Abstract
In some embodiments, an electrosurgical device comprises an electrically conductive elongate member for traversing body vasculature defining a hollow lumen with one or more apertures at or near its distal end, wherein electrical energy can flow through the wall of the elongate member; and an energy delivery device in electrical communication with the elongate member located at or about the distal end of the elongate member. The energy delivery device includes an electrode for delivering energy, and a thermal shield positioned between the electrode and the elongate member.
Claims20
An electrosurgical device comprising:
- a flexible tubular elongate member defining an electrically conductive wall for delivering electrical energy therethrough, the elongate member further defining a lumen that is in fluid communication with at least one distal aperture;
- an energy delivery device including an electrode at a distal tip of the electrosurgical device, the electrode being distal to and spaced apart from the elongate member, the electrode being a first piece of metal and the elongate member being a second piece of metal wherein the first piece of metal and the second piece of metal are separate pieces of metal and not in contact with each other, and the electrode being in electrical communication with the electrically conductive wall of the elongate member by means of an intermediate conductive element;
- and an electrically and thermally insulative shield between the electrode and the elongate member.
