Transvascular neural stimulation device and method for treating hypertension
First Claim
1. An implantable apparatus for treating hypertension, comprising:
- an expandable electrode chronically implantable in a blood vessel and configured to abut an intravascular surface of the blood vessel;
an implantable pulse generator configured to use the electrode in the blood vessel to transvascularly deliver electrical stimulation from the electrode through a wall of the blood vessel to a targeted nerve on or near an extravascular surface of the blood vessel; and
a controller and a memory configured to store instructions operable on by the controller to deliver an electrical stimulation therapy to treat hypertension using electrical stimulation of the nerve from the electrode in the blood vessel.

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.

18. A method for treating hypertension, comprising:
-
chronically implanting an expandable electrode in a blood vessel in a patient who is indicated for a hypertension therapy, including expanding the electrode to abut an intravascular surface of the blood vessel proximate to a targeted nerve on or near an extravascular surface of the blood vessel; and treating hypertension, including using an implantable pulse generator and the electrode in the blood vessel to transvascularly deliver electrical stimulation from the electrode through a wall of the blood vessel to the nerve on or near the extravascular surface of the blood vessel. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
