Abstract

A device for radio frequency ablation (RFA) of diseased tissue has

a mesh or plate with a grid of holes for holding electrodes;a plurality of electrodes with adaptable active tip length;means for visualizing and probing insertion depth of each of the electrodes in the diseased tissue;a switch box, connectable to the electrodes and adapted to distribute current between the electrodes during the RFA process;a control unit for controlling the switch box; andmeans for monitoring the RFA process.The control unit is adapted to determine groups of electrodes, an electric mode for activation of each group of electrodes, a polarity for electrodes within each group of electrodes, an activation mode for the groups, a time interval and order for activation of the groups, a power output and current strength, and a duration of the RFA process.
