1. A method for accessing a treatment area in a patient, the method comprising:
advancing a distal end of a sinus access device in a straight configuration through a nostril into a nasal cavity;
sliding a first slider on a handle of the sinus access device to advance a curved shape memory member out of a distal end of a rigid tube of the sinus access device, thus allowing the curved shape memory member to assume a default curved shape outside of the rigid tube; and
sliding a second slider on the handle to advance a flexible tube of the sinus access device over the curved shape memory member and to the treatment area, wherein the flexible tube is sufficiently flexible to assume the default curved shape when it resides over the curved shape memory member.
