DEVICES, SYSTEMS AND METHODS FOR THE TARGETED TREATMENT OF MOVEMENT DISORDERS
First Claim
1. A method of treating a patient having a movement disorder comprising:
- presenting the patient having the movement disorder;
positioning a lead having at least one electrode within the patient so that the at least one electrode is disposed near a target dorsal root ganglion associated with the movement disorder; and
providing stimulation energy to the at least one electrode so as to selectively stimulate at least a portion of the target dorsal root ganglion so as to reduce a symptom of the movement disorder while providing no or imperceptible amounts of stimulation energy directly to a ventral root.

Abstract
Devices, systems and methods are provided for the targeted treatment of movement disorders. Typically, the systems and devices are used to stimulate one or more dorsal root ganglia while minimizing or excluding undesired stimulation of other tissues, such as surrounding or nearby tissues, ventral root and portions of the anatomy associated with body regions which are not targeted for treatment. The dorsal root ganglia are utilized in particular due to their specialized role in movement. It is in these areas that sensory fibers are isolated from motor fibers. Sensory fibers are involved in a variety of reflexes that are involved in movement control, and these reflexes can be utilized in the treatment of various movement disorders. Thus, by stimulating sensory fibers in these areas, fundamental reflexes can be affected to lessen the symptoms of movement disorders.

17. A method of treating a movement disorder of a patient comprising:
-
advancing a sheath having a curved distal end along an epidural space of the patient; positioning the curved distal end so as to direct a lead advanced therethrough toward a spinal nerve associated with the disorder; advancing the lead having at least one electrode through the sheath so that the at least one electrode is disposed near the spinal nerve; and providing stimulation energy to the at least one electrode so as to stimulate at least a portion of the spinal nerve in a manner which reduces a symptom of the movement disorder.

25. A stimulation system for treating a patient having a movement disorder comprising:
-
a lead having at least one electrode, wherein the lead is configured for implantation so as to position at least one of the at least one electrode adjacent a dorsal root ganglion associated with the movement disorder; and a pulse generator electrically connected to the at least one of the at least one electrode, wherein the pulse generator provides a signal to the at least one of the at least one electrode which stimulates at least a portion of the dorsal root ganglion so as to reduce a symptom of the movement disorder. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)

42. A system for treating a patient having a movement disorder, the system comprising:
-
a lead having at least one electrode, wherein the lead is configured to be positioned so that at least one of the at least one electrodes is able to stimulate at least a portion of a target dorsal root associated with the movement disorder; at least one sensor configured to sense a symptom of the movement disorder; and an implantable pulse generator connectable with the lead, wherein the generator includes electronic circuitry configured to receive information from the at least one sensor and provide a stimulation signal to the lead in response to the sensed symptom of the movement disorder, wherein the stimulation signal has an energy below an energy threshold for stimulating a ventral root associated with the target dorsal root while the lead is so positioned. - View Dependent Claims (43, 44, 45, 46, 47)
