Claim:
1. A device for applying radiofrequency energy for sphincter treatment comprising: a flexible outer tube; an expandable basket having a at least first and second arms movable from a collapsed position to an expanded position, the first arm having a first opening formed therein and the second arm having a second opening formed therein; a plurality of electrodes movable with respect to the plurality of arms, the plurality of electrodes movable from a retracted position to an extended position such that one electrode of the plurality of electrodes is extendable through the first opening and another electrode of the plurality of electrodes is extendable through the second opening; an advancer slidably disposed within the flexible outer tube, the plurality of electrodes operably coupled to the advancer such that movement of the advancer advances the plurality of electrodes to the extended position; and an elongated spacer positioned within the flexible outer tube, the spacer having a central lumen to receive the advancer and to maintain a central position of the advancer as the advancer is advanced within the central lumen, the spacer further having an outer wall with at least one slit formed therein to form a closable flap for insertion of at least one wire inside, the flap openable to enable access for placement of the at least one wire inside the spacer and closable to retain the at least one wire inside the spacer.
