Abstract: A dipole microwave applicator emits microwave radiation into tissue to be treated. The applicator is formed from a thin coax cable having an inner conductor surrounded by an insulator, which is surrounded by an outer conductor. A portion of the inner conductor extends beyond the insulator and the outer conductor. A ferrule at the end of the outer conductor has a step and a sleeve that surrounds a portion of the extended inner conductor. A tuning washer is attached to the end of the extended inner conductor. A dielectric tip encloses the tuning washer, the extended inner conductor, and the sleeve of the ferrule. The sleeve of the ferrule and the extended inner conductor operate as the two arms of the dipole microwave antenna. The tuning washer faces the step in the ferrule, and is sized and shaped to cooperate with the step in balancing and tuning the applicator.

Abstract: A system (10) for generating microwave energy includes a microwave generator (100) that generates first and second microwave signals, a transmission line (120) and a dual antenna microwave device (110). The transmission line transmits the first and second microwave signals to the microwave device. The microwave device includes a first antenna (116a) proximal a second antenna (116b) and a dual-sided choke (128) positioned therebetween. The first antenna receives the first microwave signal from the transmission line between a first conductor and a second conductor and the second antenna receives the second microwave signal between the second conductor and a third conductor. The dual-sided choke includes a first and a second antenna choke circuit. The first antenna choke circuit limits the propagation of electromagnetic fields generated by the first antenna toward the second antenna and the second antenna choke circuit limits the propagation of electromagnetic fields generated by the second antenna toward the first antenna.

Abstract: Devices and methods for treating tissue with microwave energy used in applications such as destroying a soft tissue by microwave ablation and/or creating point, line, area or volumetric lesions. Various embodiments of flexible, low-profile devices are also disclosed where such device can be inserted non-invasively or minimally invasively near or into the target tissue such as cardiac tissue. The devices disclosed herein comprise 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 one or more conductive or non-conductive shaping elements to shape or redistribute the microwave field.
