Method and system for stimulating a dorsal root ganglion
First Claim
1. A method of stimulating a dorsal root ganglion comprising:
- advancing an electrode substantially adjacent to a portion of a peripheral nerve toward the dorsal root ganglion and a midline of a spinal column without crossing the midline of the spinal column;
implanting the electrode in proximity to the dorsal root ganglion; and
activating the electrode to stimulate a portion of the dorsal root ganglion.

Abstract
Some embodiments of the present invention provide a pulse generator for high impedance electrodes as well as stimulation systems and components for selective stimulation and/or neuromodulation of targeted neural tissue. Targeted neural tissue may include one or more dorsal root ganglia with an electrode implanted on, in or around a dorsal root ganglia. Some other embodiments of the present invention provide methods for selective neurostimulation of one or more dorsal root ganglia as well as techniques for applying neurostimulation to the spinal cord. Still other embodiments of the present invention provide stimulation systems and components for selective stimulation and/or neuromodulation of one or more dorsal root ganglia through implantation of an electrode on, in or around a dorsal root ganglia in combination with a pharmacological agent.
