The present disclosure relates to systems, devices and methods for providing visual guidance for navigating inside a patient's chest. An exemplary method includes presenting a three-dimensional (3D) model of a luminal network, generating, by an electromagnetic (EM) field generator, an EM field about the patient's chest, detecting a location of an EM sensor within the EM field, determining a position of a tool within the patient's chest based on the detected location of the EM sensor, displaying an indication of the position of the tool on the 3D model, receiving cone beam computed tomography (CBCT) image data of the patient's chest, detecting the location of the tool within the patient's chest based on the CBCT image data, and updating the indication of the position of the tool on the 3D model based on the detected location.

A surgical energy system includes a first and second surgical instruments and a generator including a universal interface. The first surgical instrument includes a first instrument connector having one or more instrument couplers disposed in a first instrument coupler configuration. The second surgical instrument includes a second instrument connector having one or more instrument couplers disposed in a second instrument coupler configuration. The first and second instrument coupler configurations are different. The generator includes a universal interface including generator couplers arranged to provide generator coupler configurations at the universal interface. Each generator coupler configuration accommodates one of the first and second instrument coupler configurations in order to electronically couple the generator to a respective one of the first and second surgical instruments.

An electrosurgical forceps instrument in which an energy conveying structure for efficiently transferring electromagnetic energy (e.g. microwave energy and/or radiofrequency energy) from a coaxial cable to electrodes on the forceps jaws is incorporated into a compact jaw opening structure. The jaw opening structure may be dimensioned to be suitable for insertion down the instrument channel of a endoscope or other scoping device. Alternatively, the device may be configured as a laparoscopic device or be used in open procedures. The instrument may be used as a tool to perform new minimally invasive surgical techniques such as Natural Orifice Transluminal Endosurgery (NOTES) or the like.

The invention generally relates to systems and methods for therapeutically modulating nerves in or associated with a nasal region of a patient for the treatment of a rhinosinusitis condition.

A microwave field-detecting needle assembly includes a needle assembly. The needle assembly includes a distal portion, a proximal portion, and a junction member disposed between the distal portion and the proximal portion. The junction member includes a recess defined therein. The needle assembly also includes a rectifier element disposed in the recess. The rectifier element includes a first terminal electrically coupled to the distal portion and a second terminal electrically coupled to the proximal portion.

A microwave ablation system incorporates a microwave thermometer that couples to a microwave transmission network connecting a microwave generator to a microwave applicator to measure noise temperature. The noise temperature is processed to separate out components of the noise temperature including the noise temperature of the tissue being treated and the noise temperature of the microwave transmission network. The noise temperature may be measured by a radiometer while the microwave generator is generating the microwave signal or during a period when the microwave signal is turned off. The microwave ablation system may be configured as a modular system having one or more thermometry network modules that are connectable between a microwave applicator and a microwave generator. Alternatively, the modular system includes a microwave generator, a microwave applicator, and a microwave cable that incorporate a microwave thermometry network module.

A bed leveling system for a surgical table, which incorporates a platform adapted for a patient to lie down upon, includes an energy emitting device and a first spacer. The energy emitting device is configured and dimensioned to be positioned on a platform of a surgical table. The first spacer is configured to be positioned on a platform of a surgical table to support a portion of a patient's body. The first spacer has a thickness such that a top surface of the first spacer is substantially flush with a top surface of the energy emitting device when disposed adjacent the energy emitting device on a platform of a surgical table.

A microwave ablation antenna assembly (20) incorporates an improved choke assembly (40) which provides the antenna assembly (20) with both a largely spherical ablation pattern and an improved impedance matching characteristic.

Provided in accordance with aspects of the present disclosure is a microwave ablation system including an introducer having a lumen therethrough, a stylus configured for slidable engagement within the lumen of the introducer, and a microwave ablation antenna configured to deliver energy to a target during an ablation procedure, wherein the microwave ablation antenna is configured for slidable engagement within the lumen of the introducer.

An electrosurgical system includes an electrosurgical power generating source, an energy applicator operably associated with the electrosurgical power generating source, a processor unit, and a data acquisition module configured to receive a reflected signal. The processor unit is disposed in operative communication with the data acquisition module and adapted to determine a tissue desiccation rate around at least a portion of the energy applicator based on one or more signals received from the data acquisition module.
