A lead for connecting a source of electrical signals to an internal organ of the body. The lead includes a small diameter lead body of carbon filaments surrounded by a stiffening sheath. The stiffening sheath allows the lead with an attached electrode to be guided to the desired internal organ through the vascular system. After the electrode is properly positioned, the sheath is peeled away from the carbon filament lead means of longitudinal grooves extending the length of the lead. The external stiffening sheath eliminates the need for the carbon lead to have a hollow interior for accepting a stylet. The disclosed lead is of small diameter which is particularly advantageous for multiple lead systems.
