The description focuses on the hardware components and basic user settings (time and power) for energy delivery, with no mention of AI/ML terms or functionalities like image analysis or automated parameter adjustments based on data.
Yes
Explanation: The device is intended for coagulation (ablation) of soft tissue, which is a therapeutic intervention to treat conditions affecting soft tissue.
No
Explanation: The device is described as an ablation system intended for coagulation of soft tissue, delivering energy to ablate tissue. It is not mentioned to be used for identifying or diagnosing a condition.
No
The device description explicitly lists hardware components such as a generator, electrode kits, temperature probe, and foot switch, indicating it is a hardware-based system with software control.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "coagulation (ablation) of soft tissue." This is a therapeutic procedure performed on the patient's body, not a test performed on a sample taken from the patient's body.
- Device Description: The description details a system that delivers energy into soft tissue for ablation. This is consistent with a therapeutic device, not a diagnostic one that analyzes samples.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue samples, etc.), detecting specific analytes, or providing diagnostic information based on laboratory testing.
IVD devices are designed to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device's function is to treat tissue directly.

Device Description
The Microwave Ablation System M150E is microwave-based system intended to deliver energy through an antenna inserted into soft tissue for the purpose of coagulating (ablatlng) a defined volume of that tissue. The Microwave Ablation System utilizes a 2450MHz generator to deliver power to single microwave ablation antenna or double microwave ablation antennas. The Microwave Ablation Generator provides for user setting of ablation time and ablation power.
The proposed device consists of Microwave Ablation Generator, Microwave Ablation Electrode Kits, Temperature Probe and Foot Switch. Wherein, The Microwave Ablation Electrode Kits consists of Microwave Ablation Antenna, water pipe and Coax cable, to be used for puncturing the patient's lesion position during operation and also for outputting microwave energy to ablate the tumor tissue through connection with Microwave Ablation Generator. The Temperature Probe is applied to monitor the temperature of the target location and to protect important organs and tissues in the periphery of the lesion from unexpected damage by microwave energy.
It supports both power and temperature modes.
Power mode
Under the power mode, at the beginning, the system output microwave power according manually setting. When the tissue temperature reaches the target temperature, the system adjusts the duty cycle in real time according to the specific algorithm and load power to keep the tissue temperature on the target temperature. Two microwave ablation antennas can be used for microwave ablation.
Temperature mode
Under the temperature mode, at the beginning, the system output microwave power according manually setting. When the tissue temperature reaches the target temperature, the system adjusts the output of microwave power in real time according to the specific algorithm to keep the tissue temperature on the target temperature. Two microwave ablation antennas can be used for microwave ablation.
The Microwave Ablation Generator is non-sterile, while Microwave Ablation Electrode Kits and Temperature Probe are sterile.
The device is software-driven and the software validation is provided in Section of Software.

3.8 Determination of substantial equivalence
The proposed device is equivalent with respect to the basic system design and function to that of the predicate device. The proposed device isn't the implants and high-risk device. And it doesn't have new intended purposes, new medical, new target populations, and new users and so on. What's more, it can't use the medicinal substances or animal tissues. So differences between the predicate and proposed device do not raise new questions of safety or effectiveness.
