Abstract

An irrigated electrode assembly has a proximal portion with a proximal end and a distal portion with a distal end. The assembly includes a first conduit defining an irrigation channel and a second conduit, both of which extend from the proximal portion to the distal portion of the irrigated electrode assembly. A proximal and a distal emitter is located on the distal portion of the assembly with the distal emitter being positioned distally relative to the proximal emitter. A fluid irrigation port is defined by the proximal or distal emitter and is in fluid communication with the first conduit. An insulative spacer extends between a distal end of the proximal emitter and a proximal end of the distal emitter. An insulative body houses the first and second conduits and extends from the proximal portion of the irrigated electrode assembly to a proximal end of the proximal emitter.
