Devices and methods for controlling initial movement of an electrosurgical electrode
First Claim
1. A method for controlling the initial movement of an electrosurgical electrode of an electrosurgical device comprising:
- initiating the delivery of energy to an electrode;
monitoring an electrical characteristic associated with the electrosurgical electrode;
determining when an arc has been initiated based upon the monitoring step; and
moving the electrosurgical electrode once the arc has been detected.

Abstract
An electrosurgical electrode assembly having a cutting device including a catheter with a proximal and distal end, and an electrode carried on the distal end of the catheter. A controller is connected to the cutting device. A data acquisition system is connected to the controller and is capable of monitoring voltage and current output. A microprocessor may also be connected to the data acquisition system for processing voltage and current data from the data acquisition system. A generator is also connected to the data acquisition system. The controller initiates movement of the electrode upon arc initiation at the electrode. Methods of using the devices herein are also disclosed.
