Appeal No. 98-0194 Page 8 Application No. 08/132,940 Claim 13 recites the same elements as set forth in claim 1 but in addition thereto recites that (1) the clock sets units of time which are about a millisecond, and (2) the feedback signal is used to terminate the electrosurgical generator's supply of energy to the active and return leads by altering a drive circuit thereof. Claim 18 recites a method of automatically controlling an electrosurgical generator in response to the level of tissue impedance between active and return electrodes of the electrosurgical generator during tissue desiccation. The steps recited in claim 18 include, inter alia, (1) using an electrosurgical generator to supply energy to an active electrode and a return electrode; (2) setting the amount of energy desired for electrosurgery on a user control; (3) sensing the voltage level between the active and return leads; (4) sensing current flowing through the active or return lead; (5) calculating power flow with a multiplier receiving the sensed voltage level and current flow; (6) calculating with an integrator energy supplied through the leads per unit of timePage: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
