Embodiment Construction

[0045] Figure 6 One embodiment of positioning the device 200 of the present invention to selectively stimulate multiple segments of the spinal cord S simultaneously (in this example, segments 1, 2, 3) is shown. The device 200 is shown positioned in the epidural space of the spine at a lateral distance from the midline M of the spine, with the device 200 aligned with the dorsal root ganglia DRG1, DRG2, DRG3. Accordingly, as indicated by shading, portions of the device 200 are aligned with and may selectively contact the DRG1 , DRG2 , DRG3 . These aligned segments provide targeted or selective stimulation of one or more of the DRG DRG1, DRG2, DRG3 while avoiding or reducing stimulation of surrounding tissues such as the ventral root VR1, VR2, VR3 .

[0046] As shown, the device 200 is electrically connected to a power source or implantable pulse generator (IPG) 202 implanted in the patient. Figure 6 An antegrade positioning of the device 200 is shown, but a retrograde appro...

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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Provisional Patent Application No. 60 / 873,464 (Attorney Docket No. 10088-706.101), filed December 6, 2006, which is hereby incorporated by reference for all purposes. [0003] Statement of Rights to Inventions Made in the Name of Federally Sponsored Research and Development [0004] Not applicable [0005] References to Addendums to "Sequence" Listings or Computer Program Listings Submitted by CD [0006] Not applicable technical field [0007] The present invention relates to grouped leads for spinal stimulation. Background technique [0008] The application of specific electrical energy to the spinal cord to control pain has been actively practiced since the 1960s. It is known that the application of an electric field to the nerve tissue of the spine can effectively mask certain types of pain transmitted from the area of ​​the body associated with the stimulated nerve tissue. ...
