A method of treatment of nasal conditions comprising: delivering an expandable structure in a crimped configuration to a nasal lumen; expanding the expandable structure within the nasal lumen to a stable expanded configuration; removing the structure from the nasal lumen, after a time period, where removing comprises causing the structure to self-crimp. The expandable structure optionally comprises: a first shape memory (SM) portion which is in a strain-induced state; and a second portion which resists expansion of said structure due to said first portion, over a plurality of different expansion states of said first portion. Optionally, the properties of the second portion vary over its cross section. For example an outer surface and/or peripheral layer may have desirable environmental resistance properties and/or a frame may have desirable mechanical properties, for example a high creep resistance.
