    Abstract: Methods, devices and systems are described for decreasing the activity of the sympathetic nervous innervation to and from the lungs and the vessels supplying the lungs to treat pulmonary medical conditions such as asthma. In one embodiment, the method may involve advancing an intravascular instrument to a target location in a blood vessel within the intercostal vasculature to ablate either or both the sympathetic afferent and efferent nerves lying within the paravertebral gutter including the visceral fibers that travel to the cardiothoracic cavity and abdominopelvic viscera and the Tl to T4/5 sympathetic chain. In another embodiment, an intravascular instrument may be advanced to the bronchial vessels to ablate either or both the sympathetic afferent and efferent nerves in and around the posterior pulmonary plexus. In one embodiment the ablative agent is a neurolytic agent delivered in a gel. This approach may be utilized to treat other cardiac and pulmonary diseases.

    Abstract: Apparatus and methods suitable for causing tissue ablation at a specified therapeutic site in the body of a patient. The apparatus comprises an ablation device having a distal end and a proximal end and a central lumen extending along its length, the distal end comprising at least one energy delivery element suitable for causing tissue ablation. A penetrating member having a distal end and a proximal end, the distal end comprising a sharp tip suitable for piercing tissue and creating a channel for the device in the tissue, is coaxially positioned within the central lumen of the ablation device and is capable of being advanced distally out of the central lumen of the device and retracted back to within the central lumen of the device. The apparatus may further comprise an endoscope for delivery of the device to the site of treatment.

    Abstract: A microwave applicator for insertion into living body tissue to provide microwave ablation treatments includes a microwave transmission line extending between an attachment end of the applicator and an antenna toward an insertion end of the applicator with an outer conductive sleeve forming an enclosed fluid space around the transmission line. Circulation of cooling fluid is guided in the fluid space by a guide sleeve. A sensor senses the approximate temperature of the cooling fluid. A portion of the fluid can be injected into tissue surrounding the applicator to hydrate tissue not to be treated. Microwave power may be provided to one or more of the applicators by a system which includes a multiplexing and power splitting circuit providing power outputs tuned for either one or a plurality of applicators and detects the number of applicators and correct connection. The system may provide microwave energy of both 915 MHz and 2450 MHz.

    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.
