摘要: 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.

摘要: 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.

摘要: A method of manufacturing a microwave antenna assembly includes the step of providing a proximal portion having an inner conductor and an outer conductor. Each of the inner and outer conductors extend through the proximal portion and the inner conductor is disposed within the outer conductor. The method also includes the step of placing a junction member adjacent to a distal end of the proximal portion such that the inner conductor extends through a channel defined in the junction member. The method also includes the step of placing a proximal end of a distal portion adjacent to a distal end of the junction member such that the inner conductor extends within a channel defined within the distal portion. The method also includes the step of affixing the inner conductor to the distal portion such that the proximal portion and the distal portion apply a compressive force on the junction member.
