Patent ID: 8357155

Claim:
An electrosurgical blade for conveying electrosurgical power to tissue to achieve a predetermined electrosurgical effect, comprising: an active electrode having a first section, a first tapered section terminating at a first conductor edge, and a first electrical coupling surface for electrically coupling the active electrode to a handle; a first outermost insulation layer having a second tapered section generally following the contours of and overlaying the active electrode which tapers against a side of the first tapered section to expose the first conductor edge; a return electrode electrically isolated from the active electrode, the return electrode having a third section, a third tapered section terminating at a second conductor edge, and a second electrical coupling surface for electrically coupling the return electrode to the handle; a second outermost insulation layer having a fourth tapered section generally following the contours of and overlaying the return electrode which tapers against a side of the third tapered section to expose the second conductor edge; and a passive electrode electrically isolated from the active electrode and the return electrode, the passive electrode having a third electrical coupling surface for electrically coupling the passive electrode to the handle.
