A pyrocarbon tip for a cardiac stimulator electrode is subjected to an anodic electrolytic treatment in which a strong, concentrated acid with oxidizing properties, or a mixture of two or more such acids, is used as the electrolyte. The treatment is carried out with a voltage greater than 1 V, preferably between 1 and 20 V, and with a current density greater than 3 mA/mm2, preferably between 30 and 40 mA/mm2. Pyrocarbon tips treated in this manner have very low bias voltages in use. |
