US 2006/0052826 A1 · Pulse generator for high impedance electrodes

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.
