Claim 0:
1. A system comprising:
one or more devices configured for delivery of energy to a tissue; and
one or more of a power generator, a temperature monitoring device, a power distributor, a coolant source, and a processor;
wherein said one or more devices configured for delivery of energy to the tissue is
a device comprising a feedline portion comprising an inner and outer conductor separated by dielectric material, and an antenna portion distal to said feedline portion,
wherein said feedline portion has an outer diameter that is equal to or less than a 16-gauge needle and wherein said feedline portion comprises one or more coolant pathways between said inner conductor and said outer conductor,
wherein the feedline portion has a proximal end and a distal end,
wherein the antenna portion has a proximal end and a distal end,
wherein said one or more coolant pathways are created by removing a portion of said dielectric material, wherein said one or more coolant pathways are non-linear along the feedline portion, wherein the one or more coolant pathways are non-linear with respect to a feedline portion axis from the proximal end of the feedline portion to the distal end of the feedline portion,
wherein the inner conductor extends from the proximal end of the feedline portion to the distal end of the antenna portion,
wherein the outer conductor and dielectric material extend from the proximal end of the feedline portion to the distal end of the feedline portion,
wherein said outer diameter is equal to or less than a 20-gauge needle,
wherein said one or more coolant pathways terminate within said feedline portion;
wherein said feedline portion comprises a triaxial configuration having said inner conductor, said outer conductor, and a middle conductor disposed between the inner and outer conductors.
