Electrosurgical method
First Claim
1. A method for intra-procedurally assessing a likelihood of failure of a treatment procedure, the treatment procedure comprising delivering energy to a body of a human or animal using an electrosurgical generator, a treatment parameter being associated with the treatment procedure, the treatment parameter having a pre-set threshold associated with a successful treatment procedure, and a ramp time being defined for the treatment parameter to reach the pre-set threshold during the treatment procedure, the ramp time having a pre-set limit, the method comprising:
- measuring the treatment parameter over time from a start of the delivering of energy and during a course of the treatment procedure; and
during the course of the treatment procedure, determining whether or not the treatment parameter will reach the pre-set threshold such that the treatment procedure is likely to be successful, by correlating the measured treatment parameter with the ramp time;
whereby a likelihood the treatment procedure will fail may be determined if the treatment parameter does not reach the pre-set threshold prior to the ramp time reaching the pre-set limit; and
after the delivering of the energy for the ramp time has ended, adjusting an overall procedure time when the treatment parameter does not reach the pre-set threshold prior to the ramp time.

Abstract
Methods are disclosed for delivering energy to a body of a human or animal during a treatment procedure using an electrosurgical generator, a pre-set overall procedure time being defined for the treatment procedure, a ramp time being defined for a parameter to reach a pre-set threshold during the treatment procedure, the method comprising: measuring the parameter over time; and if the parameter has not substantially reached the pre-set threshold by the ramp time, setting a procedure extension time responsive to the time difference between the ramp time and the time at which the pre-set threshold was reached, and extending the overall procedure time by the procedure extension time.
