    摘要: A method of performing an ablation procedure includes the initial step of supplying a fluid to a cooling chamber defined within an antenna assembly. The method also includes the steps of decreasing the temperature of the fluid to form a solid material and inserting the antenna assembly into tissue. The method also includes the step of supplying energy to the antenna assembly to treat tissue. Residual heat from the antenna assembly transitions the solid material back to the fluid. The method also includes the step of circulating the fluid within the antenna assembly to dissipate heat emanating from the antenna assembly.

    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.

    摘要: A system for determining field of ablation is disclosed. The system includes a power source configured to generate electromagnetic energy and an energy applicator coupled to the power source. The energy applicator is configured to be inserted into tissue and to provide electromagnetic energy to a target volume. The system also includes an imaging apparatus configured to generate a uniform magnetic field and at least one variable magnetic field around the tissue. The imaging apparatus obtains an image of a field of ablation within the target volume in response to a trace RF pulse supplied by the power source through the energy applicator to the target volume simultaneously with an excitation RF pulse generated by the imaging apparatus and the at least one variable magnetic field.
