摘要：
Devices and methods are disclosed for treating tissue with microwave energy. Such devices and methods are able to treat cavities or surface tissue by creating one or more area or volumetric lesions. Also disclosed are flexible, low-profile devices that can be inserted non-invasively or minimally invasively near or into the target tissue as well as microwave antennas designed to generate ablation profiles that can ablate a large area or a large volume of target tissue in a single ablation. The devices include antennas wherein the field profile generated by an antenna is tailored and optimized for a particular clinical application. The antennas use unique properties of microwaves such as interaction of a microwave field with a metallic object and the use of additional shaping elements to shape the microwave field.
