Not Found

No
The summary describes a standard electrosurgical generator for thermal coagulation and contains no mention of AI, ML, image processing, or data sets typically associated with AI/ML device submissions.

Yes
The device is intended for the thermal coagulation of soft tissues, which is a therapeutic intervention.

No
The device is described as an electrosurgical generator for thermal coagulation of soft tissues, which is a therapeutic function, not a diagnostic one.

No

The device is described as an "RF Generator," which is a hardware component used in electrosurgery. The description of its intended use with "separately approved electrodes" further indicates a physical device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is "thermal coagulation of soft tissues" using an electrosurgical generator. This is a therapeutic procedure performed directly on the patient's body.
  • IVD Definition: In Vitro Diagnostics (IVDs) are devices used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information about a person's health. They are used outside the body (in vitro).

This device operates on the body for treatment, not on specimens for diagnosis.

Dear Mr. Nichols:

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 (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 regulation (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.
