1. A tissue desiccating electrode comprising:
- a first longitudinal member, having a proximal end and a distal end;
a second longitudinal member, having a proximal end and a distal end, wherein at least one of the first longitudinal member and second longitudinal member is a conductor; and
a tip member coupled to the first longitudinal member proximate the distal end thereof and coupled to the second longitudinal member proximate the distal end thereof, the tip member having a centrally positioned, transversely extending thermally conductive fixed protuberance, having an outer perimeter with an overall smoothly curved base and a plurality of cooling grooves, penetrating inwardly from the outer perimeter.

Abstract
A tissue desiccating electrode has first and second longitudinal members each with proximal and distal ends. A tip member couples the longitudinal members proximate the distal ends thereof and has a centrally-positioned, transversely-extending, fixed protuberance. The protuberance has an outer perimeter with an overall smoothly curved base and a plurality of cooling grooves. The grooves penetrate inwardly from the outer perimeter.
