Valleylab Microwave Ablation Generator
Covidien Lp, Formerly Know As Valleylab, A Divison
FDA Clearance Information
The Valleylab Microwave Ablation Generator was cleared by the FDA through the 510k pathway on November 25, 2008. It is manufactured by Covidien Lp and classified as a Class 2 device.
What It Is
FDA-Cleared Indications
- Use in conjunction with compatible microwave ablation accessories for the coagulation or ablation of soft tissue.
- Use during procedures intended to destroy targeted tumor tissue under appropriate clinical and imaging guidance.
Clinical Applications
- Image-guided microwave ablation of liver tumors.
- Percutaneous, laparoscopic, or surgical microwave ablation of selected solid tumors when used with compatible accessories.
- Local tumor ablation when surgical resection is not feasible or is not the selected treatment.
- Microwave ablation performed as part of a multidisciplinary cancer treatment plan.
Reported off-label uses
- Microwave ablation of selected renal tumors.
- Microwave ablation of selected lung tumors.
- Microwave ablation of selected bone or adrenal tumors.
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 generator must be used with compatible microwave ablation antennas, cables, and accessories specified by the manufacturer; the generator alone does not perform tissue ablation.
- Ablation size depends on antenna design, power, treatment duration, tissue characteristics, and the distance between the antenna and nearby organs or critical structures.
- Treatment is typically planned and monitored with imaging such as ultrasound, computed tomography, or magnetic resonance imaging, depending on the procedure and institutional protocol.
- The generator and connected accessories should not be assumed to be MRI safe or conditional without verification of the exact system configuration and labeling.
- Potential contraindications and precautions include inability to safely access the target, uncorrected bleeding risk, active infection, and risk of thermal injury to adjacent organs, nerves, skin, or major vessels.
