A bariatric device and method of causing at least partial satiety in a recipient that either has or is presently undergoing a procedure that alters the anatomy of the recipient includes deploying a bariatric device to the recipient having an altered anatomy. The bariatric device includes a cardiac member having a cardiac surface that is configured to generally conform to the shape and size of a portion of the cardiac region of the stomach of the recipient. The cardiac member stimulates receptors with the cardiac surface in order to influence a neurohormonal mechanism in the recipient sufficient to cause at least partial satiety by augmenting fullness caused by food and simulating fullness in the absence of food.
