Neurostimulation system
First Claim
1. A neurostimulation system for use in selectively stimulating a target dorsal root ganglion having a bulbous shape, comprising:
- a lead having a proximal end, a distal end and an electrode,wherein the distal end of the leadis advanceable through a percutaneous access catheter,is flexible so that the lead is advanceable through the percutaneous access catheter in a substantially straightened configuration, andonce advanced beyond a distal end of the percutaneous access catheter the distal end of the lead is wrappable lengthwise at least partially about the target dorsal root ganglion so as to conform to and thereby follow the bulbous shape of the target dorsal root ganglion, so that the electrode is positioned to selectively stimulate the target dorsal root ganglion;
a signal generator coupled to the electrode providing energy to selectively stimulate the target dorsal root ganglion; and
a controller configured to control an output of the signal generator.

Abstract
Some embodiments of the present invention provide neurostimulation 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 neurostimulation systems adapted for selective neurostimulation of one or more nerve 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.
