Patent ID: 8903509

Claim:
A system for stimulating a target region of a vagus nerve from a location within an internal jugular vein, the system comprising: a medical lead comprising a lead body extending from a proximal end to a distal end, a conductor extending within the lead body from the proximal end in a direction towards the distal end, and at least one electrode located on the lead body and operatively coupled to the conductor, the electrode configured to transvascularly deliver an electrical stimuli to the target region of the vagus nerve from a location within the internal jugular vein; and an insulating element including an insulating sheath formed from a flexible sheet of electrically insulative material, wherein the insulating sheath is configured to be implanted within the internal jugular vein and disposed about the lead and to insulate nerve structures proximate the vagus nerve from stimulation, wherein the insulating element further comprises a stent-like fixation member configured to expand from a collapsed delivery configuration to an expanded configuration, wherein in the expanded configuration, the stent-like fixation member is configured to secure the insulating sheath to an inner wail of the internal jugular vein, and wherein the insulating sheath includes at least one window configured to be located between the lead and the target region of the vagus nerve through. which the electrical stimuli can be delivered to the target region of the vagus nerve.
