Oligio X is a radio frequency therapy system. The radio frequency output of the device is 6.78 MHz, and the maximum power is 200 W. Oligio X consists of a main body including touch LCD monitor, a RF handpiece, return pads, a return pad cable, non-sterile treatment tips, cooling fluids, footswitch and a power cable. Oligio X RF System delivers radio frequency energy for selective coagulation of tissue while conductively cooling the epidermis. Oligio X delivers energy form the disposable tip to the patient, and employs radio frequency turning to provide radio frequency energy across a range of impedances for delivery to the patient through the tip.

AI/ML Overview

The provided text does not contain information about a study proving the device meets acceptance criteria in the context of a clinical performance study with human subjects, expert adjudication, or ground truth establishment as would be typical for an AI/software-as-a-medical-device (SaMD) submission.

Instead, the document is a 510(k) premarket notification for a physical medical device, the "Oligio X," which is a radio frequency therapy system for dermatologic and general surgical procedures. The substantial equivalence determination is based on comparisons to a predicate device and non-clinical testing, primarily focused on electrical safety, electromagnetic compatibility, software validation, and biocompatibility.

Specifically, the document states: "No clinical studies were considered necessary and performed." This indicates that for this particular device submission, a clinical performance study (which would typically involve the elements you've asked about, such as ground truth, experts, and human-in-the-loop performance) was not required by the FDA.

Therefore, I cannot populate the table or answer the specific questions related to a clinical study and AI performance, as that information is not present in the provided text.

However, I can extract the "performance testing" details that were reported from non-clinical bench tests:

Acceptance Criteria and Reported Device Performance (Non-Clinical Bench Tests)

Acceptance Criteria	Reported Device Performance
RF output frequency	6.78MHz ± 1%
Max output power	140 W
Handpiece vibration	Low (30dB), Medium (40dB), High (50dB)

For the rest of your questions, based on the provided text:

Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective): Not applicable. No clinical test set or human data is mentioned. The "test set" for the reported performance was likely conducted on the device itself as part of bench testing.
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): Not applicable. No expert review or ground truth establishment for a test set (involving clinical data) was performed or mentioned.
Adjudication method (e.g., 2+1, 3+1, none) for the test set: Not applicable.
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 is not an AI/SaMD product that assists human readers.
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 (expert consensus, pathology, outcomes data, etc): Not applicable.
The sample size for the training set: Not applicable. This device does not use a training set for machine learning.
How the ground truth for the training set was established: Not applicable.

Dear Hyun Sik Yoon:

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 (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 available 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.

{1}------------------------------------------------

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30. Design controls; 21 CFR 820.90. Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).

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); medical device reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 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 (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.

All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule").
