Utilization of an active catalyst in a surface coating of an electrosurgical instrument
First Claim
1. An electrosurgical instrument for use with an electrosurgical generator, the electrosurgical instrument comprising:
- a hand piece configured to receive energy from the electrosurgical generator; and
a conductive tip adapted to receive the energy from the hand piece, the conductive tip comprising a coating, on at least a portion of the tip, which includes one or more catalytic particles, the catalytic particles having a diameter of about 1 nanometer to about 1 micron.

Abstract
Applying and utilizing a catalyst in a coating layer to enhance release of accumulated buildup on a surface. The catalyst is in the form of micro or nano-sized particles that are optionally mixed with a binder material and applied as a coating of at least a portion of a surface, such as an electrosurgical tip. The particles are located on the outer surface of the coating layer to be in direct contact with any buildup, such as eschar, that may have accumulated. An energy source, such as a heat source, a light source, a microwave source, or the like, is used to activate the catalyst in order to aid in the release of the accumulated eschar. The activated catalytic particles interact with the eschar constituents to break bonds that have occurred between the eschar and the surface of the electrode or tip, allowing the eschar to release from the tip.
