Neurostimulation methods and systems
First Claim
1. A method of stimulating a target dorsal root ganglion of a patient, comprising:
- implanting at least one electrode in proximity to the target dorsal root ganglion; and
activating the at least one electrode to deliver neurostimulation energy to at least a portion of the target dorsal root ganglion, without passing the neurostimulation energy through an intervening physiological structure, to selectively stimulate at least a portion of the target dorsal root ganglion to create paresthesia in an area of the patient'"'"'s body.

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.

10. A method of stimulating a target dorsal root ganglion of a patient, comprising:
-
implanting at least one electrode in proximity to the target dorsal root ganglion so that the at least one electrode maintains its position in proximity to the target dorsal root ganglion throughout a body position change of the patient; and activating the at least one electrode to deliver neurostimulation energy to at least a portion of the target dorsal root ganglion, without passing the neurostimulation energy through an intervening physiological structure, to selectively stimulate at least a portion of the target dorsal root ganglion. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method of stimulating a target dorsal root ganglion of a patient, comprising:
-
implanting at least one electrode in proximity to the target dorsal root ganglion; and activating the at least one electrode to selectively stimulate at least a portion of the target dorsal root ganglion to create paresthesia in an area of the patient'"'"'s body, wherein activating the at least one electrode to selectively stimulate comprises providing stimulation energy below a threshold for stimulating a ventral root associated with the target dorsal root ganglion.

27. A method of stimulating a target dorsal root ganglion of a patient, comprising:
-
implanting at least one electrode in proximity to the target dorsal root ganglion; and activating the at least one electrode to selectively stimulate at least a portion of the target dorsal root ganglion to create paresthesia in an area of the patient'"'"'s body, wherein activating the at least one electrode to selectively stimulate comprises providing a stimulation energy which preferentially stimulates myelinated fibers over unmyelinated fibers. - View Dependent Claims (28, 29, 30, 31, 32)
