AGNES is indicated for use in dermatological and general surgical procedures for electrocoagulation and hemostasis.
AGNES is a RF electrosurgical device. It consists of LCD screen, radiofrequency generator and SMPS. The accessories are a footswitch, a hand-piece, single use needle type RF electrodes and FDA cleared Disposable neutral electrode pad (K102372).
This document, K203013, is a 510(k) summary for a medical device called AGNES, an RF electrosurgical device. It's a submission to the FDA to demonstrate substantial equivalence to a previously cleared device (K192728).
The document details changes made to the device and the testing performed to ensure safety and effectiveness. However, it does not contain any information regarding acceptance criteria or a study proving the device meets those criteria in the context of human clinical performance or AI algorithm performance. This is because K203013 is for an electrosurgical device, not an AI or imaging device that would typically have performance metrics like sensitivity, specificity, or reader improvement.
The tests performed are primarily bench tests, animal studies, and biocompatibility tests related to the physical changes made to the device (e.g., power input, connector color, and a new type of RF electrode). Therefore, I cannot fulfill your request for information on acceptance criteria and a study proving performance in the way you've outlined for an AI/imaging device.
To directly address your specific points, based on the provided document:
-
A table of acceptance criteria and the reported device performance: This document does not provide a table of acceptance criteria for clinical performance (e.g., sensitivity, specificity, accuracy) because it's not evaluating an AI or diagnostic imaging device in that manner. The "performance" discussed relates to electrical safety, electromagnetic compatibility, and thermal effects, for which the acceptance is successful compliance with recognized standards.
-
Sample size used for the test set and the data provenance:
- Bench Testing (Electrical Safety, EMC): These tests are typically performed on a sample of the manufactured device and new accessories. Sample size is not specified but would follow standard engineering testing practices for medical devices, often a small number of units.
- Biocompatibility Testing: Tested on materials of manufacture and the final device. Sample size not specified.
- Animal Testing: Conducted on tissues from 3 mini pigs for thermal tissue damage/spread, and skin from 1 mini pig for histopathological analysis.
- Data Provenance: Not explicitly stated for specific test data, but the submitter is Agnes Medical CO., LTD in South Korea.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. The "ground truth" for this device's performance is established by compliance with engineering and biological safety standards (e.g., IEC standards, ISO standards for biocompatibility), not through expert consensus on diagnostic interpretations. For the animal study, histopathological analysis would be performed by a qualified pathologist, but the number and qualifications are not specified.
-
Adjudication method for the test set: Not applicable. There's no human interpretation or diagnostic decision-making being assessed by multiple readers that would require adjudication.
-
If a multi-reader, multi-case (MRMC) comparative effectiveness study was done: No. This is not an AI or diagnostic imaging device; therefore, an MRMC study is not relevant.
-
If a standalone (i.e. algorithm only without human-in-the loop performance) was done: Not applicable. This is not an AI algorithm.
-
The type of ground truth used:
- Bench Testing: Engineering specifications and compliance with international standards (e.g., IEC 60601-1, IEC 60601-2-2, IEC 60601-1-2).
- Biocompatibility: Compliance with ISO 10993 series standards.
- Animal Testing: Histopathological analysis of tissue and thermal imaging measurements.
-
The sample size for the training set: Not applicable. This document does not describe an AI/ML device that requires a training set.
-
How the ground truth for the training set was established: Not applicable.
In summary, the provided document pertains to the regulatory clearance of an electrosurgical device based on engineering and biological safety standards, not an AI or diagnostic imaging device involving clinical performance metrics and reader studies.

Dear DongHa Lee:
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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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
{1}------------------------------------------------
requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

11. Performance Testing - Animal Testing
Animal study was performed to assess thermal tissue damage/spread using mini pig tissues. The skin, liver, kidney, and femoral muscle dissected from 3 mini pigs were used for thermal tissue spread experiment. The skin from 1 mini pig was used in the histopathological analysis for thermal tissue damage experiment. Thermal imaging area analysis, the maximum temperature, the time to reach basal temperature, and histopathological analysis were evaluated.
12. Conclusion
The major consideration such as intended use and principle of operation is not changed. The changes (modifications) of the device were verified and validated relevant to electrical safety and electromagnetic compatibility and biocompatibility. Animal test also performed to assess thermal effect. The test results are supported that the device still maintain safety and effectiveness.
We conclude that the modified device is substantially equivalent to the legally marketed (existed) device.
