• Record ID: K970145
• Device Name: PERINEOMETER & VAGINAL PROBE (BIOFEEDBACK MONITOR #20 AND VAGINAL PROBE)
• Applicant: Biosearch Medical Products, Inc.
• Product Code: HIR · Obstetrics/Gynecology
• Decision Date: Aug 11, 1997
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 884.1425
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The Perineometer (Biofeedback monitor) and vaginal probe are intended to be used to assist the patient in exercising her pelvic muscles (referred to Kegal exercises) which in the majority of cases lead to increased bladder control.

Device Story

Device consists of a vaginal probe connected to a battery-powered biofeedback monitor. Probe features a silicone shaft and inflatable silicone balloon; balloon provides gentle pressure to vaginal wall. Patient performs Kegel exercises; pelvic muscle contractions displace air within the balloon. Pressure changes are transmitted via tubing to the monitor, which converts signals into a visual display of LED lights. Used in a clinical or home setting under physician prescription. Provides real-time visual feedback of muscle activity, assisting patients in monitoring exercise progress. Benefits include enhanced pelvic floor strength and improved urinary continence.

Clinical Evidence

Bench testing only. Biocompatibility testing performed on probe components including cytotoxicity (MEM elution), hemolysis, pyrogenicity, intracutaneous toxicity, and implantation tests. All materials met USP Class VI requirements. Check valve performance verified against ANSI/HIMA MD 70.1 and British BS 5081 standards.

Technological Characteristics

Passive biofeedback system. Materials: USP Class VI silicone (probe/marker ring), medical-grade plastic (tubing/connectors). Sensing principle: pneumatic pressure displacement via inflatable balloon. Energy source: rechargeable batteries (unit disabled during charging). Connectivity: wired pneumatic connection between probe and monitor. Output: LED visual display. Sterilization: not specified.

Indications for Use

Indicated for female patients requiring pelvic muscle exercise (Kegel exercises) to improve pelvic floor strength and bladder control, typically associated with anatomical or neurological pelvic floor dysfunction.

Regulatory Classification

Identification

A perineometer is a device consisting of a fluid-filled sack for intravaginal use that is attached to an external manometer. The devices measure the strength of the perineal muscles by offering resistence to a patient's voluntary contractions of these muscles and is used to diagnose and to correct, through exercise, uninary incontinence or sexual dysfunction.

### PERINEOMETER & VAGINAL PROBE

## DESCRIPTION OF THE DEVICE:

The PERINEOMETER & VAGINAL PROBE, is a passive device which will allow the patient to visually monitor their Kegal exercise progress.

The **Vaginal probe** is a Single patient use only device comprised of a medical grade Silicone shaft with a silicone balloon (Inflatable to enlarge to accomodate various vaginal sizes.) and a polyurethane connector tube. The silicone balloon is mounted in such a way that when pressure is applied to it, air will be displaced through its connector tubing. This air displacement is being monitored by the biofeedback monitor which will cause the LED lights to turn on in proportion to the pressure exerted. This probe is similar to the legally marketed probe via 510(k) numbers (k902843) and (k913736) except that in this case we are inflating the balloon to provide gentle pressure to the vaginal wall. This will allow the probe to be customized for the patients individual vaginal size.

The **Perineometer (Biofeedback Monitor)** is powered by rechargeable batteries. To prevent a potential shock hazard this unit will not function while it is being recharged. The Perineometer is identical to the biofeedback monitor which had been 510(k) approved for use in fecal incontinence (k902843). Thus, in the case of this 510(k) submission, we only seek to expand its use for general Kegal exercises.

## SYSTEM DESCRIPTION:

The patient inserts the vaginal probe which is connected to the Perineometer. Once the probe is inserted the balloon is inflated until it provides gentle pressure to the vaginal wall. As the pelvic muscles expand and contract (Kegal exercises) the pressure in the probe changes and these pressure changes are converted into a visual signal on the Perineometer (biofeedback monitor). The visual signal on the Perineometer is a series of LEDs (lights) which provide the patient with a real time representation of pelvic muscle activity.

# SAFETY & EFFECTIVENESS SUMMARY
## Biosearch Medical Products, Inc.
### PERINEOMETER & VAGINAL PROBE

**Why do pelvic muscle exercises (Kegal exercise):** Without the strength and support of the pelvic floor muscles, urinary continence is difficult to maintain. Female urinary incontinence is usually associated with anatomical, neurological pelvic floor dysfunction. Presently many Urologist/Gynecologists are recommending pelvic muscle exercises to their female patients since these exercises will serve to enhance the strength and pelvic muscle control for the patient and in many cases improve urinary continence.

**What need does this device address:** The Perineometer (Biofeedback Monitor) and Vaginal Probe makes it possible for the patient to visualize their pelvic muscle activity. This is otherwise extremely difficult for the patient to monitor, due to the anatomical location of these muscles. This procedure must be performed at regular intervals as prescribed by the physician.

Dear Mr. Dyck:

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 Current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS 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.
