The description focuses on controlled delivery of RF energy based on pre-set parameters (temperature, power, energy, time) and real-time impedance/temperature monitoring, without mentioning adaptive learning or data-driven decision making characteristic of AI/ML. The "Mentions AI, DNN, or ML" section is explicitly marked as "Not Found".
Yes
The device is indicated for "coagulation of tissue," which implies it is used for treatment.
No
Explanation: The device is described as an electrosurgical generator designed for "coagulation of tissue" and "localized tissue coagulation." Its function is therapeutic (treating tissue by coagulation), not diagnostic (identifying or assessing a medical condition).
No
The device description explicitly states it is an "electrosurgical generator" with hardware components like controls, readouts, connectors, a foot pedal, and an integrated fluid pump. It is not solely software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "coagulation of tissue" using radiofrequency energy. This is a therapeutic procedure performed directly on the patient's tissue.
- Device Description: The device is an "electrosurgical generator" designed to deliver energy for "localized tissue coagulation." This describes a device used for surgical or therapeutic intervention.
- Lack of IVD Characteristics: An IVD device is used to examine specimens (like blood, urine, or tissue samples) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening. This device does not perform any such analysis of specimens.
Therefore, the Stretta Control Module Model S400 is a therapeutic medical device, not an in vitro diagnostic device.

Device Description
The Stretta Control Module Model S400 is an electrosurgical generator that is designed to deliver controlled low level radiofrequency energy for localized tissue coagulation. The Stretta generator has controls for maximum temperature, power delivered, energy delivered and time of energy delivered. The unit has readout for total energy delivered, impedance, maximum power and temperature for up to six channels. Connectors located on the front panel include electrode connectors and a foot pedal. A fluid pump is integrated into the Stretta generator to deliver cooling fluid to the surrounding tissue adjacent to the electrode.
System accessories include an AC power cord, a single-pedal footswitch and a connecting cable.

Dear Dr.Wehman :
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 requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (OS) 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.
