04044774 is referenced by 167 patents and cites 5 patents.

A lead is disclosed for being inserted within a human or animal body for applying electrical stimulation to the spinal cord of the recipient, whereby selected pain is effectively relieved by the application of an electrical signal of selected frequency, pulsewidth and amplitude to the lead. In particular, the lead comprises a spherically-shaped, distal electrode adapted to be disposed near a selected segment of the spinal cord whereby maximum stimulation may be applied to the afferent nerves passing therethrough, a first conductor taking the form of a helically-wound coil extending from the distal electrode to a first tubular contact, and a second conductor disposed axially of the first-mentioned coil and forming an extension extending beyond the first-mentioned contact and terminated in a second tubular contact.
