An ablation apparatus has a balloon that is inserted into an organ of a body and ablates all or a selected portion of the inner layer of the organ. Electrolytic solution fills the balloon, and the balloon includes a plurality of apertures from which electrolytic solution flows from the balloon. The flow rate of electrolytic solution is dependent on the pressure applied to the balloon by the electrolytic solution. A conforming member, with a conductive surface and a back side, is made of a material that substantially conforms to a shape of the inner layer of the organ and delivers the electrolytic solution and RF energy through the conductive surface to the inner layer. Advantageously, difficult to access areas are reached with the inclusion of the conforming member. Optionally positioned between the conforming member and the balloon is a porous membrane. A printed circuit is printed in or on the conforming member and delivers RF energy to selected sections of the inner layer. The printed circuit provides for the monitoring of impedance, temperature and circuit continuity. Additionally, the printed circuit can be multiplexed.
