(57) ABSTRACT

An ablation device including a handle portion, a shaft and at least one cable. The shaft extends distally from the handle portion and includes an inner conductor and an outer conductor that substantially surrounds at least a portion of the inner conductor. The cable extends from the handle portion along at least a portion of the shaft. The distal tip of the inner conductor is positionable distally beyond a distal-most end of the outer conductor. In response to movement of the at least one cable relative to the handle portion, the distal tip of the outer conductor is movable form a first position where the distal tip is substantially aligned with a longitudinal axis defined by the outer conductor to at least a second position where the distal tip is disposed at an angle relative to the longitudinal axis.
