AI/ML Overview

The provided document is a 510(k) Safety Summary for a medical device called the "Stellartech Coagulation System." This type of document is submitted to the FDA to demonstrate that a new device is substantially equivalent to a legally marketed predicate device.

It's important to understand that a 510(k) submission primarily focuses on demonstrating "substantial equivalence" of a new device to existing predicate devices, rather than establishing acceptance criteria through new clinical studies measuring performance against specific metrics.

Therefore, the document does not contain information about:

  • A table of acceptance criteria and reported device performance directly derived from a new study specific to this submission.
  • Sample sizes used for a test set, data provenance, or the number/qualifications of experts for ground truth establishment.
  • Adjudication methods, MRMC comparative effectiveness studies, or standalone algorithm performance studies.
  • Training set sample sizes or how their ground truth was established.

Instead, the document asserts substantial equivalence based on prior predicate devices and their established safety and effectiveness.

Here's what the document does provide and why the requested information is not present:

  1. A table of acceptance criteria and the reported device performance:

    • N/A. The document does not present specific acceptance criteria in the form of performance metrics (like sensitivity, specificity, accuracy, etc.) and then report the device's measured performance against those criteria. The acceptance criterion for a 510(k) is "substantial equivalence" to a predicate device. The "performance" demonstrated is that its technical characteristics, principles of operation, materials, and intended use are comparable to legally marketed predicate devices.
  2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):

    • N/A. No new clinical or test set data is presented in this 510(k) summary for performance evaluation against specific metrics. The substantial equivalence argument relies on the inherent safety and effectiveness of the predicate devices.
  3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience):

    • N/A. As no new test set is described, there's no mention of experts for establishing ground truth.
  4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

    • N/A. No test set described.
  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:

    • N/A. This device (Electrosurgical Unit) is not an AI/imaging diagnostic device, and no MRMC study or AI assistance is mentioned.
  6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

    • N/A. This is not an algorithmic device.
  7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

    • N/A. As no new performance study is detailed, no ground truth types are described. The "ground truth" in a 510(k) for substantial equivalence is the safety and effectiveness of the legally marketed predicate devices.
  8. The sample size for the training set:

    • N/A. This is not an AI/machine learning device that requires a training set.
  9. How the ground truth for the training set was established:

    • N/A. Not applicable, as it's not an AI/machine learning device.

In summary: The provided document is a 510(k) submission, which aims to demonstrate "substantial equivalence" to existing devices, not to present novel clinical study data with specific acceptance criteria and performance metrics. The information requested (acceptance criteria, study details, sample sizes, ground truth methods, MRMC studies, etc.) is typically found in PMA (Premarket Approval) applications or clinical studies for novel devices, not generally in 510(k) summaries like this one.

Dear Mr. Santos:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and 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) that do not require approval of a premarket approval application (PMA). 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 (PMA), 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 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the

quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050. This letter will allow you to begin marketing your device as described in your Section 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), please contact the Office of Compliance at (301) 594-4659. 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 entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (301) 443-6597 or at its Internet address http://www.fda.gov/cdrh/dsma/dsmamain.html
