No
The description focuses on the delivery of microwave energy with operator-selected parameters and image guidance, without mentioning any AI/ML components for decision-making, image analysis, or parameter optimization.

Yes
The device is described as delivering microwave energy for coagulation (ablation) of soft tissue, specifically mentioned for the treatment of non-resectable liver tumors. This indicates its use in a therapeutic capacity to treat a medical condition.

No

This device is designed for therapeutic ablation of soft tissue, not for diagnosis. While it uses "image guidance," this is for targeting the ablation, not for diagnostic purposes.

No

The device description clearly outlines hardware components including a generator, pump, mobile cart/tabletop stand, antennas, cooling circuit, and temperature sensors.

Based on the provided information, the MicroThermX Microwave Ablation System (MTX) is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
  • MTX Function: The MTX system delivers microwave energy to directly ablate (destroy) soft tissue within the body. It is a therapeutic device used for treatment, not a diagnostic test performed on a sample outside the body.
  • Intended Use: The intended use clearly states "coagulation (ablation) of soft tissue" and "partial or complete ablation of non-resectable liver tumors." This is a treatment procedure.
  • Device Description: The description details a generator, pump, antennas, and cooling circuit, all components of a system designed to deliver energy for tissue destruction in vivo.
  • Lack of Diagnostic Elements: There is no mention of analyzing biological samples, detecting biomarkers, or providing diagnostic information based on laboratory analysis.

Therefore, the MicroThermX Microwave Ablation System is a therapeutic medical device, not an in vitro diagnostic device.
