1. A method for applying RF energy in a nasal region of a human patient, the method comprising:
inserting a distal end of a surgical probe into a nasal cavity of a patient through a nostril of the patient in a low-profile delivery state, wherein the surgical probe comprises:
a shaft having a proximal portion and a distal portion, wherein the shaft is configured to locate the distal portion at a target site in a nasal cavity, and
a therapeutic assembly at the distal portion of the shaft, wherein the therapeutic assembly comprises a plurality of struts arranged in at least two branches radially spaced apart from each other when the therapeutic assembly is in an expanded state, and a plurality of electrodes disposed on the plurality of struts;
advancing the distal end of the surgical probe into the nasal cavity with the therapeutic assembly in the low-profile delivery state;
transitioning the therapeutic assembly from the low-profile delivery state to the expanded state;
positioning the therapeutic assembly in the expanded state at a target site proximate or inferior to a sphenopalatine foramen; and
applying radiofrequency (RF) energy with the plurality of electrodes to the target site to therapeutically treat at least one nasal nerve.
