Fluid-enhanced electrosurgery with integrated irrigation and aspiration

A method of performing electrosurgery, the method comprising:

• delivering, via at least one irrigation port defined by a distal portion of an electrosurgical device, a surgical fluid to a target treatment site within a patient;
• providing, via a first electrode extending distally from the distal portion of the electrosurgical device, a delivered electrical current to the target treatment site;
• receiving, via a second electrode extending distally from the distal portion of the electrosurgical device, a return electrical current from the target treatment site;
• and
• aspirating, via a central aspiration lumen defined by the first electrode and the second electrode, the surgical fluid from the target treatment site.

A medical system comprising:

• a generator configured to provide electrical energy;
• and
• an electrosurgical device comprising:
• a proximal portion comprising an electrical connector configured to electrically couple to the generator;
• a distal portion defining at least one irrigation port configured to distally deliver a surgical fluid to a target treatment site;
• a first electrode extending distally from the distal portion, the first electrode configured to provide a delivered electrical current to the target treatment site;
• and
• a second electrode extending distally from the distal portion, the second electrode configured to receive a return electrical current from the target treatment site;
• wherein the first electrode is oriented relative to the second electrode so as to define a central aspiration lumen between the first electrode and the second electrode, the central aspiration lumen configured to proximally withdraw the surgical fluid from the target treatment site.
