Abstract

The invention provides a method and system for precision placement of ablation apparatus. An ablation catheter having a plurality of electrodes and having a radius of curvature selected responsive to a size of a patient's tongue, is placed near to the tongue and offset from a gag-response region in the throat, preferably using an optical viewing apparatus and a view port in the catheter. The ablation catheter is coupled to a baseplate and to a measuring device for indicating an offset of a selected reference point of the ablation catheter from the baseplate. The baseplate is coupled to a reference body structure, such as the jaw, lips or teeth. In cases where multiple ablation operations are conducted, the ablation catheter (or a replacement ablation catheter) is coupled to the baseplate so that the selected reference point has the same distance from the baseplate, and thus from the reference body structure. The reference body structure is a selected region of the lips and teeth, and the baseplate is coupled thereto by filling that region with a dental cement or other quick-setting compound, so as to create a dental fixture which is fitted to the patient.
