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 heart failure therapy, 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 implantable pulse generator configured to use the electrode to transvascularly stimulate the vagus nerve trunk from the IJV;
a controller to operate on programmed instructions for delivering the heart failure therapy using the pulse generator and the electrode, wherein the heart failure therapy includes transvascularly stimulating 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.

14. A system for transvasculary stimulating a vagus nerve trunk in a cervical region from an internal jugular vein (IJV) in a cervical region to provide a heart failure therapy, the system comprising:
-
an expandable electrode implantable in the IJV within the cervical region proximate the vagus nerve trunk; a lead assembly coupled to the expandable electrode, the lead assembly including an electrical lead adapted to be intravascularly fed into the IJV; and an implantable device coupled to the lead assembly, the implantable device including a controller circuit to communicate with a neural stimulator, wherein the implantable device is programmed with instructions used by the controller to implement the heart failure therapy, wherein the programmed heart failure therapy includes instructions used by the controller to control the neural stimulator to transvascularly stimulate the vagus nerve in the cervical region using the lead and the electrode. - View Dependent Claims (15, 16, 17, 18)
