Abstract: A system for light based interrogation of a lung includes a memory, an electromagnetic (EM) board, an extended working channel (EWC), an EM sensor, a light source, a light receptor and a processor. The memory stores a 3D model and a pathway plan of a luminal network and the EM board generates an EM field. The EWC navigates a luminal network of a patient toward a target in accordance with the pathway plan and the EM sensor extends distally from a distal end of the EWC and is configured to sense the EM field. The light source is located at or around the EWC and emits light, and the light receptor is located at or around the EWC and is configured to sense reflected light from airway of the luminal network. The processor converts the reflected light into light based data and identifies a type or density of tissue.

Abstract: A method of directing energy to tissue includes the initial step of positioning an energy applicator for delivery of energy to target tissue. The energy applicator is provided with a surface-contact detection device including one or more optical transmitters and one or more optical receivers. The energy applicator is operably associated with an electrosurgical power generating source. The method also includes the steps of determining whether a radiating portion of the energy applicator is disposed in contact with the target tissue based on a determination of whether optical signals generated by the one or more optical transmitters result in reflected optical signals received at the one or more optical receivers, and if it is determined that the radiating portion of the energy applicator is disposed in contact with tissue, transmitting energy from the electrosurgical power generating source through the radiating portion to the target tissue.

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. A radiation detection device is operably disposed on the microwave antenna. The radiation detection device is configured to generate a voltage corresponding to a radius of the ablation zone, wherein the radiation detection device is in operative communication with at least one module associated with the power source. The at least one module triggers a signal when a predetermined threshold voltage 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: Disclosed is a system and method for enabling user preview and control of the size and shape of an electromagnetic energy field used in a surgical procedure. The disclosed system includes a selectively activatable source of microwave surgical energy in the range of about 900 mHz to about 5 gHz in operable communication with a graphical user interface and a database. The database is populated with data corresponding to the various surgical probes, such as microwave ablation antenna probes, that may include a probe identifier, the probe diameter, operational frequency of the probe, ablation length of the probe, ablation diameter of the probe, a temporal coefficient, a shape metric, and the like. The probe data is graphically presented on the graphical user interface where the surgeon may interactively view and select an appropriate surgical probe. Three-dimensional views of the probe(s) may be presented allowing the surgeon to interactively rotate the displayed image.
