Abstract
An implantable electroacupuncture device for treating a medical condition of a patient through application of electroacupuncture stimulation pulses to a target tissue location within the patient includes 1) a housing configured to be implanted beneath a skin surface of the patient, 2) pulse generation circuitry located within the housing and electrically coupled to at least two electrodes, the pulse generation circuitry being adapted to deliver stimulation sessions by way of the at least two electrodes to the target tissue location in accordance with a stimulation regimen, and 3) a primary battery contained within the housing and electrically coupled to the pulse generation circuitry, the primary battery having an internal impedance greater than 5 ohms and a capacity of less than 60 mAh, wherein the primary battery is the only battery that provides power to the pulse generation circuitry.
