    • A lead delivery system for delivering a neurostimulation lead to a patient's internal jugular vein using a percutaneous stick. The system comprises a neurostimulation lead adapted to stimulate a vagus nerve from the internal jugular vein. The lead includes a proximal end, a distal end, a generally spiral shaped retaining structure interposed between the proximal and distal ends and configured to retain the lead in the internal jugular vein, an electrode coupled to the retaining structure, and a side port interposed between the retaining structure and the proximal end. The side port provides access to a lumen extending from the distal end to the side port. A guidewire is sized to fit within the side port and lumen and reduce a force exerted by the retaining structure against the internal jugular vein, thereby allowing rotation of the lead and orientation of the electrode by applying a torque to the lead. A catheter has a lumen sized to slideably receive the medical electrical lead and configured to provide access to the internal jugular vein from the percutaneous stick site. A method of delivering a medical electrical lead to a patient's internal jugular vein.
    • 用于使用经皮棒递送神经刺激导致患者颈内静脉的引导递送系统。 该系统包括适于从颈内静脉刺激迷走神经的神经刺激引线。 引线包括近端,远端,插入在近端和远端之间的大致螺旋形的保持结构,并且构造成将引线保持在颈内静脉内,连接到保持结构的电极和插入在 保持结构和近端。 侧端口提供进入从远端延伸到侧端口的内腔。 导丝的尺寸设置成适合于侧端口和内腔,并且减小由保持结构抵抗颈内静脉施加的力,由此通过向引线施加扭矩来允许引线的引导和取向的旋转。 导管具有尺寸适于可滑动地接收医疗电引线并且被配置为提供从经皮粘连部位进入颈内静脉的内腔。 将医用电导线递送到患者的颈内静脉的方法。
