First Claim
1. A fluid-assisted bipolar electrosurgical device to treat tissue in a presence of radio frequency energy and a fluid provided from the device, the device comprising:
- a malleable shaft assembly comprising a first shaft and a second shaft, a length of the first shaft and a length of the second shaft encapsulated in an outer member comprising a polymer, and at least a portion of the first shaft and at least a portion of the second shaft being malleable to be manually shapeable by a user of the device;
a first electrode and a second electrode projecting from an end of the malleable shaft assembly;
at least one fluid outlet to deliver the fluid to the tissue,the first electrode is retained at a distal end of the first shaft;
the second electrode is retained at a distal end of the second shaft;
the first electrode is laterally spaced from the second electrode a predetermined distance;
the outer member being configured to retain the first electrode and the second electrode stationary relative to each other at a predetermined orientation and lateral separation distance even if the shaft assembly is bent,wherein the first electrode and the second electrode are configured to slide across the tissue surface in the presence of the radio frequency energy and the fluid.
