Problems solved by technology
Although successful in several areas, radiofrequency ablation has several major drawbacks, including incomplete ablation, often lack of visualization during catheterization, potential overlap between treatments (where some areas receive twice as much energy as others ), tissue charring and need for frequent debridement, frequent need for additional doses of energy after debridement,

Embodiment Construction
[0139] figure 1 A perspective view of one example of a therapeutic assembly 10 positioned within a working channel 14 of an endoscope 12 (eg, an orally or nasally insertable scope) is shown. In this example, the treatment device 16 itself may utilize a first catheter 18 having an expandable or expandable balloon member 22 and a first catheter 18 that is freely slidable relative to the first catheter 18 and also has an inflatable balloon at its distal end. The second conduit 20 of the member 24 . The first conduit 18 as well as the second conduit 20 may have a fluid-tight and / or gas-tight seal 30 formed at the proximal end of the conduit. Inflatable and / or expandable members 22, 24 (shown in this example as inflated balloons) may be pressurized to effectively and safely occlude the chamber. The balloon may be filled with cooled or room temperature fluid to prevent possible damage from balloon rupture or leakage around the balloon. The pressure within the inflatable or expand...

Abstract
Methods and apparatus for the treatment of a body cavity or lumen are described where a heated fluid and/or gas may be introduced through a catheter and into treatment area within the body contained between one or more inflatable/expandable members. The catheter may also have optional pressure and temperature sensing elements which may allow for control of the pressure and temperature within the treatment zone and also prevent the pressure from exceeding a pressure of the inflatable/expandable members to thereby contain the treatment area between these inflatable/expandable members. Optionally, a chilled, room temperature, or warmed fluid such as water may then be used to rapidly terminate the treatment session.
