Abstract
An apparatus, system, and method for treating body tissue includes an electrode assembly having a first electrode and a second electrode, with at least the first electrode formed of porous conductive material, such as porous metal. Conductive fluid is delivered to the operating site through the porous metal of the first electrode via a fluid supply conduit. The apparatus may also include a fluid withdrawal conduit. The second electrode may also be formed of porous metal, and may serve as the intake opening for the fluid withdrawal conduit. The electrode assembly may be positioned on a catheter shaft having a distal end, with the first electrode positioned on the catheter shaft distal end. In treating desired tissue at a selected operational site, the electrode assembly is introduced to the site with the first electrode positioned adjacent to the desired tissue. Conductive fluid, such as a saline solution, is delivered to the operational site via the supply conduit. Electrical power is provided across the first electrode and second electrode via a power supply, which may be an RF power supply.
