Device Story

NeuroTrac® MyoPlus Pro is a single-channel pelvic floor muscle stimulator; assists patients with urinary incontinence to increase muscle control; overcomes pelvic muscle dysfunction. Inputs: EMG signals from pelvic floor via vaginal probe. Operation: device functions as electromyograph (EMG) and electrical stimulator (STIM); features EMG-triggered stimulation (ETS) mode. Output: symmetrical, rectangular, biphasic electrical stimulation pulses delivered via vaginal probe. Used in clinic or home; operated by physician or patient. Output allows healthcare providers to monitor muscle activity and provide targeted rehabilitation; benefits patient by strengthening pelvic floor muscles and improving urinary control.

Clinical Evidence

Bench testing only. Testing included electrical safety (IEC 60601-1:2020), electromagnetic compatibility (IEC 60601-1-2:2020), software verification/validation, and cybersecurity risk management. Performance metrics (net charge, phase charge, power density) were calculated and met all pre-determined acceptance criteria.

Technological Characteristics

Single-channel pelvic floor stimulator; constant current; biphasic, symmetrical, rectangular waveform. Frequency 2-100 Hz. Power: 4xAAA alkaline batteries (6V). Applied parts: vaginal probe (cleared under K122194) and skin electrodes. Standards: IEC 60601-1:2020, IEC 60601-1-2:2020.

Indications for Use

Indicated for adult women (aged >22) with stress, urge, or mixed urinary incontinence for pelvic floor muscle rehabilitation, relaxation training, and muscle re-education.

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).

Predicate Devices

Dear Nigel Verity:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

The sponsor used the primary predicate to support the STIM mode of the subject device and used the secondary predicate to support the EMG and ETS modes of operation of the subject. As evidenced by the above table, the subject and the predicate devices have the same intended use but differ in technological characteristics. Performance testing was conducted on the subject device, and it was established that the differences in technological characteristics do not raise different questions of safety or effectiveness.

# 7. SUMMARY OF NONCLINICAL TESTING:

Below is a list of the tests that were performed and successfully completed for the subject device per the specified guidance and standards:

- Electrical Safety testing according to IEC 60601-1: 2020 - Medical electrical equipment -
