    Abstract: According to one embodiment of the present disclosure a microwave ablation system is disclosed. The microwave ablation system includes an energy source adapted to generate microwave energy and a plurality of energy delivery devices having a first energy delivery device configured to be inserted into tissue and to generate a non-directional ablation volume and a second energy delivery device configured to be positioned relative to the tissue and to generate a directional ablation volume. The system also includes a power dividing device having an input adapted to connect to the energy source and a plurality of outputs configured to be coupled to the plurality of energy delivery devices. The power dividing device is configured to selectively divide energy provided from the energy source between the plurality of energy delivery devices.

    Abstract: An ablation device includes an antenna assembly having a radiating portion configured to deliver energy from a power source to tissue of a patient. The radiating portion has an outer conductor and an inner conductor extending therethrough. The inner conductor is disposed within the outer conductor and defines a longitudinal axis. One of the inner conductor and the outer conductor is movable relative to the other to cause at least a portion of the outer conductor to expand radially relative to the longitudinal axis.

    Abstract: Various high-strength microwave antenna assemblies are described herein. The microwave antenna has a radiating portion connected by a feedline to a power generating source, e.g., a generator. The antenna is a dipole antenna with the distal end of the radiating portion being tapered and terminating at a tip to allow for direct insertion into tissue. Antenna rigidity comes from placing distal and proximal radiating portions in a pre-stressed state, assembling them via threaded or overlapping joints, or fixedly attaching an inner conductor to the distal portion. The inner conductor is affixed to the distal portion by, e.g., welding, brazing, soldering, or by adhesives. A junction member made from a hard dielectric material, e.g., ceramic, can be placed between the two portions and can have uniform or non-uniform shapes to accommodate varying antenna designs. Electrical chokes may also be used to contain returning currents to the distal end of the antenna.

    Abstract: A microwave ablation system includes a power source. A microwave antenna is adapted to connect to the power source via a coaxial cable that includes inner and outer conductors having a compressible dielectric operably disposed therebetween. The inner conductor in operative communication with a radiating section associated with the microwave antenna. The outer conductor includes a distal end transitionable with respect to each of the inner conductor, compressible dielectric and radiating section from an initial condition wherein the distal end has a first diameter to a subsequent condition wherein the distal end has second diameter. Transition of the distal end from the initial condition to the subsequent condition enhances the delivery of microwave energy from the power source to the inner conductor and radiating section such that a desired effect to tissue is achieved.
