Abstract: A system for monitoring ablation size is provided and includes a power source including a microprocessor for executing at least one control algorithm. A microwave antenna is configured to deliver microwave energy from the power source to tissue to form an ablation zone. An ablation zone control module is in operative communication with a memory associated with the power source. The memory includes one or more data look-up tables including data pertaining to a control curve varying over time and being representative of one or more electrical parameters associated with the microwave antenna. Points along the control curve correspond to a value of the electrical parameters and the ablation zone control module triggers a signal when a predetermined threshold value of the electrical parameter(s) is measured corresponding to the radius of the ablation zone.

Abstract: 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.

Abstract: A surgical system includes a power supply, a power stage coupled to the power supply for converting electric energy to a power signal, an audio output device, a sensor, and a controller coupled to the power supply, the power stage, and the audio output device. The controller is operably coupled to the sensor. The power stage is configured to transmit the power signal to a surgical instrument such as an electrosurgical instrument or a microwave instrument. The sensor may be disposed on the surgical instrument. The controller causes the audio output device to output sensory feedback during operation of the surgical generator based on sensor signals received from the sensor during a surgical procedure.
