## Indications for Use

The Family of Micro Electrode Instruments are intended for use in laparoscopic minimally invasive surgical procedures to provide monopolar electrocautery capability to dissect and coagulate tissue. Federal law (U.S.A.) restricts this device to sale by or on the order of a physician.

## Device Story

Micro Electrode Instruments are surgical tools used in laparoscopic procedures. They provide monopolar electrocautery capability for tissue dissection and coagulation. The device is operated by a physician during minimally invasive surgery. It requires connection to an external electrosurgical generator, cables, and a patient grounding plate. The physician activates the generator while the instrument is in contact with or adjacent to the target tissue to perform the procedure. The device benefits patients by enabling precise tissue management during minimally invasive surgery. Safety relies on maintaining insulation integrity to prevent current leakage.

## Clinical Evidence

Bench testing only. Dielectric insulation testing performed at 3000V using a 100% sampling plan.

## Technological Characteristics

Materials: Stainless steel and polyvinylidene fluoride. Energy source: External electrosurgical generator (monopolar). Connectivity: Requires connection to electrosurgical unit, cables, and patient grounding plate. Sterilization: Reusable, validated to achieve a Sterility Assurance Level (SAL) of 10^-6.

## Regulatory Identification

A unipolar endoscopic coagulator-cutter is a device designed to destroy tissue with high temperatures by directing a high frequency electrical current through the tissue between an energized probe and a grounding plate. It is used in female sterilization and in other operative procedures under endoscopic observation. This generic type of device may include the following accessories: an electrical generator, probes and electrical cables, and a patient grounding plate. This generic type of device does not include devices used to perform female sterilization under hysteroscopic observation.

## Predicate Devices

- Gynescope Electrodes

#### SUMMARY OF SAFETY AND EFFECTIVENESS MICRO ELECTRODE INSTRUMENTS NOV - 5 1997

The Summary of Safety and Effectiveness on Micro Elects data available and presented at the time the submission was prepared, but caution should be exercised in interpreting the data. The results of future studies may require alterations of the conclusions or recommendations set forth.

## Intended Use

The Family of Micro Electrode Instruments are intended for use in laparoscopic minimally invasive surgical procedures to provide monopolar electrocautery capability to dissect and coagulate tissue.

### Indications

The incorporation of monopolar electrocautery capability within the instrument provides for cutting and coagulating of intended target tissue sites.

### Warning

Do not use any instrument that exhibits insulation degradation. Any damage of the insulation such as dents, scratches, cracking or splitting may allow electric current leakage and cause shock to the patient or doctor.

### Caution

Federal law (U.S.A.) restricts this device to sale by or on the order of a physician.

### Precaution

The user should take precautions to ensure that all minimally invasive components including laparoscope, endoscope, forceps, trocars and sleeves, electrocautery units, cables, and patient grounding plate are compatible and intended for minimally invasive surgery. It is imperative that all electrosurgical instruments be in contact with or next to the tissue or target prior to activation of the generator to eliminate the possibility of voltage/current seeking an exit through the insulation to the closet "ground". Activate generator only when instrument is in position.

# Bench Test

Dielectric Insulation Test @ 3000V - 100% sampling plan.

## Substantial Equivalency Information

The Family of Micro Electrode Instruments are similar to the Gynescope Electrodes

|           | - Gynescope Electrodes                     | Micro Electrodes                           |
|-----------|--------------------------------------------|--------------------------------------------|
| Materials | Stainless Steel<br>Polyvinylidene fluoride | Stainless Steel<br>Polyvinylidene fluoride |

The Micro Electrodes are intended for reuse and following the Cleaning and Sterilization Instructions, sterilization will obtain a Sterility Assurance Level (SAL) of 106.

The intended use and technological characteristics of these devices do not vary significantly. The safety and effectiveness of the Family of Micro Electrodes are comparable to that of the Gynescope Electrodes.

Re: K971838

Micro Electrodes Dated: October 6, 1997 Received: October 7, 1997 Regulatory class: II 21 CFR §884.4160/Product code: 85 KNF

Dear Ms. Pekar:

We have reviewed your Section 510(k) notification of intent to market the device 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 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 (OS) 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. 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 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.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4613.
