Stimulation systems
First Claim
1. A stimulation system, comprising:
- a battery;
a pulse generator;
an electrical connection between the battery and the pulse generator; and
a lead connected proximally to the pulse generator and distally to an electrode sized and configured for implantation within a foramen and adjacent a dorsal root ganglion, the electrode driven by a signal from the pulse generator,wherein the signal is configured to stimulate a volume of tissues including at least a portion of the dorsal root ganglion in the immediate vicinity of the electrode while substantially excluding a ventral root,wherein the battery, the pulse generator, the electrical connection, the lead and the electrode are configured for implantation in the body in an arrangement wherein the lead passes through at least a portion of an epidural space while the pulse generator is disposed outside of the epidural space.

Abstract
Some 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. 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.
