A method for displaying real-time ablation growth projections is provided. The method includes applying, by a processor, an ablation model to image data of a patient. The ablation model is based on a position of an ablation probe, and the ablation probe is coupled to the processor. The method also includes displaying, on a display coupled to the processor, a projected ablation zone on the image data. The projected ablation zone is based on ablation parameters and the position of the ablation probe. The projected ablation zone includes a margin showing a confidence level. The method further includes ablating by the ablation probe. The ablating is based on an evaluation of the projected ablation zone with respect to a target. A system for performing a microwave ablation procedure is provided. A non-transitory computer-readable storage medium storing instructions is provided.

Ablation system with display for real-time ablation growth projection, and method therefor

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.

System for tracking and imaging a treatment probe

The visualization method includes displaying three-dimensional image data of at least one anatomical feature of a patient, receiving user input of the target for placing an ablation needle in the at least one anatomical feature of the patient, determining the position and orientation of the ablation needle based on the user input, displaying an image of a virtual ablation needle in the three-dimensional image data of the at least one anatomical feature of the patient according to the determined position and orientation, receiving user input of parameters of operating the ablation needle, and displaying a three-dimensional representation of the result of operating the ablation needle according to the input parameters.

Systems and methods for ablation visualization

A microwave ablation device including a cable assembly configured to connect a microwave ablation device to an energy source and a feedline in electrical communication with the cable assembly. The microwave ablation device further includes a balun on an outer conductor of the feedline, and a temperature sensor on the balun sensing the temperature of the balun.

Microwave energy-delivery device and system

A system for ultrasound interrogation of a lung including 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 and pathway plan for navigating a luminal network. The EM board generates an EM field. The EWC is configured to navigate the luminal network toward a target following the pathway plan. The EM sensor extends distally from a distal end of the EWC and is configured to sense the EM field. The US transducer extends distally from a distal end of the EWC, generates US waves, and receives US waves reflected from the luminal network. 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.

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.

Microwave ablation system

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.

Systems and methods for thermal ablation distortion detection

A method for forming a resonating structure within a body lumen, the method including advancing a flexible microwave catheter into a body lumen of a patient, the flexible microwave catheter including a radiating portion at the distal end of the flexible microwave catheter, the radiating portion configured to receive microwave energy, and at least one centering device proximate the radiating portion configured to deploy radially outward from the flexible microwave catheter; positioning the radiating portion near tissue of interest; deploying the at least one centering device radially outward from the flexible microwave catheter within the body lumen such that a longitudinal axis of the radiating portion is substantially parallel with and at a fixed distance from a longitudinal axis of the body lumen near the targeted tissue; and delivering microwave energy to the radiating portion such that a circumferentially balanced resonating structure is formed with the body lumen.
