Abstract
A combined electrical and chemical stimulation lead is especially adapted for providing treatment to the spine and nervous system. The stimulation lead includes electrodes that may be selectively positioned along various portions of the stimulation lead in order to precisely direct electrical energy to ablate or electrically stimulate the target tissue. Embodiments of the stimulation lead include single or multiple lead elements. The multiple lead element embodiments can be selectively deployed to cover a targeted area. The lead may also includes central infusion passageway(s) or lumen(s) that communicates with various infusion ports spaced at selected locations along the lead to thereby direct the infusion of nutrients/chemicals to the target tissue. One embodiment utilizes a dissolvable matrix for infusion as opposed to remote delivery through an infusion pump.
