motion, increasing local blood circulation, and immediate post-surgical stimulation of calf muscles to prevent venous thrombosis. The MyOnyx System may also be used for transcutaneous electrical nerve stimulation (TENS) and microcurrent electrical stimulation (MET) for the symptomatic relief of acute and chronic intractable pain.

The MyOnyx System is a multi-functional, palm-sized, 4-channel device with embedded firmware and accessories designed for use in physical therapy and rehabilitation under medical supervision. The system that is subject to this 510(k) provides pre-loaded programs and allows users to define programs for electrical muscle stimulation (EMS), transcutaneous electrical nerve stimulation (TENS), and microcurrent stimulation (MET). Biofeedback and incontinence-related indications for use of the device have been cleared under K201014. The device can send a gentle, clinician-adjustable electrical current to underlying nerves and muscles via off-the-shelf surface electrodes cleared by the FDA for this purpose. EMG signals may also be acquired using off-the-shelf, FDA-cleared surface EMG electrodes. The device may be used for muscle and nerve stimulation in one of the following operating modes: - . As a standalone device (autonomous mode); or - . With the MyOnyx Mobile App running on an off-the-shelf tablet (remote control 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 is wireless, via Bluetooth®. Visual, audio and voice feedback and prompts are provided to facilitate device operation. Stimulation data are not recorded. When used in remote control mode, the device can record on the tablet root-mean-square (RMS) EMG signal data at 20 samples/s. 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.

The MyOnyx System is 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.

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). 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.

The MyoTrac Infiniti system is indicated for acute and ongoing treatment of stress, urge or mixed urinary incontinence and where the following results may improve urinary control: Inhibition of the detruser muscle through reflexive mechanisms, strengthening of pelvic floor muscle. It is also indicated during incontinence treatment for assessing EMG activity of the pelvic floor and accessory muscles such as the abdominal or gluteal muscles. The MyoTrac Infiniti system is also indicated for the ongoing treatment of the following conditions: Relaxation of Muscle Spasms, Prevention or retardation of disuse atrophy, increasing local blood circulation, immediate post-surgical stimulation of calf muscles to prevent venous thrombosis, Maintaining or increasing range of motion and Stroke Rehab by Muscle re-education. It is also used for Biofeedback, Relaxation & Muscle Re-Education purposes.

The MyoTrac Infiniti device is a non-implanted electrical stimulator for urinary incontinence, it is intended to re-train the urinary continence mechanisms by way of electrical stimulation applied to the pelvic floor musculature and surrounding structures. The device is indicated for treatment of patients with stress incontinence, urge incontinence or mixed incontinence (a combination of stress and urge incontinence). The indications for this use and labeling will be a subset of the overall indications for use. The MyoTrac Infiniti is an electrical muscle stimulator for contraction of muscles as well. The MyoTrac Infiniti is also an electromyography device. It is intended for medical purposes, such as to monitor and display the bioelectric signals produced by muscles, to stimulate peripheral nerves and to monitor and display the electrical activity produced by nerves. The indications for use are muscle re-education, relaxation and EMG biofeedback.
