The infusion array includes an RF electrode and at least a first and a second infusion member. Each infusion member has a tissue piercing distal portion and an infusion lumen. At least one of the first or second infusion members is positionable in the elongated delivery device in a compacted state and deployable from the elongated delivery device with curvature in a deployed state. Also, at least one of the first or second infusion members exhibits a changing direction of travel when advanced from the elongated delivery device to a selected tissue site. At least one infusion port is coupled to one of the elongated delivery device, the infusion array, the first infusion member or the second infusion member.
