Claim 10:
11. An electrode assembly for an electrosurgical pencil, comprising:
an insulative core configured to support an active wire around a peripheral surface of the insulative core, the active wire electrically coupled to an active pin adapted for insertion within a distal end of the electrosurgical pencil;
a ground electrode operably coupled to a proximal end of the insulative core and adapted for insertion within the distal end of the electrosurgical pencil, the ground electrode including a radially compressible outer peripheral surface to facilitate retention of the electrode assembly within the distal end of the electrosurgical pencil;
an insulative material disposed between the active pin and the ground electrode and configured to at least partially encapsulate the active pin and electrically isolate the active pin from the ground electrode; and
a hypotube operably engaged to a proximal end of the insulative material and configured to at least partially encapsulate the active pin, wherein the ground electrode surrounds the hypotube and the insulative core.
