1. A method for treating tissue in a body lumen within a patient'"'"'s nose comprising:
- introducing an electrode terminal through an opening in the patient'"'"'s head into the nasal cavity;
advancing the electrode terminal into a body lumen coupled to a sinus cavity;
applying sufficient high frequency voltage to the electrode terminal to remove at least a portion of the occlusive media within the body lumen and to convert solid occlusive media molecules into non-condensable gases; and
aspirating the non-condensable gases from the body lumen.

Abstract
The present invention provides systems and methods for selectively applying electrical energy to a target location within the head and neck of a patient'"'"'s body, particularly including tissue in the ear, nose and throat. The present invention applies high frequency (RF) electrical energy to one or more electrode terminals in the presence of electrically conductive fluid to remove and/or modify the structure of tissue structures. The present invention is particularly useful for removing occlusive media within the small body passages connected to sinus cavities within the patient'"'"'s nose to treat chronic sinusitis.
