Abstract
A sensor based gastric stimulator system and method for gastric stimulation of a patient employing an implantable gastric stimulator, which includes an information processor, an electrical stimulator circuit, and telemetry circuitry. The implantable stimulator senses intrinsic, gastric electrical activity (slow waves and/or peristaltic waves) and delivers electrical stimulation to intentionally disrupt or disorganize that 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 stimulator may be programmed to disrupt/disorganize all or a percentage of the intrinsic, normal gastric electrical activity. The programmer (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. The information processor of the implantable gastric stimulator use…
