1. An energy delivery device, comprising:
a catheter shaft; and
an ablation assembly coupled to the catheter shaft and including
a cooling element movable from a collapsed state to an expanded state, and
an intercartilaginous energy emitter including a plurality of electrodes circumferentially offset from one another about a longitudinal axis of the ablation assembly, the electrodes being configured to deliver energy to a plurality of target regions of an airway that are spaced apart from one another with respect to a longitudinal axis of the ablation assembly, and wherein the energy emitter and the cooling element are configured to cooperate to form intercartilaginous lesions which are spaced apart from surface tissue of the airway and positioned between cartilaginous rings of the airway
wherein a cooling channel of the energy emitter is separate from a chamber of the cooling element to enable independent delivery of a first coolant from the catheter shaft to the channel of the energy emitter and a second coolant to the chamber of the cooling element.
