Thin layer ablation apparatus

An ablation apparatus for ablating an inner layer in an organ of a body, comprising:

• an inflatable member with an exterior surface including a plurality of apertures that communicate with an interior that houses an electrolytic solution, the inflatable member selectively releasing electrolytic solution through the apertures at a flow rate that is dependent on a pressure applied to the inflatable member by the electrolytic solution;
• a conforming member with a conductive surface coupled to an RF energy source and a back side in surrounding relationship to the exterior of the inflatable member, the conforming member being made of a material that provides substantial conformity between the conductive surface and a shape of the inner layer of the organ and receives electrolytic solution from the inflatable member and delivers it out of the conductive surface, the conductive surface delivering electrolytic solution and RF energy to the inner layer;
• a circuit with segments positioned at one of on the conforming member or in the conforming member for delivering RF energy to selected sections of the inner layer;
• and
• a feedback device including an apparatus for detecting a characteristic of the inner layer, the feedback device connected to the RF power source to provide a controlled delivery of RF energy to segments of the circuit in response to the detected characteristic.
