Transvascular neural stimulation device
First Claim
1. An implantable apparatus for transvasculary stimulating a vagus nerve trunk in a cervical region from an internal jugular vein (IJV) to provide a therapy to inhibit heart failure remodeling, the apparatus comprising:
- an expandable electrode chronically implantable in the IJV, the expandable electrode configured to abut an intravascular surface of the IJV in the cervical region proximate the vagus nerve trunk;
an electrical lead coupled to the expandable electrode, the electrical lead adapted to be intravascularly fed into the IJV;
an implantable pulse generator coupled to the lead and configured to deliver an electrical stimulation signal to the electrode through the lead, wherein the apparatus is configured to transvascularly stimulate the vagus nerve trunk from the IJV; and
a controller adapted to control the pulse generator to deliver a programmable electrical pulse therapy to inhibit heart failure remodeling, wherein the therapy to inhibit heart failure remodeling includes stimulating to the vagus nerve in the cervical region.

Abstract
This document discusses, among other things, apparatus, systems, and methods for transvascularly stimulation of a nerve or nerve trunk. In an example, an apparatus is configured to transvascularly stimulate a nerve trunk through a blood vessel. The apparatus includes an expandable electrode that is chronically implantable in a blood vessel proximate a nerve trunk. The expandable electrode is configured to abut a predetermined surface area of the vessel wall along a predetermined length of the vessel. An electrical lead is coupled to the expandable electrode. An implantable pulse generator is coupled to the lead and configured to deliver an electrical stimulation signal to the electrode through the lead. In an example method, an electrical signal is delivered from an implanted medical device to an electrode chronically implanted in a blood vessel proximate a nerve trunk to transvascularly deliver neural stimulation from the electrode to the nerve trunk.
