MICROWAVE FIELD-DETECTING NEEDLE ASSEMBLIES, METHODS OF MANUFACTURING SAME, METHODS OF ADJUSTING AN ABLATION FIELD RADIATING INTO TISSUE USING SAME, AND SYSTEMS INCLUDING SAME

摘要

A method of adjusting an ablation field radiating into tissue includes the initial steps of providing an energy applicator and providing one or more microwave field-detecting needle assemblies. Each microwave field-detecting needle assembly includes one or more rectifier elements capable of detecting microwave field intensity via rectification. The method includes the steps of positioning the energy applicator and the one or more microwave field-detecting needle assemblies in tissue, transmitting energy from an energy source through the energy applicator to generate an ablation field radiating about at least a portion of the energy applicator into tissue, and adjusting the ablation field radiating about at least the portion of the energy applicator into tissue based on at least one electrical signal transmitted by the one or more microwave field-detecting needle assemblies.

1. A method of adjusting an ablation field radiating into tissue, the method comprising:
positioning an energy applicator into tissue; positioning at least one microwave field-detecting needle assembly in tissue independently from the energy applicator, the at least one microwave field-detecting needle assembly including at least one rectifier element capable of detecting microwave field intensity via rectification; transmitting energy from an energy source through the energy applicator to generate an ablation field radiating about at least a portion of the energy applicator into tissue; and adjusting the ablation field radiating about the at least a portion of the energy applicator into tissue based on at least one electrical signal transmitted by the at least one microwave field-detecting needle assembly.
