DIRECT DELIVERY SYSTEM FOR TRANSVASCULAR LEAD
First Claim
1. A lead delivery system for delivering a neurostimulation lead to a patient'"'"'s internal jugular vein using a percutaneous stick, the system comprising:
- a neurostimulation lead adapted to stimulate a vagus nerve from the internal jugular vein, the lead including 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 providing access to a lumen extending from the distal end to the side port;
a guidewire 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; and
a catheter having 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.

Abstract
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.

11. A lead delivery system for delivering a neurostimulation lead to a patient'"'"'s internal jugular vein using a percutaneous stick, the system comprising:
-
a neurostimulation lead adapted to stimulate a vagus nerve from the internal jugular vein, the lead including a proximal end, a distal end, a retaining structure configured to retain the lead in the internal jugular vein interposed between the proximal and distal ends, and a side port interposed between the retaining structure and the proximal end, the side port providing access to a lumen extending from the distal end to the side port; a guidewire sized to fit within the side port and lumen and reduce a force exerted by the retaining structure against a surface external to the retaining structure, thereby facilitating advancement and orientation of the lead; and a catheter having 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. - View Dependent Claims (12, 13, 14)

15. A method of directly delivering a neurostimulation lead to a patient'"'"'s internal jugular vein, the method comprising:
-
inserting a catheter into the internal jugular vein using a percutaneous stick; inserting a guidewire into a side port and through a lumen of a neurostimulation lead, the neurostimulation lead including a proximal end, a distal end, a retaining structure interposed between the proximal and distal ends, and an electrode coupled to the retaining structure, wherein the side port is interposed between the retaining structure and the proximal end and the lumen extends from the distal end to the side port; advancing a portion of the neurostimulation lead through the catheter and orienting the lead to a desired position in the internal jugular vein; and removing the catheter and the guidewire. - View Dependent Claims (16, 17, 18, 19, 20)
