1. A combined electrical and chemical stimulation device comprising:

  • a stimulation lead having an elongated, 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 second 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 chemical/nutrients from the second lumen to tissue located exterior of said stimulation lead, said plurality of first infusion ports not communicating with said second lumen and said plurality of second infusion ports not communicating with said first lumen; 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.
