CABLE WITH MICROWAVE EMITTER

摘要

A microware emitter cable system is disclosed. The system can have a coaxial cable that can have an outer conductor, dielectric insulator radially inside the outer conductor, and an inner conductor radially inside of the dielectric. The system can have multiple passageways radially inside of the outer conductor. The passageways can extend to the distal terminal end of the cable.

1. A method for delivering microwave energy to a target biological tissue comprising:
positioning a guidewire adjacent to the target biological tissue; delivering a coaxial cable comprising a microwave emitter over the guidewire, wherein the cable has a longitudinal axis, and wherein the cable comprises an inner conductor, an outer conductor insulated from and radially outside of the inner conductor, and a lumen radially inside of the outer conductor, and wherein the lumen extends through the emitter, and wherein the guidewire slides through the lumen; removing the guidewire from the lumen; and delivering a fluid to the lumen, wherein the fluid flows in the first lumen longitudinally distal to the emitter.
