ABSTRACT:
An electrosurgical apparatus for performing a surgical procedure on a target site, comprising a shaft having a distal end portion, the distal end portion comprising an active electrode including a fuse leg, the fuse leg adapted to break and disable the instrument upon applying a voltage differential between the active electrode and a return electrode for a predetermined amount of time. In another embodiment, the present invention is a method of performing an electrosurgical procedure on a target tissue, comprising: placing an electrosurgical instrument in close proximity to the target tissue, the electrosurgical instrument comprising an active electrode having a pre-selected portion adapted to break and disable the instrument upon applying a voltage differential thereto for a working time; and applying the voltage differential.
