Electrosurgical Instrument
First Claim
1. An electrosurgical instrument for conveying electrosurgical power to tissue to achieve a predetermined electrosurgical effect, comprising:
- an electrically conductive element having a first section and a first tapered section terminating at a conductor edge; and
an insulation layer having a second tapered section overlaying the conductive element which tapers on a side of the first tapered section to expose the conductor edge forming a primary reaction region.

Abstract
An electrosurgical instrument is disclosed for simplifying making incisions and other treatments using electrosurgery. The electrosurgical instrument comprises a body having at least one conductive element that is surrounded by an insulation layer except at a conductor edge portion of the conductive element. The conductor edge portion and insulation layer each having unique geometric shapes and composition of the parts to reduce or eliminate the production of smoke and eschar and reduce tissue damage. The outer profile of the insulation layer and conductive element are configured to facilitate the flow of electrosurgical decomposition products away from the conductor edge where they are formed.
