Stomach Sucker: How Does New Weight-Loss Device Work?

The Food and Drug Administration recently approved a weight-loss device that may sound like something out of a science-fiction movie: a small tube inserted into the stomach allows patients to drain a portion of their gut's contents before the body absorbs those calories. The device, called AspireAssist, was approved by the FDA after a year-long clinical trial on 171 people, 111 of whom underwent a procedure to place the device. But not all weight-loss experts think the device is a game-changer.
