摘要： A microwave ablation system includes a first cannula, a trocar insertable through the first cannula and configured to facilitate insertion of the first cannula into a target tissue, and a microwave antenna assembly configured to interlock with the first cannula, the microwave antenna assembly including a coaxial feedline having a radiating section formed thereon, the microwave antenna configured to be inserted into the first cannula. The microwave ablation system further includes an actuator operatively connected to one of the first cannula or microwave antenna assembly. Operation of the actuator between a first position and a second position exposes the radiating section of the microwave antenna assembly from a distal portion of the first cannula.

摘要： A system including a catheter navigable to a location within a patient, a lumen extending through the catheter and ending at the distal end in an orifice, a fluid controller in fluid communication with the lumen of the catheter and capable of supplying a fluid to or removing a fluid from an area proximate the desired location. The control of the fluid in the area proximate the desired location affecting a dielectric constant of the area proximate the desired location. The system includes a microwave energy source, and a microwave ablation probe connected to the microwave energy source, the microwave ablation probe being navigable to a desired location within the patient. Application of energy from the microwave energy source to the microwave ablation probe in an area proximate the desired location having the affected dielectric constant results in a substantially spherical tissue effect in the area proximate the desired location.

摘要： A surgical instrument for ablating tissue includes a handle portion and a shaft assembly extending distally from the handle portion. The shaft assembly includes an outer shaft, a coaxial cable extending through the outer shaft, and an electrode coupled to a distal portion of the outer shaft. The coaxial cable has a distal portion that forms a microwave antenna configured to transmit microwave energy radially outward and through the outer shaft. The electrode is configured to transmit radiofrequency energy. An actuation of the handle portion activates the transmission of the microwave energy from the microwave antenna and/or the transmission of the radiofrequency energy from the at least one electrode.

摘要： A microwave antenna including a feedline, a radiating section, an inflow hypotube, a puck, a transition collar and a sleeve. The feedline includes a coaxial cable including an inner and outer conductor, and a dielectric disposed therebetween. The radiating section includes a dipole antenna coupled to the feedline and a trocar coupled to the distal end of the dipole antenna. The inflow hypotube is disposed around the outer conductor and configured to supply fluid to the radiating portion. The puck includes at least two ribs with inflow slots defined between two adjacent ribs. The transition collar is coupled to the distal end of the inflow hypotube and the first end of the puck. The transition collar includes at least two outflow slots configured to receive fluid from a distal end of the inflow hypotube and to transition the fluid from the outflow slots to a distal end of the radiating section. The sleeve overlays the two outflow slots of the transition collar, the puck and at least the distal portion of the radiating section. The sleeve forms a fluid-tight seal with the transition collar proximal the outflow slots and defines a first gap for transitioning the fluid to exit the outflow slots of the transition collar to the distal end of the radiating section.

摘要： 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.

摘要： 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.
