LONG-ELECTRODE CONCEPT FOR DISCRETE CUTTING WITH RF ENERGY IN ELECTROSURGICAL APPLICATIONS

Abstract: an electrosurgical device for discretely cutting target tissue that is adjacent non-target tissue includes an elongate shaft having a proximal portion including a proximal end and a distal portion including a distal end. at least one electrode is configured to cut the target tissue. the at least one electrode has a surface area and is located on the distal portion. the distal portion is electrically insulated from the at least one electrode and has a surface area significantly larger than the surface area of the at least one electrode. the distal portion is configured to prevent movement of the distal portion into a cut or puncture formed in the target tissue by application of energy to the at least one electrode.
