Method for treating cardiovascular disease using implantable electroacupuncture device
First Claim
1. A method of treating heart failure, coronary artery disease, myocardial ischemia or angina in a patient using a leadless implantable electroacupuncture device (IEAD) that includes a central electrode of a first polarity and centrally located on an outside surface of a housing of the leadless IEAD and an annular electrode of a second polarity and that is spaced apart from and surrounds the central electrode on the outside surface of the housing of the leadless IEAD, said method comprising:
- (a) implanting the leadless IEAD below a skin surface of the patient at or near an acupoint selected from a group of acupoints that includes;
PC6, ST36, BL14, EX-HN1, HT7, HT5, LI11, LU2 and LU7, and(b) enabling the leadless IEAD to apply stimulation sessions at the acupoint by way of the central electrode and the annular electrode in accordance with a stimulation regimen, wherein the stimulation sessions each comprise a plurality of stimulation pulses, wherein the stimulation regimen defines the stimulation sessions to each have a duration of T3 minutes and a rate of occurrence of once every T4 minutes, wherein a ratio of T3 to T4 is no greater than 0.05, and wherein T3 is at least 10 minutes and no greater than 60 minutes.

Abstract
An Implantable ElectroAcupuncture Device (IEAD) treats cardiovascular disease through application of stimulation pulses applied at at least one of acupoints EX-HN1, BL14, HT7, HT5, PC6, ST36, LI11, LU7, and LU2. 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.
