First Claim
Patent Images
1. A method for stimulating a plurality of dorsal root ganglia comprising:
- positioning a lead within an epidural space, wherein the lead has a longitudinal axis and at least two electrodes disposed along the longitudinal axis;
aligning the lead so that each of the at least two electrodes is disposed within a distance of one of the plurality of dorsal root ganglia which allows selective stimulation thereto; and
electrically energizing the lead so as to provide selective stimulation to at least one of the plurality of dorsal root ganglia.

Abstract
Devices, systems and methods are provided for simultaneously stimulating the spinal anatomy at various target locations, such as spinal levels, along the spinal cord. In some embodiments, the devices, systems and methods stimulate the various spinal levels at specific nerve anatomies, such as the dorsal root DR or more specifically the dorsal root ganglion DRG. Optionally, the devices, systems and methods may be used to stimulate a single DRG or other anatomies.

5. A telescoping lead for stimulation of a nerve within tissue of a body, the telescoping lead comprising:
-
an elongate tubular body having a proximal end, a distal end, a lumen therethrough, and at least one electrode disposed thereon; an inner structure having a proximal end, a distal end, and at least one electrode disposed thereon, wherein the inner structure is advanceable through the lumen so that its distal end extends beyond the distal end of the elongate tubular body, and wherein the inner structure has a strength member extending between its proximal and distal ends so as to provide sufficient strength to allow tunneling of the lead through the tissue. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14)

15. A method for stimulating at least one dorsal root ganglion, the method comprising:
-
advancing a telescoping lead toward a dorsal root ganglion, wherein the telescoping lead comprises an elongate tubular body having a proximal end, distal end, a lumen therethrough and at least one electrode disposed thereon and an inner structure having at least one electrode disposed thereon, wherein the inner structure is advanceable through the lumen so that its distal end extends beyond the distal end of the elongate tubular body; and positioning at least one of the at least one electrodes near the dorsal root ganglion so as to apply stimulation to the dorsal root ganglion. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
