摘要：
Various embodiments of the invention provide a system for treating abnormalmucosa in an esophagus comprising an elongated member； an energy deliverystructure deployable from the elongated member and adapted to engage acircumferential section of a mucosal lining of the esophagus to deliver energyto the section； and means for delivering energy through the delivery structureunder conditions selected to initiate regrowth of a mucosal layer withoutsubstantial injury to a sub-mucosal layer underlying the mucosal layer. Byinjuring or necrosing metaplastic or other abnormal mucosal cells, regrowth ofthe mucosa substantially free from abnormal cells can be initiated. In anembodiment, the energy delivery structure can include an RF electrode arraypositioned on a surface of the structure and configured to be coupled to an RFpower supply.
