A tiny magnetic bracelet implanted at the base of the throat is helping some people with chronic heartburn who can't get enough relief from medicines. It's a novel way to treat severe acid reflux. That condition plagues millions of Americans and can raise their risk for more serious health problems.
It happens when a weak muscle doesn't close after swallowing as it should. That lets stomach juices splash back into the throat.
The new device is made by a Minnesota company, Torax Medical Inc. The federal Food and Drug Administration approved it last year.
The device is a ring of titanium beads with magnets inside. It's placed around the weak muscle at the base of the esophagus in a half-hour operation.
