| abstract |
In an ESV a control system responds to impedance and temperature as sensed between and at the electrodes (13) during desiccation each of such electrodes being provided separately and independently through a suitable multiplexer with a specifically controlled RF power. An instantaneous impedance monitor senses impedance variations and controls by means of specific derivative sensitive algorithm part of a feedback loop, the output power delivered through each electrode. A further temperature dependent feedback loop power control system is operative in a multiplexed mode in pair with the above impedance feedback system. Such second system uses an array of temperature sensors placed in the immediate proximity of the each tissue contacting electrode, and an appropriate derivative sensitive algorithm. Both systems are operated in a multiplex mode through a first multiplexer. A second multiplexer shifts the output power to the various electrodes independently and separately. |
