Allurion Technologies has raised $27 million in the past year as it gets ready for FDA approval of Elipse Therapy, a novel nonsurgical treatment for obesity: a pill that inflates a balloon in your stomach.

Dr. Shantanu Gaur and his classmate, Dr. Samuel Levy, conceived of a pill that, once swallowed, releases a balloon made of thin polymer film with a tube trailing behind it. As soon as it hits your stomach, about 2.5 cups of water mixed with preservative is pumped through the tube into the balloon. The tube is removed through the mouth, the balloon’s inflated and you’re left feeling full. Total elapsed time: 15 minutes.
