摘要： The present invention discloses access devices and methods to create an access channel for introduction of one or more working devices into an anatomical region. The access channel is created using a visualization modality that is later removed before inserting one or more working devices through the access channel. This allows the methods and devices of the present invention to be used even in small sized natural or surgically created insertion tracts leading to the anatomical region. The access channel can be made of a device such as a sheath, a guidewire, and an elongate device comprising a lumen. Examples of visualization modalities are endoscopes and body insertable ultrasound imaging devices. The working devices can be used to perform a variety of diagnostic, therapeutic, or preventive procedures. Endometrial ablation devices and procedures have been used as an example to describe various aspects of the present invention.

摘要： The invention comprises novel microwave antennas wherein the microwave field profile generated by an antenna is tailored and optimized for a particular clinical application. The antennas disclosed herein incorporate one or more additional elements called shaping elements that use unique properties of microwaves such as interaction of a microwave field with one or more conductive or non-conductive elements to shape or redistribute the microwave field. Such shaping elements may be used to reduce the undesired backward coupling of the emitted microwave field to the transmission line. Such shaping elements may be used to increase the power efficiency of the antenna. The invention also discloses devices and methods for treating tissue with microwave energy emitted from the antennas for use in applications such as destroying a soft tissue by microwave ablation.

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.
