Abstract
A method and a device for testing a brain lesion electrode (1) which is intended for use in treatment of a specified area in the brain, for instance, by controlled coagulation or lessening. The device comprises a transparent container (2) which in adapted to accommodate a solution of coagulatable protein with a predetermined salt content, a seal (6), which the brain lesion electrode (1) can penetrate and which is adapted to seal the container (2) containing the solution, a heating device (3) for heating the solution to a selected temperature, a power unit (23) for supplying, during a selected period, current of a predetermined intensity and frequency between the electrode (1) and a backplate electrode (18) in the container (2) to increase the temperature of the solution in the area at the tip of (21) of the electrode when the electrode (1) is introduced into the solution and positioned therein.
