ELECTROSURGICAL DEVICE HAVING A LUMEN

摘要

In some embodiments, an electrosurgical device comprises: an electrically conductive elongate member for traversing body vasculature wherein electrical energy can flow through the wall of the elongate member; the elongate member defining a hollow lumen with one or more apertures at or near its distal end; and an energy delivery device in electrical communication with the elongate member (i.e. with the wall defining the lumen) at or about the distal end of the elongate member. The energy delivery device includes an electrode for delivering energy and a thermal shield is positioned between the electrode and the elongate member.
