TRANSVASCULAR RESHAPING LEAD SYSTEM
First Claim
1. An electrical lead, comprising:
- a proximal portion configured to connect to an implantable medical device;
an expandable portion configured to be chronically implanted in a blood vessel proximate a nerve trunk and configured to be expanded to asymmetrically expand the blood vessel against the nerve trunk to stabilize the lead in a fixed position within the vessel; and
a sensor along the expandable portion of the lead.

Abstract
A system for selective activation of a nerve trunk using a transvascular reshaping lead is provided. One aspect of this disclosure relates to a system for spreading nerve bundles in a nerve trunk. The system includes a lead adapted to be chronically implanted in a blood vessel proximate a nerve trunk, and having an expandable portion adapted to be expanded to reshape the blood vessel to an elongated shape and to reshape the nerve trunk into an elongated shape to spread nerve bundles of the nerve trunk. The system also includes a plurality of electrodes and an implantable device coupled to the lead, where an electrical signal is delivered from the implanted medical device to one of the plurality of electrodes to transvascularly deliver neural stimulation from the electrode to at least one of the nerve bundles of the nerve trunk. Other aspects and embodiments are provided herein.

6. A method, comprising:
-
asymmetrically expanding an expandable portion of an electrical lead, adapted to be chronically implanted in a blood vessel proximate a nerve trunk, to stabilize the lead in a fixed position within the vessel; reshaping the blood vessel by further asymmetrically expanding the expandable portion, to expand the blood vessel against the nerve trunk to reshape the nerve trunk to spread nerve bundles of the nerve trunk; and delivering an electrical signal from an implanted medical device to an electrode positioned at the expandable portion of the lead to transvascularly deliver neural stimulation from the electrode to at least one of the nerve bundles of the nerve trunk. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A method, comprising:
-
placing a transvascular reshaping lead within a blood vessel to position an electrode on the lead proximate a neural target, the neural target including a nerve bundle within a nerve trunk; spreading nerve bundles within the nerve trunk by expanding the transvascular reshaping lead to asymmetrically expand the blood vessel against the nerve trunk; delivering an electrical signal from an implanted medical device attached to the lead to the electrode to transvascularly deliver neural stimulation from the electrode to the neural target. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
