Articulating Ionizable Gas Coagulator
First Claim
1. A method for coagulating tissue, comprising the steps of:
- providing an electrosurgical apparatus including;
an elongated flexible tube having a proximal end and a distal end and defining a longitudinal axis; and
at least one electrode mounted proximate to the tube for ionizing pressurized ionizable gas;
moving the distal end of the tube from a first position wherein the distal end is disposed in a generally parallel fashion relative to the tissue to a second position wherein the distal end directs pressurized ionizable gas flowing through the tube at an angle α
with respect to the longitudinal axis; and
igniting the pressurized ionized gas through the at least one electrode.

Abstract
A method for coagulating tissue is disclosed. The method includes the steps of providing an electrosurgical apparatus including: an elongated flexible tube having a proximal end and a distal end and defining a longitudinal axis and at least one electrode mounted proximate to the tube for ionizing pressurized ionizable gas. The method also includes the steps of moving the distal end of the tube from a first position wherein the distal end is disposed in a generally parallel fashion relative to the tissue to a second position wherein the distal end directs pressurized ionizable gas flowing through the tube at an angle α with respect to the longitudinal axis and igniting the pressurized ionized gas through the at least one electrode.
