Embodiment approach

[0148] It is also understood that a variety of sheaths may be used to desirably guide lead 100 toward a target anatomy, such as a target DRG. For example, if Figure 27 As shown, an additional sheath 122' can be used with the delivery system 120 previously described. In this case, the additional sheath 122' can be advanced through the sheath 122, and the lead 100 can be advanced through the additional sheath 122'. The additional sheath 122' can have any desired curvature or can be substantially straight. Each of the sheath 122, the additional sheath 122', and the lead 100 can be advanced and retracted relative to each other. In some embodiments, the sheath is movable such that the distal end of the additional sheath 122' extends about 12-20 mm, typically about 15 mm, beyond the distal end of the sheath 122. This movement, combined with the shape of the delivery device (eg, curvature), provides greater maneuverability and greater variation in the angles at which the device c...

Abstract

Devices, systems and methods are provided for accessing and treating anatomies associated with a variety of conditions while minimizing possible complications and side effects. This is achieved by directly neuromodulating a target anatomy associated with the condition while minimizing or excluding undesired neuromodulation of other anatomies. Typically, this involves stimulating portions of neural tissue of the central nervous system, wherein the central nervous system includes the spinal cord and the pairs of nerves along the spinal cord which are known as spinal nerves. In particular, some embodiments of the present invention are used to selectively stimulate portions of the spinal nerves, particularly one or more dorsal root ganglions (DRGs), to treat chronic pain while causing minimal deleterious side effects such as undesired motor responses. The present invention provides systems for positioning a lead near a spinal nerve, the systems comprising a lead, a sheath having a curved distal end and adapted to receive the lead therein, and a stylet configured to be posisitoned within a stylet lumen of the lead.

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional Patent Application No. 61 / 144690, filed January 14, 2009, entitled "Stimulation Lead, Delivery System and Methods of Use," under 35 U.S.C. 119(e), and filed on October 16, 2009 Priority to U.S. Provisional Patent Application No. 61 / 252,270, entitled "Strain Relief Support for Lead Connection," filed on 11 July 2009, both of which are hereby incorporated by reference. [0003] Statement of rights to inventions made in federally sponsored research and development does not apply. [0004] Not applicable. References to Sequence Listings, tables, or computer program listing attachments submitted on CD-ROM. Background technique [0005] Applying specific electrical energy to the spinal cord to manage pain has been actively practiced since the 1960s. Application of electric fields to spinal nerve tissue is known to be effective in shielding some types of pain from the region of the bod...
