Patent ID: 7118569

Claim:
An electrode assembly for use with an electrosurgical instrument comprising: an elongate flexible shaft having a proximal end and a distal end; a first electrode located within the shaft having a distal end and proximal end, the distal end of the first electrode being formed as a working element to apply electrical energy to a body of a patient; a second electrode located within the shaft having a distal end and a proximal end; the distal end of the second electrode being formed as a working element distally spaced from the first electrode, the second electrode being electrically insulated from the first electrode; a current return contact connected to the proximal end of the second electrode; a power contact located at the proximal end of the shaft directly connected to the proximal end of the first electrode, wherein the proximal end of the first electrode is affixed to the power contact with a friction fit, the power contact adapted to removably couple with a power connection for a medical instrument; and wherein the shaft includes separate first and second lumens, the first electrode is located in one of the first or second lumens and the second electrode is located in the other of the first and second lumens.
