System and method for transvascularly stimulating contents of the carotid sheath
First Claim
1. A method for intravascularly stimulating contents of the carotid sheath, comprising:
- intravascularly advancing an energy-delivery element into an internal jugular vein;
retaining the energy delivery element in a portion of the internal jugular vein contained within a carotid sheath; and
energizing the energy delivery implant to transvenously direct energy to target contents of the carotid sheath external to the internal jugular vein, said target contents comprising a first target and a second target, the first target selected from the group of targets consisting of a vagus nerve and a vagus nerve branch, the second target selected from the group of targets consisting of a carotid sinus nerve, a carotid sinus nerve branch, and a carotid artery.

Abstract
Methods and systems are disclosed for stimulating contents of the carotid sheath using an intravascular pulse generator and lead. The lead carries an energy delivery device such as an electrode, which is anchor within the portion of the internal jugular vein that is disposed within the carotid sheath. The energy delivery device is energized to transvenously direct energy to target contents of the carotid sheath external to the internal jugular vein. Such target contents may include nervous system elements associated with the carotid sinus baroreceptors, the carotid sinus nerve and associated nerve branches, and or the vagus nerve and associated nerve branches. The system may be used to control blood pressure and/or to lower heart rate and may be suitable for treatment of hypertension, heart failure, or other conditions.

13. An intravascular system for stimulation of contents of a carotid sheath, the system comprising:
-
a pulse generator positionable within a blood vessel; a lead coupled to the pulse generator; an anchor adapted to anchor the lead in a portion of an internal jugular vein disposed in a carotid sheath; a plurality of electrodes disposed on the lead, the electrodes including a first array and a second array, wherein the first and second arrays are positioned such that when the first array is positioned in the internal jugular vein to direct stimulation energy transvascularly to a vagus nerve in the carotid sheath, the second array is positioned to direct stimulation energy transvascularly towards a carotid artery or carotid sinus nerve within the carotid sheath. - View Dependent Claims (14, 15)
