1. A combined electrical and chemical stimulation device especially adapted for inserting within an intervertebral disc for treatment of target tissue therein, said device comprising:

  • a stimulation lead having an elongate, tubular configuration, and a first lumen extending therethrough;

    a plurality of first infusion ports communicating with said first lumen, said first infusion ports enabling infusion of chemicals/nutrients from the first lumen to tissue located exterior of said stimulation lead;

    a second lumen extending through said stimulation lead and spaced from said first lumen, said second lumen terminating at a location on said stimulation lead between a proximal and a distal end of said stimulation lead, said first lumen extending beyond said first lumen toward said distal end of said stimulation lead;

    a plurality of second infusion ports communicating with said second lumen, said second infusion port enabling infusion of chemicals/nutrients from the second lumen to tissue located exterior of said stimulation lead; and

    a plurality of electrodes positioned on said stimulation lead and between said first and second infusion ports, said electrodes communicating with a source of electrical energy for providing electrical stimulation of tissue adjacent said electrodes.
