ABSTRACT:
A catheter intended to be temporarily implanted in the epidural spaces of a person for relief of pain includes four circumferential ring electrodes connected to terminals by fine wires embedded in the side wall of the catheter for attachment to a conventional pulse generator and a hollow elongated body with an injection portal at the proximal end and an aperture at the distal end for continuously administering a pain-relieving agent in a liquid form. The agent may be a narcotic or anesthesia. Methods for treating pain using the catheter include electrical stimulation, the use of narcotics, or anesthesia, which can be administered in any order, or simultaneously as empirically determined to provide the best pain relief for each patient.
