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.

L'invention concerne un ensemble électrode électrochirurgicale comprenant un dispositif de coupe équipé d'un cathéter doté d'une extrémité proximale et d'une extrémité distale, et une électrode supportée par l'extrémité distale dudit cathéter. Un contrôleur est connecté au dispositif de coupe. Un système d'acquisition de données est connecté au contrôleur et est capable de surveiller une sortie de tension et de courant. Un microprocesseur peut également être connecté au système d'acquisition de données afin de traiter des données de tension et de courant provenant dudit système d'acquisition de données. Un générateur est également connecté au système d'acquisition de données. Le contrôleur lance le déplacement de l'électrode lors de l'amorçage d'un arc au niveau de ladite électrode. L'invention concerne également des procédés permettant d'utiliser les dispositifs précités.
