(FR) DISPOSITIF DE RESECTION CHIRURGICALE
Abstract
(EN)
A surgical organ resection device comprising a plurality of elongate electrodes (4) for insertion into organ tissue, the electrodes being capable of operating in a bipolar manner, and an input for receiving a drive signal for driving the electrode, the elongate electrodes being arranged in a two- dimensional array and/or the device being arranged such that, in use, subsets of the elongate electrodes are driven in turn.
