ABSTRACT:
The invention relates to a method for the manufacture of implantable electrodes of vitreous carbon with an electrode head and an electrode stem, by pyrolysis of cross-linked synthetic resins. Electrodes manufactured in accordance with such a method exhibit high surface quality. In accordance with embodiments of the disclosure, the electrode stem is manufactured in the form of a blank by hardening a resin precondensate, then the electrode head is cast onto the blank in a casting mold, using a resin precondensate, and is cross-linked. Subsequently hardening takes place and then the synthetic resin is converted into vitreous carbon by pyrolysis, and the electrode obtained in this manner may, if desired, be activated to provide the electrode with a microporous surface structure.
