  • Patent number: 12017075
    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.

  • Publication number: 20230397831
    Abstract: A wearable probe includes a sensor module and a control module. The sensor module includes a transmission source to transmit signals into the tissue at a source position, and two detectors to detect a result of the signals, the two detectors including a first detector positioned at a first separation distance from the source position and a second detector positioned at a second separation distance from the source position. The control module includes a controller and a battery to power the controller and the sensor module. The control module includes a processor, a memory including instructions, and a communications interface. The instructions cause the processor to control the sensor module to transmit signals into the tissue and detect results of the signals with the at least two detectors, receive the detected results, store the detected results in the memory, and transmit the detected results to a remote device.
