Re-hydration antenna for ablation

摘要

A microwave ablation device having a handle body (112); a microwave antenna (104) operatively coupled to the handle body (112); a cable connector (17) configured to connect the microwave antenna (104) in electrical communication to an energy source (37) via a feedline (14); an outer jacket (108) surrounding the microwave antenna (104) to 5 define a fluid volume, the outer jacket (108) defining a plurality of fluid distribution ports (114) in fluid communication with the fluid volume and configured to permit the flow of fluid into surrounding tissue of a patient; at least one inflow tubing (19) in fluid communication with the fluid volume defined by the microwave antenna (104) and the outer jacket (108); and a helical-shaped inlet tube (126) encircling at least a portion of the 10 microwave antenna (104), the helical-shaped inlet tube (126) in fluid communication with the at least one inflow tubing (19) and the fluid volume. 10167676 1 IRN: 901631D2
