Systems and methods for electrosurgical sinus surgery

摘要

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.
