Abstract:
1. A system for gastric stimulation of a patient comprising: a plurality of sensing electrodes for sensing intrinsic gastric activity from a stomach wall of a patient; an implantable gastric stimulator coupled to the plurality of sensing electrodes, the implantable gastric stimulator configured to receive the sensed intrinsic gastric activity and perform an analysis of the sensed intrinsic gastric activity to classify the activity as normal or abnormal, and determine whether to create an electrical stimulation based at least in part upon the classification of the sensed intrinsic gastric activity as normal or abnormal, wherein the implantable gastric stimulator delivers the electrical stimulation when the sensed intrinsic gastric activity is classified as normal; a plurality of stimulation electrodes configured to convey the electrical stimulation from the implantable gastric stimulator to the stomach wall of the patient, wherein the plurality of stimulation electrodes defines a plurality of stimulation vectors, wherein: the electrical stimulation is configured to disrupt normal gastric activity of the stomach, and the implantable gastric stimulator is configured to switch between any of the plurality of stimulation vectors depending upon the sensed intrinsic gastric activity.
