THE NORTECH GAS WARMING UNIT IS INDICATED FOR WARMING GAS (95-1069F / 35-41℃) USED FOR THE DISTENTION OF THE ABDOMEN FOR DIAGNOSTIC AND / OR OPERATIVE LAPAROSCOPY.
The CO2 Gas Warming Unit is designed to be used in conjunction with an insufflator to provide continuous non-adiustable heating of gas to a laparoscopic instrument. The CO2 Gas Warming Unit is comprised of a control unit and heat exchanger(available as disposable or re-usable) and power cords.
This document describes the Nortech CO2 Gas Warming Unit, which is a medical device designed to warm CO2 gas used during laparoscopic procedures. The provided content is a summary of safety and effectiveness, an FDA clearance letter, and the indications for use. It is a 510(k) submission, meaning it aims to demonstrate substantial equivalence to a predicate device rather than undergoing a de novo approval process based on novel safety and effectiveness studies.
As such, the information typically found for novel device approvals regarding acceptance criteria, performance studies with specific statistical metrics (like sensitivity, specificity, AUC), training/test set details, ground truth establishment, and MRMC studies, is not present in the provided text. The FDA 510(k) process primarily relies on demonstrating that the new device is as safe and effective as a legally marketed predicate device.
Therefore, I cannot fulfill all parts of your request as the information is not contained within the provided document.
Here's an analysis based on the available information:
1. A table of acceptance criteria and the reported device performance
The document does not explicitly state acceptance criteria or report performance in terms of statistical efficacy metrics (e.g., sensitivity, specificity, accuracy) like a new diagnostic or prognostic device would. Instead, the submission focuses on demonstrating substantial equivalence to existing devices.
The "Indications For Use" section provides the desired operating range for the device's primary function:
- Acceptance Criteria (Implicit from Indications For Use): The device should warm gas to a temperature range of 95-106°F / 35-41°C.
- Reported Device Performance: The document states, "THE NORTECH GAS WARMING UNIT IS INDICATED FOR WARMING GAS (95-106°F / 35-41°C)..." This implies that the device is designed and demonstrated to operate within this range, meeting its intended function. However, no specific performance data from a clinical trial or bench test is provided in this summary.
2. Sample size used for the test set and the data provenance
Not applicable. This is a 510(k) submission for a physical device, not an AI or diagnostic algorithm that would typically involve a test set of data/images. The "studies" for such a device would likely involve engineering verification and validation tests (e.g., temperature accuracy, flow rate stability, durability) rather than a clinical dataset. The document does not provide details of such tests.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable. As noted above, this is a physical medical device, not a diagnostic or AI system requiring expert-adjudicated ground truth.
4. Adjudication method for the test set
Not applicable.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
Not applicable. This device does not involve human readers or AI assistance.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
Not applicable. This is not an algorithm.
7. The type of ground truth used
Not applicable in the context of diagnostic performance. For a device like this, ground truth would refer to accurately measured physical parameters (e.g., gas temperature measured by a calibrated thermometer). The document implicitly suggests that the device's output temperature would be compared against these calibrated measurements to ensure it falls within the specified range.
8. The sample size for the training set
Not applicable. This is not a machine learning model.
9. How the ground truth for the training set was established
Not applicable.

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 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 (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 (OS) for Medical Devices: General regulation (2) 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 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.
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. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation i entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers Assistance at its toll-free number (800) 638-2041 or (301) 443-6597 or at its Internet address "http://www.fda.gov/cdrb/dsmaldsmamain.html".
