Abstract
An introducer set for a microwave ablation probe is disclosed. The introducer set includes a cannula that is at least partially transparent to microwave energy, and a stylet sized to be received by the lumen of the cannula. Other examples provide a microwave ablation system including a microwave ablation probe having a radiating portion and a cannula that is at least partially transparent to microwave energy. The radiating portion of the probe aligns with the transparent portion of the cannula when the probe is inserted into the cannula lumen. The technology provides a method including introducing a microwave ablation probe into the lumen of a cannula having a cannula body that is at least partially transparent to microwave energy, aligning the transparent portion of the cannula with the radiating portion of the probe, and causing microwave energy to be emitted from the radiating portion of the probe.
