Selective ablation system

A process for providing ablation to a hollow organ, comprising the steps of:

• providing an assembly comprising an expandable first balloon having a hollow inner region, a second balloon assembly comprising a hollow expandable region substantially located within the hollow region of the first balloon, at least one deployable active, electrically conductive probe and a third balloon comprising a hollow expandable region substantially located within the hollow expandable region of the second balloon;
• providing a tube having a first end and a second end, the tube comprising a hollow region defined between the first end and the second end;
• inserting the second end of the tube into the hollow organ;
• inserting the assembly through the hollow region of the tube and extending from the second end of the tube into the hollow organ;
• inflating the first compliant balloon assembly to expand the hollow organ;
• inflating the second balloon to substantially contact the first compliant balloon;
• inflating the third balloon to deploy the electrically conductive probe though the first compliant balloon and into contact with the hollow organ.

An apparatus, comprising:

• an expandable first balloon having a hollow inner region;
• a second balloon assembly comprising a hollow expandable region substantially located within the hollow region of the first balloon, at least one deployable, active, optionally electrically conductive, needle and an active element, which optionally comprises an electrical conductor, connected to the deployable, active needle and extending from the hollow expandable region;
• and
• a third balloon comprising a hollow expandable region substantially located within the hollow expandable region of the second balloon.

An apparatus, comprising:

• a body having an outer surface, the outer surface having a recessed region;
• at least one active, optionally electrically conductive, probe having a tip located on the body within the recessed region;
• an orifice extending from the recess region and through the body;
• and
• an energy conveying connection to the active probe.

An apparatus, comprising:

• an expandable balloon having an outer surface and a hollow inner region having an entrance;
• at least two electrically conductive probe traces located on the outer surface of the balloon, the electrically conductive probe traces having at least one defined probe region defined there between;
• and
• means for applying energy between the electrically conductive probe traces.
