Abstract: An occlusive medical device system may include a microcatheter, an elongate shaft, an occlusive medical device, wherein a release wire is configured to releasably attach the medical device to the distal end of the shaft at a release mechanism, and an RF generator. In a first electrical state current is not flowing and in a second electrical state current is flowing to the medical device. The shaft is slidable between a first position wherein the medical device is disposed within the microcatheter, a second position wherein at least a portion of the medical device is disposed outside of the microcatheter and the release mechanism is disposed within the microcatheter, and a third position wherein the release mechanism is disposed outside of the microcatheter. The medical device system is configured to be in the second electrical state when the elongate shaft is in the second position.

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.
