Abstract:
A method for testing a brain lesion electrode which is intended for use in treatment of a specified area in the brain, by controlled coagulation or lesioning, characterised by the following steps:a. introducing in a transparent container a solution of coagulatable protein with a predetermined salt content conforming with the salt content in a patient's body;b. sealing the container with a seal, which the brain lesion electrode can penetrate;c. heating the solution to a selected temperature in the range 35-40.degree. C.;d. introducing a tip of the brain lesion electrode into the container through the seal;e. supplying, during a selected period, current of a predetermined intensity and frequency between the brain lesion electrode and a backplate electrode in the container, the temperature of the solution in the area of the tip of the brain lesion electrode being raised and the solution being coagulated in a local area; andf. evaluating a test result by visual inspection of the coagulated local area.
