A medical device may include a sheath, and an elongate member disposed within a distal portion of the sheath, the elongate member configured to reciprocally move between a sheathed configuration and a deployed configuration. The elongate member may be substantially linear and disposed within the sheath while in the sheathed configuration and extend distally from the sheath in a first direction in the deployed configuration. The elongate member may include a first bend disposed distal to the distal portion of the sheath, the first bend directing the elongate sheath in a second direction that is substantially opposite to the first direction, and a second bend distal to the first bend, the second bend directing the elongate sheath in a third direction substantially transverse to the first and second directions. The elongate member may also include a third bend distal to the second bend, the third bend directing the elongate member in approximately the first direction, and a first elongate portion disposed between the second and third bends. The elongate member may also include a second elongate portion distal to the third bend, and at least one electrode.
