摘要：
A method and apparatus for ablating at least a portion of a nasal concha. The apparatus includes a catheter having a distal portion with a dimension configured for positioning through a nostril of a patient into a nasal meatus adjacent a nasal concha, and an energy delivery device coupled to the catheter distal portion including one or more energy delivering probes extendable from the catheter distal portion a sufficient distance to be inserted into an interior of the nasal concha to deliver ablative energy therein. The distal portion of the apparatus may also include an expandable member, expansion of the expandable member within the nasal meatus immobilizing the distal portion within the nasal meatus.
