Patent ID: 8038670

Claim:
An electrosurgical device to treat tissue in a presence of radio frequency power and a fluid provided simultaneously from a distal portion of the device, the device having a proximal end and a distal end, comprising: a handle; a shaft extending from the handle, the shaft having a distal end; a fluid passage being connectable to a fluid source of the fluid; an electrode tip comprising a single metal contact element providing an electrode having a distal portion and a proximal portion, the distal portion of the electrode extending distally beyond the distal end of the shaft, the proximal portion of the electrode being contained within the shaft, the distal portion of the electrode comprising a domed distal end and a hook shape, each having an exposed, electrically conductive surface; and at least one fluid outlet opening in fluid communication with the fluid passage, wherein the at least one fluid outlet opening is located at the distal end of the shaft and is defined by the distal end of the shaft and a portion of the electrode adjacent the distal end of the shaft.
