1. A system for ablating abnormal tissue from a human esophagus, comprising:
- a. energy distribution means capable of distributing radio frequency energy, microwave energy, ultraviolet light energy or thermal energy, transmitted from a heated fluid medium;
adapted for use with an expandable member shaped for insertion into and positioning in a human esophagus;
b. power means for powering the energy distribution means at levels appropriate to ablate human tissue within a human esophagus; and
c. control means designed for accurate control and positioning of the member.

Abstract
An ablation catheter system and method of use is provided to endoscopically access portions of the human esophagus experiencing undesired growth of columnar epithelium. The ablation catheter system and method includes controlled depth of ablation features and use of either radio frequency spectrum, non-ionizing ultraviolet radiation, warm fluid or microwave radiation, which may also be accompanied by improved sensitizer agents.
