Researchers at the University of Colorado Anschutz Medical Campus are looking for 30 to 40 volunteers to take part in a new clinical trial.
They're testing the world's first biodegradable balloon you can swallow to lose weight.
It's a less invasive alternative to gastric bypass surgery.
Associate professor of gastroenterology at the CU School of Medicine Dr. Shelby Sullivan is leading the trial in Colorado.
“We’re going to be testing the Elipse Balloon, which is a balloon that is delivered in a capsule,” Dr. Sullivan said. “So, you swallow it. And after four months, it opens up, deflates and passes out on its own.”
