摘要： A method of fabricating a microwave antenna assembly is disclosed. The fabrication method includes providing a proximal portion having an inner conductor and an outer conductor, the inner conductor extending at least partially therein. The method further includes providing a distal portion disposed distally of the proximal portion, with the inner conductor extending at least partially therein. A high strength material may be injected from an inflow slot to an outflow slot of the distal portion such that the material is disposed in-between the inner conductor and a ceramic layer. The material bonds the distal portion and the ceramic layer to the proximal portion while providing mechanical strength to the distal portion.

摘要： An electromagnetic surgical ablation probe having a tunable helical antenna element is disclosed. The probe includes a coaxial feedline having an inner conductor coaxially disposed within a dielectric, and an outer conductor coaxially disposed around the dielectric. The inner conductor and dielectric extend distally beyond a distal end of the outer conductor. A helical antenna element is operably coupled to a distal end of the inner conductor. During use, the antenna may be tuned by changing at least one dimension of the helical antenna element. Embodiments are presented wherein a dimensions of the helical antenna element is changed by state change of a shape memory alloy, by a change in temperature, by activation of a piston by fluidic pressure, by linear motion of a conical tip, and by a manual screw-type adjustment.

摘要： A system for generating microwave energy includes a microwave generator that generates first and second microwave signals, a transmission line and a dual antenna microwave device. The transmission line transmits the first and second microwave signals to the microwave device. The microwave device includes a first antenna proximal a second antenna and a dual-sided choke positioned therebetween. The first antenna receives the first microwave signal from the transmission line between a first conductor and a second conductor and the second antenna receives the second microwave signal between the second conductor and a third conductor. The dual-sided choke includes a first and a second antenna choke circuit. The first antenna choke circuit limits the propagation of electromagnetic fields generated by the first antenna toward the second antenna and the second antenna choke circuit limits the propagation of electromagnetic fields generated by the second antenna toward the first antenna.
