摘要

An energy delivery system and a method of delivering energy to a tissue are provided. The energy delivery system includes an overtube. The overtube includes a body having a proximal portion, a distal portion and a lumen extending at least partially therethrough. The proximal portion is adapted to be positioned over a distal portion of an endoscope. The overtube includes a plurality of openings formed in the body and connected to the lumen and an electrode portion fixed in a position on an outer surface of the body and extending over at least a portion of the outer surface of the body. The lumen is operably connectable to a vacuum source and the electrode portion is operably connectable to a power source.
