Abstract
Abstract An apparatus reduces the volume of selected sections of a tongue. The apparatus includes a catheter means. An electrode means is at least partially positioned in an interior of the catheter means. The electrode means is configured to deliver sufficient electromagnetic energy to ablate an interior of the tongue without damaging a hypoglossal nerve of the tongue. An electrode advancement and retraction means is coupled to the electrode means to advance and retract at least a portion of the electrode means in and out of a selected tongue surface. A cabling means is coupled to the electrode means.
