Claim 0:
1. A method for improving a patient's sleep by treating at least one of rhinitis, congestion, and rhinorrhea within a sino-nasal cavity of a patient, the method comprising:
advancing a multi-segment end effector into the sino-nasal cavity of the patient, the multi-segment end effector being operably associated with a shaft of a treatment device and configured for delivering energy to one or more target sites within the sino-nasal cavity of the patient, the multi-segment end effector comprising a first segment that is spaced apart from a separate and distinct second segment along a length of the shaft, wherein each of the first and second segments is transformable between a retracted configuration and an expanded deployed configuration and comprises a respective architecture in the expanded deployed configuration, wherein the first segment comprises:
a first set of flexible support elements that each comprises an array of electrodes positioned at separate and discrete portions thereon and the first segment is transformable between a retracted configuration and an expanded deployed configuration, the first set of flexible support elements extend in a first outward direction relative to a longitudinal axis along which the shaft lies and are positioned within a first half of the first segment and cooperatively form an inwardly extending first concave shape when the first segment is in the expanded deployed configuration to complement anatomy at a first location within the nasal cavity; and
a second set of flexible support elements that each comprises an array of electrodes positioned at separate and discrete portions thereon and extend in a second outward direction relative to the longitudinal axis and substantially opposite the first outward direction and are positioned within a second half of the first segment and cooperatively form an inwardly extending second concave shape opposing the first concave shape when the first segment is in the expanded deployed configuration; and

deploying at least the first segment at a respective first location within the nasal cavity; and
delivering energy, via one or more of the electrodes, to one or more target sites at the first location within a sino-nasal cavity of the patient to disrupt multiple neural signals to, and/or result in local hypoxia of, mucus producing and/or mucosal engorgement elements, thereby reducing production of mucus and/or mucosal engorgement within a nose of the patient and reducing or eliminate one or more symptoms associated with at least one of rhinitis, congestion, and rhinorrhea to improve nasal breathability of the patient.
