1. A method of therapeutic treatment of a living body, comprising the steps of:

  • implanting into the body a flexible electrode consisting of multiple woven strands of tiny individual elongate uninsulated fibers composed of non-metallic substantially isotropic electrically conductive material electrically connected to a current-carrying lead, to form an electron-ion interface with blood and/or body tissue for efficient transfer of electrical energy along an entire substantial length of uninsulated surface of the fibers, in which the cumulative fiber surface presents an effective surface area considerably greater than the apparent actual surface area calculated from the linear dimensions of the electrode, andtransmitting electrical impulses through the lead to the electrode at one side of said electron-ion interface to deliver electrical energy from the impulses to the other side of the interface with rapid initial rise times as a consequence of the electrical characteristics of the interface.
