No
The device description and intended use focus on radio-frequency energy delivery and control based on temperature, impedance, power, and waveform. There is no mention of AI, ML, image processing, or data sets for training or testing.
Yes
The device is indicated for ablation, coagulation, and hemostasis of soft tissue and blood vessels in various surgical procedures, which are therapeutic interventions aimed at treating conditions or diseases.
No
The document describes the Gyrus ENT G II RF Workstation as a combination of two radio-frequency generators intended for surgical procedures involving ablation, coagulation, and hemostasis of soft tissue in otorhinolaryngology. Its primary function is therapeutic and surgical, not diagnostic. While it has readouts for parameters like temperature, impedance, energy, and time, these are for monitoring and controlling the therapeutic delivery of energy, not for diagnosing a medical condition.
No
The device description clearly states it is a "combination of two previously cleared radio-frequency generators" and describes hardware components like controls, readouts, connectors, and a foot pedal. It also mentions accessories like electrodes and cables. This indicates it is a hardware device with associated software for control and operation, not a software-only medical device.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- Intended Use: The intended use clearly describes the device's function as a surgical tool for ablation, coagulation, and hemostasis of soft tissue and blood vessels within the body during ENT procedures. This is an in vivo application.
- Device Description: The description details a radio-frequency generator and associated electrodes/instruments used for applying energy directly to tissue. This is consistent with a surgical device, not a device that analyzes samples outside the body.
- Lack of IVD Characteristics: There is no mention of the device being used to test or analyze biological samples (blood, urine, tissue samples, etc.) in vitro (outside the living body). The device's purpose is to directly interact with and modify tissue within the patient.
Therefore, the Gyrus ENT G II RF Workstation is a surgical device, not an In Vitro Diagnostic.
