<p>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.</p> |
