Neurostimulation system and method for providing therapy to patient with minimal side effects
First Claim
1. A method of providing therapy to a tissue region of a patient using first and second electrodes, comprising:
- conveying an electrical pulsed waveform between the first electrode and a stimulation site of a spinal cord of the patient, thereby evoking the antidromic propagation of action potentials along at least one sensory neural fiber of the spinal cord that creates a therapeutic effect in the tissue region, and evoking the antidromic propagation of action potentials along at least another sensory neural fiber that potentially creates a side-effect in another tissue region of the patient; and
conveying electrical energy between the second electrode and a blocking site of the spinal cord caudal to the stimulation site, thereby blocking the antidromically propagated action potentials along the at least other sensory neural fiber and reducing the side-effect that would have otherwise been caused in the patient in the absence of the conveyed electrical energy.

Abstract
A method comprises conveying a pulsed waveform between an electrode and a stimulation site of a spinal cord, thereby evoking the antidromic propagation of action potentials along a first sensory neural fiber creating a therapeutic effect in the tissue region, evoking the orthodromic propagation of action potentials along the first sensory neural fiber potentially creating paresthesia corresponding to the tissue region, and evoking the antidromic propagation of action potentials along a second sensory neural fiber potentially creating a side-effect in another tissue region. The method further comprises conveying electrical energy between an electrode and a blocking site rostral to the stimulation site, thereby blocking the action potentials propagated along the first sensory neural fiber and reducing the paresthesia, and conveying electrical energy between an electrode and a blocking site caudal to the stimulation site, thereby blocking the action potentials propagated along the second sensory neural fiber and reducing the side-effect.
