Method for making an electrical contact for a vitreous carbon electrode

A method of producing an electrical contact for a vitresous carbon electrode comprising the steps of:

• producing an electrode blank of a cross-linked artificial resin, said resin having a pyrolyzing temperature associated therewith at which said resin becomes pyrolyzed;
• producing a longitudinally extending bore terminating blank, said bore having an inner dimension;
• providing a pin composed of biocompatiblep metal having a melting point higher than said pyrolyzing temperature, and having an outer outer dimension smaller than said inner dimension of said bore;
• introducing said sleeve into said bore with respective portions of said sleeve projecting from opposite sides of said electrode blank;
• and
• pyrolyzing said electrode blank with said sleeve introduced therein at said pyrolying temperature and thereby cross-linking said artificial resin to convert said artificial resin into vitreous carbon and to shrink said electrode blank onto said sleeve.
