Device Description

The device consists of a hand held electrostimulation unit and an injection molded thermoplastic applicator that supports two stainless steel electrode rings that apply electrical stimulation to a patient in order to help train neuromuscular tissue in the pelvic floor for improvement or restoration of urinary continence for women. The applicator includes a pressure transducer that provides biofeedback relations of the pelvic floor muscles. The electrical stimulation energy and the power for the transducer are conducted to the electrodes via a six conductor cable and connector that plugs into the PFS-300. The transducer output signal is conducted back to an LCD graphical display by the same cable.

The PFS-300 is indicated for use to help train the pelvic floor muscles using electrical stimulation and biofeedback. The PFS-044 is a vaginal applicator that is used with the PFS-300. The PFS-300 is a battery powered electrostimulation device that applies electrical stimulation through electrodes on the PFS-044 applicator.

AI/ML Overview

The provided text is a 510(k) summary for the Liberty Plus System (PFS-300), a non-implanted electrical continence device. The document primarily focuses on establishing substantial equivalence to previously cleared predicate devices and does not describe acceptance criteria, a specific study proving device performance against those criteria, or the detailed aspects of a clinical trial.

Therefore, I cannot extract the requested information based on the provided text. The document states that "Laboratory tests of the PFS-300 and the PFS-200 have demonstrated that they provide equivalent electrical stimulation of the pelvic floor muscles" and that "The PFS-300 and the Cardio Design Pty Ltd. PFX both display readings of the pressures generated by contractions of the pelvic floor muscles." However, it does not provide details about these laboratory tests, including acceptance criteria, sample sizes, ground truth establishment, or expert involvement.

510(k) Summary

January 3, 1997

Trade Name: Liberty Plus System, PFS-300 Electrical Pelvic Floor Stimulation System With Biofeedback Common Name: Nonimplanted Electrical Continence Device. 21 CFR §876.5320 Classifications: and Perineometer, 21 CFR §884.1425

The Utah Medical Products, Inc. (UMP) Liberty Plus System (PFS-300) is substantially equivalent to a combination of the UMP Liberty PFS System (PFS-200), cleared for marketing under K960496, with the Cardio Design Pty Ltd PFX Pelvic Floor Exerciser, cleared for marketing under K945611.

The technological characteristics of the UMP PFS-300 are substantially equivalent to the UMP PFS-200 since the stimulation output is identical. The PFS-300 has an LCD displays the oscillographic output from the pressure transducer in the PFS-044 applicator. The PFS-044 probe is substantially equivalent to the PFS-042 probe used with the PFS-200. They are the same size and shape and are manufactured from the same materials. The only difference is the pressure transducer that is enclosed in the PFS-044 that provides biofeedback to the user. The new device and the predicate device are both manufactured using biocompatible materials.

Laboratory tests of the PFS-300 and the PFS-200 have demonstrated that they provide equivalent electrical stimulation of the pelvic floor muscles. The PFS-300 and the Cardio Design Pty Ltd. PFX both display readings of the pressures generated by contractions of the pelvic floor muscles.

Dear Mr. Cornwell:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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 (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. 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.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Good Manufacturing Practice for Medical Devices: General (GMP) regulation (21 CFR Part 820) and that, through periodic GMP inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

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).(b)
