Abstract: An ablation instrument having an ergonomic handle that includes an actuator adapted to selectively extend and retract a blade that is pivotably mounted within an aperture assembly coupled to the housing by a shaft. The shaft extends distally from the handle and includes a coaxial feedline, a wire conduit disposed along a longitudinal axis of the shaft, and a pull wire disposed within the wire conduit and having a proximal and a distal end, wherein a proximal end of the pull wire is operably coupled to the actuator. The aperture assembly is coupled to a distal end of the shaft and includes a reflector having a closed upper portion, and an open lower portion from which the blade may be extended for use. Also disclosed is an ablation system that includes the above-described ablation instrument, a source of ablation energy, and optionally, a source of coolant for cooling the shaft and aperture assembly.

Abstract: A guide block introduces electrodes into target tissue and includes an elongated, generally rectilinear bar having a plurality of slots defined therethrough. Each of the slots is configured to selectively receive and retain a corresponding electrode therein. The rectilinear bar is malleable and selectively bendable from a substantially linear configuration to a substantially curved configuration to facilitate positioning the guide block relative to target tissue.

Abstract: Ablation systems and methods detect and address distortion caused by a variety of factors. A method includes measuring a temperature curve at target tissue; applying ablation energy to the target tissue; determining a peak temperature on the temperature curve; if the peak temperature is greater than the predetermined peak temperature, determining a time at which the temperature curve crosses to a lower temperature; and if the determined time is greater than a predetermined time, generating a message indicating that the target tissue was successfully ablated. Another method includes determining a distance between a remote temperature probe and an ablation probe, applying ablation energy to target tissue, measuring temperature at the remote temperature probe, estimating ablation size based on the determined distance and the temperature measured by the remote temperature probe, and determining whether the target tissue is successfully ablated based on the estimated ablation size.

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.
