Electrosurgical Blade With Profile For Minimizing Tissue Damage
First Claim
1. A electrosurgical blade for conveying electrosurgical energy to tissue to achieve a predetermined electrosurgical effect, comprising:
- an electrically conductive element;
an insulation layer overlaying the conductive element except at a conductor edge forming a primary reaction region solely along at least a portion of a leading edge of the electrosurgical blade; and
an electrical coupling surface for electrically coupling the electrically conductive element to a handle.

Abstract
An electrosurgical blade for use in electrosurgery includes 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 profile of the electrosurgical blade is configured to concentrate the flow of electrosurgical energy in a concentration region to facilitate starting or initiating the electrosurgical process. The profile of the electrosurgical blade is further configured to prevent excessive delivery of electrosurgical energy to reduce or eliminate the production of smoke and eschar and reduce tissue damage.
