Abstract: A method for cooling a medical device includes fluidly connecting a cooling fluid reservoir to a medical device. The fluid connection includes a fluid out-flow path and a fluid return path corresponding to the fluid reservoir. The cooling fluid is pumped from the fluid reservoir to the medical device. The medical device is energized and the heat generated by the energization is absorbed by the cooling fluid pumped to the medical device. The cooling fluid is received at the reservoir containing the absorbed heat. The cooling fluid transfers the absorbed heat to the cooling fluid in the reservoir and to the environment adjacent to the reservoir.

Abstract: A method for treating tissue through a branched luminal network of a patient is provided. A pathway to a point of interest in branched luminal network of a patient is generated. An extended working channel is advanced transorally into the branched luminal network and along the pathway to the point of interest. The extended working channel may be positioned in a substantially fixed orientation at the point interest. A tool is advanced though the extended working channel to the point of interest. Tissue at the point of interest is treated.

Abstract: A system includes a treatment probe, a first tracking sensor configured to track a location of the treatment probe, an ultrasound imager, a second tracking sensor configured to track a location of the ultrasound imager, and a tracking system. The ultrasound imager generates real-time ultrasound images. The tracking system receives location information from the first and second tracking sensors, tracks the location of the treatment probe and the location of the ultrasound imager, and displays the real-time ultrasound images and a representation of the treatment probe in one or more pre-stored images.

Abstract: A microwave ablation catheter is provided. The microwave ablation catheter includes a coaxial cable connected at its proximal end to a microwave energy source and at its distal end to a distal radiating section. The coaxial cable includes inner and outer conductors and a dielectric positioned therebetween. The inner conductor extends distally past the outer conductor and is in sealed engagement with the distal radiating section. A balun is formed in part from a conductive material electrically connected to the outer conductor of the coaxial cable and extends along at least a portion of the coaxial cable. The conductive material has a braided configuration and is covered by at least one insulative material.
