The present disclosure relates to systems and devices for positioning and placing multiple electrodes in a target surgical site. A guide block is disclosed which introduces electrodes into target tissue and includes an elongated, generally rectilinear bar having a plurality of slots defined therethrough. Each of the slots is configured to selectively receive and retain a corresponding electrode therein. The rectilinear bar is malleable and selectively bendable from a substantially linear configuration to a substantially curved configuration to facilitate positioning the guide block relative to target tissue.

A system for monitoring and/or controlling tissue modification during an electrosurgical procedure is provided. The system includes an electrosurgical apparatus adapted to connect to an electrosurgical generator. The electrosurgical apparatus configured to transmit energy to tissue. The system also includes a control system having one or more electromagnetic wave sources configured to generate the interrogator wave of one or more frequencies adjacent tissue. One or more sensors are configured to transmit and sense a reflected portion of the interrogator wave of at least one frequency to determine dielectric boundary data. A processor operatively coupled to the control system and to the electrosurgical generator configured to control the delivery of electrosurgical energy from the electrosurgical generator to tissue based on dielectric boundary data provided by the one or more sensors.

A system for providing feedback during an electrosurgical procedure on a target tissue is provided. The system includes an electrosurgical energy source; an electrode probe assembly connected to the electrosurgical energy source, wherein the electrode probe assembly includes at least one electrode assembly having a needle configured to deliver electrosurgical energy to the target tissue; at least one thermal feedback assembly connected to the electrosurgical energy source, wherein each thermal feedback assembly includes at least one temperature sensor assembly; and a hub configured to selectively support the electrode probe assembly and each thermal feedback assembly such that the needle of the electrode probe assembly and each temperature sensor assembly of each thermal feedback assembly are proximate one another when disposed proximate the target tissue.

A method for determining a volume of ablated tissue includes the steps of supplying energy to tissue, indicating an axis within the tissue, and simulating slicing of the tissue substantially perpendicular to the axis to obtain a plurality of simulated slices. Each of the plurality of simulated slices has a thickness, a cross-sectional perimeter, and a trajectory point defined by the axis within the tissue. The method further includes the steps of determining a volume of each of the plurality of simulated slices based on the trajectory point, the cross-sectional perimeter, and the thickness of each simulated slice, and summing the volumes from each of the plurality of simulated slices to obtain the volume of the ablated tissue.

A system for use with a microwave antenna includes a microwave antenna configured to deliver microwave energy from a power source to tissue and a sensor module in operative communication with the power source and configured to detect a reflectance parameter. The system further includes a jacket adapted to at least partially surround the microwave antenna to define a fluid channel between the jacket and the microwave antenna. A plurality of fluid distribution ports are defined through the jacket and are in fluid communication with the fluid channel to permit the flow of fluid through the jacket. The system further includes a fluid pumping system operably coupled to the power source and configured to selectively provide cooling fluid to the fluid channel for distribution through the fluid distribution ports based on the reflectance parameter.
