摘要:
A microwave applicator for insertion into living body tissue for use in microwave coagulation and ablation treatments includes a microwave transmission line extending between an attachment end of the applicator and an antenna toward an insertion end of the applicator with an outer conductive sleeve forming an enclosed fluid space around the transmission line. A fluid circulation system circulates fluid in the fluid space. A portion of or all of the circulating fluid can be injected into tissue that surrounds the applicator body from approximately the proximal end of a desired heating zone produced by microwave energy radiated from the antenna along the applicator body toward the proximal end of the applicator to hydrate and wet the tissue outside the proximal end of the desired heating zone to reduce the drying of this tissue and limit extension of the heating and ablation zone proximally along the applicator body.
