    摘要: A method of performing an ablation procedure includes the steps of inserting an antenna assembly into tissue and supplying energy thereto for application to tissue. The method also includes the step of causing contact between a first material and at least one other material disposed within the antenna assembly to thermally regulate the antenna assembly. According to another embodiment, an ablation system includes an energy delivery assembly. A first chamber is defined within the energy delivery assembly and is configured to hold a first chemical. Another chamber is defined within the energy delivery assembly and is configured to hold at least one other chemical. The first chamber and the other chamber are configured to selectively and fluidly communicate with each other to cause contact between the first chemical and the at least one other chemical to cause an endothermic reaction and/or an exothermic reaction.

    摘要: A device for directing energy to a target volume of tissue includes an antenna assembly and an elongated body member. The elongated body member includes a proximal end portion and a distal end portion, wherein the proximal and distal end portions define a longitudinal axis. The elongated body member has a chamber defined therein that extends along the longitudinal axis, and a body wall surrounding the chamber. An antenna assembly is disposed in the chamber. The elongated body member also includes an opening in the body wall to allow energy radiated from the antenna assembly to transfer into the target volume of tissue.

    摘要: 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.

    摘要: A surgical ablation system employing an ablation probe having a deployable ground plane is disclosed. The disclosed system includes a source of ablation energy and a source of electrosurgical energy, and a switching assembly configured to select between ablation and electrosurgical modes. The probe includes a cannula having a shaft slidably disposed therein. The shaft includes a deployable ground plane electrode assembly and a needle electrode disposed at distal end of the shaft. As the shaft is extended distally from the cannula, the ground plane electrode unfolds, and the needle electrode is exposed. Electrosurgical energy is applied to tissue via the needle electrode to facilitate the insertion thereof into tissue. Ablation energy is applied to tissue via the needle electrode to achieve the desired surgical outcome. The shaft, ground plane electrode and needle electrode are retracted into the cannula, and withdrawn from the surgical site.
