1. A lead for percutaneous insertion into an epidural space of a spinal canal, the lead comprising:

  • a) an elongated lead body having opposed proximal and distal end portions, wherein the distal end portion is adapted for movement between a first state in which the distal end portion has a generally linear configuration and a second state in which the distal end portion has an undulating configuration;

    b) at least one electrode operatively associated with the distal end portion of the lead body for stimulating a patient;

    c) connector means operatively associated with the proximal end portion of the lead body for connecting to a signal generator; and

    d) conductor means extending through the lead body for conducting signals between the at least one electrode and the connector means, and whereby the generally linear configuration of the first state facilitates insertion of the lead into the epidural space and the undulating configuration of the second state allows the distal end portion of the lead body, once situated within the epidural space, to exert outward force on structures of the spinal canal, thereby affixing the lead within the spinal canal.
