A gastro-electric stimulation system includes an INS for producing an
electrical stimulation signal, at least one medical electrical lead, and
at least two electrical contacts. The medical electrical lead has a
proximal end and a distal end, the proximal end being connected to the
INS, the distal end being adapted for placement in or near a patient's
stomach or appropriate nerve or nerve portion. The electrodes are
disposed near the distal end of the medical electrical lead, and are
electrically connected through the medical electrical lead to the INS to
receive the electrical stimulation signal and convey such signal to the
selected electrode implant position. The electrical stimulation signal is
provided in an amount and manner adapted to increase the pH of the
gastric acid in the patient's stomach and/or to decrease the amount of
gastric acid produced thereby.
