Microthermx Microwave Ablation System Models Mtx-180 or Mtx

FDA-Cleared Indications

• Ablation of soft-tissue tumors using microwave energy.
• Use with compatible microwave ablation accessories and imaging guidance for targeting and treating tumor tissue.

Clinical Applications

• Image-guided microwave ablation of selected soft-tissue tumors.
• Percutaneous tumor ablation performed under CT or ultrasound guidance when the patient and tumor are appropriate candidates.
• Thermal destruction of tumor tissue as an alternative to surgical resection in selected cases.

Reported off-label uses

• Microwave ablation of selected liver tumors when the specific use, tumor characteristics, or treatment plan falls outside the device labeling.
• Microwave ablation of selected lung, kidney, or bone tumors when those applications are not specifically covered by the device labeling.

Off-label use: these uses are reported in practice or the literature but are not part of the FDA-cleared indications. Physicians may use a cleared device off-label based on their medical judgment; the manufacturer may not promote off-label uses.

Practical Considerations

• The system includes models such as the MTX-180 or MTX and requires compatible microwave antennas and accessories; available antenna sizes and configurations should be confirmed in the current labeling.
• Treatment is typically performed with CT or ultrasound guidance, depending on tumor location and visibility.
• Microwave ablation generates heat and requires attention to nearby organs, vessels, nerves, skin, and implanted devices.
• MRI compatibility should not be assumed. The generator, antenna, cables, and accessories require review of the current manufacturer labeling before MRI use or treatment in an MRI environment.
• Contraindications and precautions depend on tumor location, bleeding risk, infection, nearby critical structures, implanted devices, and the patient's overall condition.
