Indications for Use

Unicare is intended to provide electrical stimulation and neuromuscular re-education for the purpose of rehabilitation of weak pelvic floor muscles for the treatment of stress, urge and mixed urinary incontinence in women and to maintain urinary continence in women.

Device Story

Unicare is a battery-powered, single-channel, home-use electrical muscle stimulator. It delivers electrical stimulation to pelvic floor muscles via a reusable vaginal probe or optional self-adhesive skin electrodes. The device operates by generating symmetrical bi-phasic rectangular waveforms at specific frequencies and pulse widths to facilitate neuromuscular re-education. Users control stimulation intensity via manual push-buttons on the unit. The device is intended for OTC use by women to treat urinary incontinence. By strengthening pelvic floor muscles, the device aims to improve continence and reduce incontinence symptoms. It is a non-implanted device designed for personal use in a home environment.

Clinical Evidence

No clinical data provided. Substantial equivalence is supported by bench testing, including biocompatibility (ISO 10993-1), electrical safety (IEC 60601-1), electromagnetic compatibility (IEC 60601-1-2), and nerve/muscle stimulator performance standards (IEC 60601-2-10), alongside software verification and validation.

Technological Characteristics

Battery-powered (3.7V 80 mAh Li-ion) single-channel stimulator. Delivers symmetrical bi-phasic rectangular pulses. Max output 99.0 mA (+/- 10%) at 500Ω. Includes reusable vaginal probe and self-adhesive electrodes. Standards: ISO 10993-1 (biocompatibility), IEC 60601-1 (safety), IEC 60601-1-2 (EMC), IEC 60601-2-10 (nerve/muscle stimulators).

Indications for Use

Indicated for women with stress, urge, or mixed urinary incontinence requiring pelvic floor muscle rehabilitation and maintenance of urinary continence.

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).

Dear Saskia Eldridge-Hinmers:

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.

#### Device Description 4.

Unicare is battery powered, single-channel, home-use electrical pelvic floor muscle stimulator. The device is supplied with a non-sterile, reusable (single-patient use) vaginal probe and self-adhesive electrodes which connect to the control unit by cable and plugs. The vaginal probe is inserted into the vagina. The optional self-adhesive electrodes is placed on patients' intact skin and is used for the treatment of only urge urinary incontinence in women. Electrical stimulation is delivered via the vaginal probe or the self-adhesive electrodes to the pelvic floor muscles. This electrical muscle stimulation works as a rehabilitation and training for pelvic floor muscles for the treatment of stress, urge and mixed urinary incontinence in women. The level of electrical stimulation of the Unicare can be controlled by the end user using manual push-button controls. This device is intended for over the counter (OTC) use.

#### 5. Indications For Use
