The present invention provides for regulating power supplied to an electrosurgical instrument used in conjunction with a distension medium. The pressure of the distension medium is closely monitored. Vapor bubbles (60) that occur in normal operation in some instruments or unexpectedly occur in other electrosurgical instruments directly affect the pressure of the distension medium. If the pressure increases beyond normal levels as a result of the vapor bubble (60), the power supplied to the electrosurgical element may be reduced or simply terminated until the pressure returns to an acceptable level. |
