Claim:
1. A device for treating obesity of a patient having a stomach and a small intestine, the device comprising: an implantable system including an implantable sensor adapted to be implanted in engagement with a tissue of the stomach of the patient so as to sense parameters therefrom and an implantable stimulator configured to be implanted substantially between a mucosal layer and a muscle layer and configured to apply electrical stimulation to the muscle layer of the stomach and delay passage of food or liquid from the stomach to the small intestine so as to create a feeling of satiety for the patient; and circuitry coupled to the sensor and the stimulator, the circuitry comprising a processor configured for determining when material has been ingested into the stomach of the patient in response to the sensed parameters, the circuitry comprising implanted circuitry adapted for use within the patient, external circuitry adapted for use outside the patient, and telemetry adapted for wirelessly transmitting signals between the implanted circuitry and the external circuitry during use; the implanted circuitry comprising an implanted event memory adapted for storing data in response to the parameters sensed by the sensor; the external circuitry comprising an external event memory and an output coupled to the external event memory, the telemetry intermittently sending the signals in response to the data from the implanted event memory for storage of associated data in the external event memory; and the output indicating to the patient or a treating practitioner the determination by the circuitry that material has been ingested so as to delay passage of food or liquid from the stomach to the small intestine and wherein the processor of the circuitry controls a therapy to delay movement of food or liquid through the stomach and into the small intestine for the patient by altering electrical stimulation in response to the signals so that effectiveness of the therapy is enhanced.
