    摘要： A device for cooling a cable assembly for use in an electrosurgical system comprises a housing (450) defining a fluid inlet chamber (462), a fluid outlet chamber (463), and an aperture for receiving a cable assembly therethrough. A tubular sleeve member (489) extends from a distal portion of the housing. The device further has a flexible fluid-cooled shaft (410) including: an inlet sleeve (431); an outlet sleeve (435); an inner tubular member (441) coaxially disposed about and slideably coupled to the inlet sleeve; and an outer tubular member (445) coaxially disposed about and slideably coupled to the outlet sleeve. The flexible fluid-cooled shaft (410) is in fluid communication with the inlet chamber (462) and the outlet chamber (463) of the housing, and the tubular sleeve member (489) is configured to house a portion of the flexible fluid-cooled shaft (410).

    摘要： A system including a catheter navigable to a location within a patient, a lumen extending through the catheter and ending at the distal end in an orifice, a fluid controller in fluid communication with the lumen of the catheter and capable of supplying a fluid to or removing a fluid from an area proximate the desired location. The control of the fluid in the area proximate the desired location affecting a dielectric constant of the area proximate the desired location. The system includes a microwave energy source, and a microwave ablation probe connected to the microwave energy source, the microwave ablation probe being navigable to a desired location within the patient. Application of energy from the microwave energy source to the microwave ablation probe in an area proximate the desired location having the affected dielectric constant results in a substantially spherical tissue effect in the area proximate the desired location.

    摘要： A treatment device comprises a housing (450A) defining an aperture on a proximal end thereof, an inlet chamber (462), and an outlet chamber (463). A tubular sleeve member (489) extends from a distal portion of the housing. A cable assembly (15) is disposed within the housing via the aperture. The cable assembly includes an inner conductor (220), an outer conductor (224), and a dielectric material (222) disposed between the inner conductor and the outer conductor. A fluid-cooled shaft (410) is slidingly coupled to the tubular sleeve member (489) of the housing and in fluid communication with the inlet chamber (462) and the outlet chamber (463) of the housing.
