An electrosurgical device () is provided that is operable to deliver microwave energy within a controlled angular expanse to cause targeted tissue ablation. The device () comprises a blocking or reflecting material such as cylindrical members () that are laterally spaced from the antenna () that is operable to emit the microwave energy. The reflecting material creates regions in and/or surrounding the device into which sensors (), such as thermocouple wires, may be placed to monitor a condition associated with the device or the patient's body.

Minimally invasive microwave ablation device

An electrosurgical device () operable to deliver microwave energy to cause targeted tissue ablation is provided. The electrosurgical device () comprises an antenna (), a reflector (), and a dielectric material () disposed therebetween. The selection of the dielectric material () and the relative positioning of the antenna () and the reflector () provide impedance matching between the antenna () and a transmission line () so as to minimize heating along the length of the device () during use.

High-efficiency, directional microwave ablation antenna

A novel microwave ablation applicator includes a flexible tubular shaft and a partially encapsulated antenna. The applicator is adapted to be used with an endoscope in order to access remote targets deep within an organ of a patient. Microwave power is emitted from the antenna in a desired radiation pattern by circulating an attenuating liquid through the shaft and across a portion of the antenna. Microwave ablation systems and methods are described.

Bronchoscopic-based microwave ablation system and method

A novel monitoring method evaluates tissue ablation progress. An antenna in a distal portion of an ablation applicator sends and receives electrical information from the target tissue during ablation. The information is used to determine ablation progress. A related ablation monitoring system includes a power monitor and processor operable to evaluate ablation progress based on reflected electrical properties during the ablation. The invention has particular benefits when used in endoscopic-based microwave ablation.
