Methods for stimulating a dorsal root ganglion
First Claim
1. A method of pharmacologically modulating a dorsal root ganglion comprising:
- implanting an elongate body into an epidural space, wherein the elongate body has a conduit for delivery of a pharmacological agent;
advancing the elongate body along a nerve root and positioning an outlet of the conduit near the dorsal root ganglion associated with the nerve root; and
delivering a pharmacological agent from an implanted delivery device through the conduit so that the pharmacological agent pharmacologically modulates the dorsal root ganglion without pharmacologically modulating an associated ventral root, wherein the implanted delivery device comprises a reservoir for storing the pharmacological agent and a pump for moving the pharmacological agent from the reservoir to the conduit.

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.

9. A method of pharmacologically modulating a dorsal root ganglion comprising:
-
advancing a distal end of an elongate body along a portion of a peripheral nerve toward the dorsal root ganglion and a midline of a spinal column; implanting the distal end near the dorsal root ganglion; and delivering a pharmacological agent from an implanted delivery device through the distal end of the elongate body so that the pharmacological agent pharmacologically modulates the dorsal root ganglion, wherein the implanted delivery device comprises a reservoir for storing the pharmacological agent and a pump for moving the pharmacological agent from the reservoir to the elongate body. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
