摘要：
The present invention provides systems, apparatus and methods for selectively applying electrical energy to body tissue. A device is provided having an enclosure within an outer wall formed from an electrically-permeable material to allow for electrical energy to pass from the interior of the enclosure through the outer wall. The device further includes an electrode positioned within the interior of the enclosure and a fluid passage coupled to the enclosure for delivery of an electrically conductive fluid into the interior of the enclosure such that the electrically conductive fluid couples the electrode with the electrically-permeable section of the outer wall. The conductive fluid allows for the passage of electrical energy from the electrode through the fluid and the outer wall of the enclosure for treatment of tissue on or in a patient. In this manner, the electrode does not directly contact the tissue of the patient, which reduces the potential for collateral tissue damage or necrosis and/or excessive electric fields in the tissue.
