    • Implementations described and claimed herein provide paddle leads for dorsal root ganglia (DRG) stimulation and methods of implanting the same. In one implementation, the paddle lead has a small profile facilitating deployment into a target space in the neuroforamen dorsal to the DRG and below the vertebral lamina. A paddle body of the paddle lead may include a living hinge and/or a contoured profile to further facilitate implantation in the target space. For suture assisted deployment as well as to resist migration of the paddle lead once deployed, the paddle lead may include a suture loop configuration. The paddle lead further includes an electrode array having electrode contacts arranged in a two dimensional configuration pattern to create an electrical field optimized for stimulation of the DRG.
    • 本文描述和要求保护的实施方式提供了用于背根神经节(DRG)刺激的桨叶引线以及植入其的方法。 在一个实施方式中,桨叶导线具有小的轮廓,便于布署到DRG背侧和椎板下方的神经孔中的目标空间中。 桨叶引线的桨体可包括活动铰链和/或轮廓外形以进一步便于植入目标空间。 对于缝合辅助部署以及抵抗一旦展开的桨叶引线的迁移,桨叶引线可以包括缝合线环结构。 桨叶引线进一步包括电极阵列,该电极阵列具有以二维配置图案布置的电极触点,以产生针对DRG的刺激而优化的电场。
