Fluid-Assisted Medical Devices, Systems and Methods

An electrosurgical device comprising:

• a shaft having a proximal end and a distal end;
• at least one fluid lumen longitudinally extending through the shaft;
• and
• a plurality of electrodes carried by the distal end of the shaft, each of the electrodes including a porous structure in fluid communication with the at least one fluid lumen, the plurality of electrodes having a substantially co-extensive surface.

An electrosurgical device comprising:

• a shaft having a proximal end and a distal end;
• at least one fluid lumen longitudinally extending through the shaft;
• a first electrode carried by the distal end of the shaft and having a porous structure in fluid communication with the at least one fluid lumen, the first electrode having a distal end surface extending along a plane;
• and
• a second electrode carried by the distal end of the shaft and having a porous structure in fluid communication with the at least one fluid lumen, the second electrode having a distal end surface extending along the plane of the first electrode distal end surface.
