Problems solved by technology

[0008] Treatments involving devices based on RF electrical energy have been described previously, where the electrodes are placed primarily at the tip of the device and are therefore limited in effective size due to the small diameter of the device required for access to the nasal passages.

Abstract

Systems and methods for turbinate reduction are provided. The present disclosure includes an electrosurgical apparatus for treating tissue at a target site. The apparatus has a shaft with a proximal end and a distal portion, the distal portion comprising a return electrode and electrode support. There is also at least one active electrode on the shaft distal portion, which has a proximal portion and a distal portion and a plurality of aspiration apertures disposed therebetween. These apertures are fluidly connected to a fluid aspiration cavity that is located within the electrode support, and the cavity is connected with a fluid aspiration element that is located along the shaft. The plurality of apertures vary in size and are generally arranged so that the larger sized apertures are disposed towards the electrode proximal portion and the smaller sized apertures are generally located towards the electrode distal portion.

Description

technical field [0001] The present invention relates generally to the field of electrosurgery and, more particularly, to surgical systems and methods that apply high frequency electrical energy to ablate, reduce and treat target tissue, such as tissue within the nasal region. The invention is particularly suitable for turbinate reduction surgery and as a treatment for excessive nasal drainage or dyspnea. Background technique [0002] The sinuses are air-filled cavities on the inside of the facial bones that open into the nasal cavity. Sinusitis is inflammation of the mucous membranes of one or more paranasal sinus cavities. Sinusitis is often associated with a viral or bacterial upper respiratory infection that spreads to the sinuses. When the sinus openings become blocked, the cavity fills, creating deep pain and pressure. Retronasal or nasal drainage, pressure nasal congestion, headaches, sinus infections, and nasal polyps are often the most associated with chronic sinu...
