INSTRUMENT AND METHOD FOR THE ENDOSCOPICALLY CONTROLLED SHORTENING AND/OR FRAGMENTATION OF STENTS LOCATED IN HOLLOW ORGANS

摘要

An instrument and a method are proposed for endoscopically controlled shortening and/or fragmentation of stents made from electrically conductive material situated in the gastrointestinal tract, in the tracheobronchial system or in other hollow organs. The instrument comprises an electrode device with an electrode for introducing a high-frequency current into at least one wire of the stent and/or to form electric arcs between the electrode and the at least one wire. Use of the instrument and the method results in little or reduced damage being caused by current and/or heat in tissues directly adjacent to the application site and in tissues remote therefrom.
