Abstract: Various high-strength microwave antenna assemblies are described herein. The microwave antenna has a radiating portion connected by a feedline to a power generating source, e.g., a generator. The antenna is a dipole antenna with the distal end of the radiating portion being tapered and terminating at a tip to allow for direct insertion into tissue. Antenna rigidity comes from placing distal and proximal radiating portions in a pre-stressed state, assembling them via threaded or overlapping joints, or fixedly attaching an inner conductor to the distal portion. The inner conductor is affixed to the distal portion by, e.g., welding, brazing, soldering, or by adhesives. A junction member made from a hard dielectric material, e.g., ceramic, can be placed between the two portions and can have uniform or non-uniform shapes to accommodate varying antenna designs. Electrical chokes may also be used to contain returning currents to the distal end of the antenna.

Abstract: A surgical ablation system employing an ablation probe having a deployable ground plane is disclosed. The disclosed system includes a source of ablation energy and a source of electrosurgical energy, and a switching assembly configured to select between ablation and electrosurgical modes. The probe includes a cannula having a shaft slidably disposed therein. The shaft includes a deployable ground plane electrode assembly and a needle electrode disposed at distal end of the shaft. As the shaft is extended distally from the cannula, the ground plane electrode unfolds, and the needle electrode is exposed. Electrosurgical energy is applied to tissue via the needle electrode to facilitate the insertion thereof into tissue. Ablation energy is applied to tissue via the needle electrode to achieve the desired surgical outcome. The shaft, ground plane electrode and needle electrode are retracted into the cannula, and withdrawn from the surgical site.

Abstract: The present disclosure relates to devices and methods for the treatment of tissue with microwave energy. The devices and methods disclosed herein utilize an antenna assembly which includes an elongate member, an outer conductor, an inner conductor, at least a portion of which is deployable, and a cooling system. The cooling system disclosed herein may significantly curtail any theoretical, or potential negative effects upon the target tissue experienced during the transmission of microwave energy to the antenna assembly due to ohmic heating.

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.
