The present disclosure provides an inflatable weight control device that is implanted long-term with an endoscope in obese and bariatric human patients to promote early and prolonged satiety. The device includes a flexible member coupled to a valve body assembly and an elongated durable module residing within the flexible member. The flexible member is selectively inflated to form two bulbs with a central passageway extending through the bulbs and the valve body assembly. Once the bulbs are inflated, the device is retained within the patients pyloric valve to form a gastric outlet obstruction wherein chyme accumulates and then is directed through the central passageway to reach the patients duodenum. Due to its unique configuration, the implanted device reduces gastric outflow which results in early and prolonged satiety when the patient consumes normal-sized meals or food portions, thereby reducing food consumption and increasing the patients weight loss.
