摘要：
A variety of passive intragastric implant devices for obesity treatment are disclosed. Such passive devices do not autonomously change shape, but instead react within the stomach to induce satiety. The devices may take up volume within the stomach, thus reducing the intake capacity. Additionally, the devices may contact areas within the stomach, such as the cardia surrounding the esophageal sphincter, to stimulate satiety-inducing nerves. Also, certain devices slow gastric emptying by blocking or otherwise impeding flow through the pyloric sphincter. A number of devices combine two or more of these satiety-inducing features. Methods of implant are disclosed including compressing the devices within a delivery tube and transorally advancing the devices through the esophagus to be deployed within the stomach. Removal of the devices occurs in the reverse.
