1. An electrosurgical needle 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 tip; and
an insulation layer having a second tapered section overlaying the conductive element and at least a portion of the first tapered section.

Abstract
An electrosurgical needle includes a body having at least one conductive element in the form of a needle that is surrounded by an insulation layer except at a conductor tip portion of the conductive element. The conductor tip portion and insulation layer each have unique geometric shapes and composition of the parts to reduce or eliminate the production of smoke and eschar and reduce tissue damage. The electrosurgical needle electrode is configured to concentrate the flow of electrosurgical energy at the tip region.

43. A sterile package kit for use in performing an electrosurgical procedure, comprising:
-
a sterile package; and
a disposable electrosurgical needle sealed within the sterile package, the disposable electrosurgical needle comprising an electrically conductive element having a first section and a first tapered section terminating at a conductor tip, and an insulation layer having a second tapered section overlaying the conductive element which tapers on all sides of the first tapered section to expose the conductor tip forming a primary reaction region. - View Dependent Claims (44, 45)
