Implantable lead

摘要

An implantable neural stimulator lead for introduction to and fixation in the epidural space of a patient includes an electrical conductor coated with a non-conductive coating and having a contact region thereon including an electrode for stimulating the patient's spinal cord through the dura. The contact region is located substantially intermediate the distal ends of the lead, whereby the lead may be installed and fixed in the epidural space by manipulation of both ends of the lead. A second surrogate lead is also provided for coupling to an end of the stimulator lead to enable the stimulator lead to be pulled into a position in the patient's body where stimulation is to be effected. One end of the surrogate lead includes a groove to facilitate snaring with a looped snare.
