Abstract: 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.

Abstract: The present disclosure describes an instrument for measuring the dielectric properties of biological tissue. The instrument includes a top electrode assembly and a bottom electrode assembly, the top electrode assembly including a top electrode and at least one shaft adjustably positionable to move the top electrode relative to the bottom electrode assembly, the bottom electrode assembly including a bottom test plate and a bottom electrode. The instrument also includes a testing cylinder coupled to the shaft and having an inner cavity defined therein that houses the top electrode and which is designed to enclose the bottom electrode therein. The testing cylinder is configured to reduce at least one of electric current, magnetic current, stray radiative RF fields and external capacitive leakage currents during activation of the top and bottom electrodes.
