Abstract
An electrosurgical system includes an RF current generator, a handle body, and an end effector. The end effector may include a first and a second energy delivery surface. At least a portion of either first or second energy delivery surfaces, or both, may include one or more patterned coatings of an electrically non-conducting non-stick material. The material may be deposited on a surface of, within a depression in, or on features extending from the energy surfaces, or through an overmolding process. The patterned coating may be formed from a coating of the material from which portions have been removed. An energy delivery surface has a first area, and the patterned coating has a second area. A ratio of the second area to the first area may be less than or equal to about 0.9, less than or equal to about 0.7, or less than or equal to about 0.5.
