摘要： A microwave antenna assembly is disclosed. The antenna assembly includes an elongated member defining a longitudinal axis and having proximal and distal ends. The antenna assembly also includes an outer conductor and an inner conductor each disposed within the elongated member and extending along the longitudinal axis. A portion of the inner conductor is deployable relative to the outer conductor such that the antenna assembly may transition from a first configuration to a second configuration. The antenna assembly also includes an expandable sheath at least partially disposed about a distal portion of the inner conductor and defining at one or more lumens configured to couple to a supply of dielectric material used to regulate the expansion of the expandable sheath.

摘要： A method of deploying an antenna of an ablation device includes the step of placing an introducing member relative to tissue. The introducing member is disposed on a distal end of a handle member. The method also includes the steps of advancing an antenna distally through the handle member and at least partially through the introducer and rotating the handle member about the longitudinal axis thereof relative to the antenna. The method also includes the step of moving the handle member proximally along the longitudinal axis thereof to retract the introducer proximally relative to the antenna such that the antenna is at least partially deployed relative to the introducer to treat tissue.

摘要： A microwave ablation system is provided. The microwave ablation system includes a power source. A microwave antenna is adapted to connect to the power source via a coaxial cable feed including an inner conductor defining a portion of a radiating section of the microwave antenna, an outer conductor and dielectric shielding. The inner conductor loops back around and toward the outer conductor of the coaxial cable feed such that a distal end of the inner conductor is operably disposed adjacent the dielectric shielding. The inner conductor includes one or more reactive components disposed thereon forming a reactively-loaded loop configuration configured to maximize delivery of microwave energy from the power source to tissue such that a desired effect to tissue is achieved.
