    Abstract: A microwave ablation system is presented including a microwave applicator having an antenna configured to deliver microwave energy and a microwave generator coupled to the microwave applicator and configured to generate a microwave signal and transmit the microwave signal to the antenna. The microwave ablation system further includes a radiometer configured to measure emissions from a thermal field created when the microwave applicator delivers microwave energy, the thermal field providing in-situ quantitative information of a material in the thermal field. The quantitative information is used to automatically adjust power transmission and time settings of the microwave generator to compensate for different thermal environments.

    Abstract: A system for ultrasound interrogation of a lung includes a memory, an electromagnetic (EM) board, an extended working channel (EWC), an EM sensor, a US transducer, and a processor. The memory stores a three dimensional (3D) model, a pathway plan for navigating a luminal network. An EM board generates an EM field. The EWC is configured to navigate the luminal network of a patient toward a target following the pathway plan and the EM sensor extends distally from the EWC and senses the EM field. The US transducer extends distally from a distal end of the EWC and generates US waves and receives US waves reflected from the luminal network and the processor processes the sensed EM field to synchronize a location of the EM sensor in the 3D model, to process the reflected US waves to generate images, or to integrate the generated images with the 3D model.

    Abstract: A surgical probe includes a connection hub, an antenna assembly, and an outer jacket. The antenna assembly is coupled to the connection hub, extends distally from the connection hub, and includes a radiating portion coupled thereto at the distal end thereof. The radiating portion is configured to deliver energy to tissue to treat tissue. The outer jacket is coupled to the connection hub, extends distally therefrom, and is disposed about the radiating portion. The outer jacket includes a distal end member configured to be spaced-apart from the radiating portion a target axial distance. One or more of the couplings between the antenna assembly and the connection hub, the radiating portion and the antenna assembly, and the outer jacket and the connection hub defines a flexible configuration permitting axial movement therebetween to maintain the target axial distance between the radiating portion and the distal end member.
