Abstract: Electrode assemblies and associated systems employ a nonporous wall (22) having an exterior for contacting tissue. The exterior peripherally surrounds an interior area. The wall is essentially free of electrically conductive material. The wall is adapted to assume an expanded geometry having a first maximum diameter and a collapsed geometry having a second maximum diameter less than the first maximum diameter. The assemblies and systems include a lumen (34) that conveys a medium containing ions into the interior area. An element free of physical contact with the wall couples the medium within the interior area to a source of electrical energy to enable ionic transport of electrical energy from the source through the medium to the wall for capacitive coupling to tissue contacting the exterior of the wall.

Abstract: Systems for ablating body tissue comprise a family of electrode assemblies. Each electrode assembly (22) includes an extruded wall carrying an amount of electrically conductive material co-extruded within it. The extruded walls possess different electrical resistivity values by virtue of different amounts of electrically conductive material co-extruded within the walls. The systems also include means for specifying, among the family, use of the electrode assemblies according to a function that correlates desired tissue ablation effects with electrical resistivity values of the walls.
