Abstract

A sensor based gastric stimulator system and method for gastric stimulation of a patient employing an implantable gastric stimulator ('SINGLE CHAMBER/SWITCHABLE ELECTRODE IGS'), which includes an information processor ('MICROPROCESSOR'), an electrical stimulator circuit ('STIMULATION CIRCUIT'), and telemetry circuitry ('TELEMETRY TRANSCEIVER'). The implantable stimulator senses gastric electrical activity (slow waves and/or peristaltic waves) and delivers electrical stimulation to intentionally disrupt or disorganize a programmed percentage of the normal gastric activity. The stimulation is triggered by (tracks) normal gastric electrical activity and can be delivered with a spatial offset to anticipate the propagating gastric electrical activity or may be delayed temporally to anticipate the next propagating slow or peristaltic wave. The programmer (not shown - via radio frequency data link) may non-invasively program stimulation parameters and intervals. The stimulator may provide stimulation to one or a plurality of stimulation sites and may incorporate one or a plurality of independently programmable sensing and/or stimulation channels (see 'ELECTRODE SWITCHING CIRCUIT' and 'OUTPUT/INPUT ELECTRODES'). The information processor of the implantable gastric stimulator uses the gastric stimulation information from the non-electrode sensor for determining periods or windows of susceptibility for application of the electrical stimulation signals to the patient's stomach wall.
