    摘要: A surgical instrument includes a sheath and an energy catheter. The sheath is configured to be inserted into a nasal cavity of a patient's head. The energy catheter includes a shaft and an end effector. The end effector is configured to selectively expand radially outwardly. The end effector includes an energy member that includes a flexible wire and electrodes disposed along the wire. The energy catheter is selectively translatable relative to the sheath. In a proximal position, the end effector is housed coaxially within the sheath to thereby prevent the end effector from radially expanding. In a distal position, the end effector is exposed from the sheath to thereby permit the end effector to expand for contacting tissue in the nasal cavity of the patient's head. When the end effector is in the expanded state, the end effector has a width and a length greater than the width.
