## Indications for Use

The Nortech CO2 Gas Warmer II Unit shall be used as a means of supplying warm gas for the distention of the abdomen for diagnostic and/or operative laparoscopy.

## Device Story

CO2 Gas Warmer II is a laparoscopic accessory used to heat insufflation gas. System consists of a control unit, reusable heat exchanger, and power cords. Device connects to an insufflator to provide continuous, non-adjustable heating of CO2 gas to a target range of 35-40.5°C. Used in clinical settings (OR) by physicians during laparoscopic procedures to maintain patient body temperature and reduce potential thermal shock from cold gas. Output is warmed gas delivered to the abdominal cavity. Benefits include improved patient comfort and potential reduction in hypothermia risks during surgery.

## Clinical Evidence

No clinical data provided; substantial equivalence is based on design and material characteristics.

## Technological Characteristics

System comprises a control unit and reusable heat exchanger. Materials are non-toxic and previously used in medical devices. Provides continuous, non-adjustable heating of gas to 35-40.5°C. Powered by electrical cords.

## Regulatory Identification

A laparoscopic insufflator is a device used to facilitate the use of the laparoscope by filling the peritoneal cavity with gas to distend it.

## Reference Devices

- Snoden Pencer (similar device)
- Wisap (similar device)

Re: K992381 CO2 Gas Warmer II Dated: August 16, 1999 Received: August 19, 1999 Requiatory Class: Il 21 CFR §884.1730/Procode: 85 HIF

Dear Mr. Kurek:

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 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 (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 requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General requlation (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 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.
