Ablation devices for ablating a tissue are provided. The ablation device includes a first elongate shaft having a proximal portion, a distal portion and a lumen extending at least partially therethrough and a second elongate shaft having a proximal portion, a distal portion and a lumen extending at least partially therethrough. The first elongate shaft is coaxially positioned and longitudinally movable relative to the second elongate shaft. The ablation device further includes a mesh member including a proximal portion and a distal portion. The proximal portion of the mesh member is operably connected to the distal portion of the second elongate shaft and the distal potion the mesh member is operably connected to an inner surface of the distal portion of the first elongate shaft. The mesh member includes a conductive portion configured to contact a surface for ablation.
