Implantable Electroacupuncture Device and Method for Treating Dyslipidemia (US 8,942,816 B2)


An Implantable ElectroAcupuncture Device (IEAD) treats dyslipidemia conditions of a patient through application of stimulation pulses applied at acupoint ST40, or its underlying nerves saphenous and peroneal. The IEAD comprises an implantable, coin-sized, self-contained, leadless electroacupuncture device having at least two electrodes attached to an outside surface of its housing. The device generates stimulation pulses in accordance with a specified stimulation regimen. Power management circuitry within the device allows a primary battery, having a high internal impedance, to be used to power the device. The stimulation regimen generates stimulation pulses during a stimulation session of duration T3 minutes applied every T4 minutes. The duty cycle, or ratio T3/T4, is very low, no greater than 0.05. The low duty cycle and careful power management allow the IEAD to perform its intended function for several years.
