Abstract: A method for identifying and treating tissue includes providing an electrosurgical treatment device including an electrode assembly. One or more electrical property values of target tissue are measured. The measured electrical property values of the target tissue are compared against electrical property values of known tissue types. A tissue type of the target tissue is identified. An energy delivery configuration of the electrosurgical treatment device is adjusted to the type of target tissue. The electrosurgical treatment device is activated to treat the target tissue.

Abstract: A microwave antenna assembly is disclosed. The antenna assembly includes an elongated member defining a longitudinal axis and having proximal and distal ends. The antenna assembly also includes an outer conductor and an inner conductor each disposed within the elongated member and extending along the longitudinal axis. A portion of the inner conductor is deployable relative to the outer conductor such that the antenna assembly may transition from a first configuration to a second configuration. The antenna assembly also includes an expandable sheath at least partially disposed about a distal portion of the inner conductor and defining at one or more lumens configured to couple to a supply of dielectric material used to regulate the expansion of the expandable sheath.

Abstract: An ablation device includes an antenna assembly having a radiating portion configured to deliver energy from a power source to tissue of a patient. The radiating portion has an outer conductor and an inner conductor extending therethrough. The inner conductor is disposed within the outer conductor and defines a longitudinal axis. One of the inner conductor and the outer conductor is movable relative to the other to cause at least a portion of the outer conductor to expand radially relative to the longitudinal axis.

Abstract: Devices and methods for cooling microwave antennas are disclosed herein. The cooling systems can be used with various types of microwave antennas. One variation generally comprises a handle portion with an elongate outer jacket extending from the handle portion. A microwave antenna is positioned within the handle and outer jacket such that cooling fluid pumped into the handle comes into contact directly along a portion of the length, or a majority of the length, or the entire length of the antenna to allow for direct convective cooling. Other variations include cooling sheaths which form defined cooling channels around a portion of the antenna. Yet another variation includes passively-cooled systems which utilize expandable balloons to urge tissue away from the surface of the microwave antenna as well as cooling sheaths which are cooled through endothermic chemical reactions. Furthermore, the microwave antennas themselves can have cooling lumens integrated directly therethrough.
