ABSTRACT:
Apparatus and methods are provided for ablating body tissue using radio frequency (RF) energy. A catheter having a lumen for delivering fluid can be inserted into a patient's body. A porous member, which may be expandable, is attached to the distal portion of the catheter. The porous member defines an interior region in communication with the lumen, such that the interior region is capable of receiving electrolyte fluid delivered from the proximal portion of the catheter. An RF electrode is disposed in the interior region and is configured for coupling to a source of RF energy, whereby RF energy may be transferred from the electrode to selected tissue areas in a patient's body via electrolyte fluid delivered through the lumen and into the interior region of the porous member.
