摘要：
A vessel sealing device having a pair of electrodes that are maintained in spaced apart configuration when closed by non-uniform coating formed from a non-conductive material that has been applied to roughened electrodes so that the coating allows for the passage of a predetermined amount of radiofrequency (RF) energy between the electrodes. The coating has a predetermined thickness that spaces the electrodes apart while also having the predetermined non-uniformity that allows RF energy to pass between the electrodes when a vessel is trapped therein, thus desiccating the vessel positioned in the jaws. The electrodes may include a series of grooves in a herringbone pattern, with each electrode having the pattern oriented in the same direction or in opposite directions.
