1. A method of treating gastrointestinal reflux disease in a patient, comprising implanting a device, having a plurality of dimensions, wherein the device is implanted such that the device is oriented between 45 degrees and 135 degrees within a standing patient in relation to a ground surface and wherein the device comprises a housing; a stimulator enclosed within the housing; a plurality of electrodes wherein said electrodes are attached to the outer surface of the housing using conductors at least 1 mm in length wherein the electrodes are attached to the housing by insulated conductors; and a controller configured to electrically generate, and transmit, an electrical pulse train to the LES through the plurality of electrodes, wherein the electrical pulse train is defined by a pulse width in a range of 30 μsec to 5 msec, a pulse amplitude in a range of 2 to 15 mAmp, and a pulse frequency in a range of 2 to 80 Hz; and positioning the plurality of electrodes to be at least 1 mm from the patient's main vagal trunk, to be at least 1 mm from the patient's cardiac tissue and to be in electrical communication with the patient's lower esophageal sphincter (LES).
