  • Publication number: 20190351235
    Abstract: A system for stimulating a sympathetic chain includes an electrode assembly that is configured to attach to a bone in proximity to a targeted portion of the sympathetic chain. The electrode assembly includes a cathode and an anode. The system also includes a power supply connected to the electrode assembly and configured to deliver power to the electrode assembly. The electrode assembly generates an electrical field between the cathode and the anode when power is delivered to the electrode assembly. The electrical field reaches the targeted portion of the sympathetic chain to provide electrical stimulation to the targeted portion of the sympathetic chain.
