This disclosure describes an implantable medical device that delivers electrical stimulation to a patient in combination with restriction ingestion of food by the patient to treaty obesity. The implantable medical device includes a gastric constriction device, such as a hydraulic or mechanical gastric band having a plurality of electrodes integrally formed thereon. A controller includes a control unit to control the degree of gastric constriction of the gastric constriction device and a pulse generator to control delivery of electrical stimulation to the patient. The control unit and pulse generator are enclosed within a housing implanted within the patient. By enclosing the control unit and pulse generator within a common housing, the trauma experienced by the patient during the implantation procedure may be substantially reduced. Additionally, the cost of the controller may be less than the cost of purchasing a control unit and a pulse generator separately.
