摘要:
A lead delivery system for delivering a neurostimulation lead to a patients 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 patients internal jugular vein.
