Claim:
1. An ablation device comprising: a tubular member having a proximal portion, a distal portion and a lumen extending at least partially therethrough, the tubular member having a first configuration and a second configuration, the tubular member comprises a conductive portion; a distal cap operably connected to the distal portion, the cap having a diameter that is smaller than a diameter of a distal end portion of an endoscope; a proximal ring connected to the proximal portion, the proximal ring comprising a first portion and a second portion spaced apart from the first portion on a circumference of the proximal ring, the proximal ring having a diameter greater than a diameter of the distal end portion so that the proximal ring is sized and shaped to fit over the distal end portion; a tensioning member operably connected to the distal cap; a pushing member operably connected to the proximal ring at the first portion on the circumference of the proximal ring and the proximal ring at the second portion being free from connection to the pushing member; and an over catheter having the pushing member at least partially extending through a lumen of the over catheter; wherein the proximal ring is movable relative to the distal cap to move the tubular member between the first configuration and the second confirmation.
