Came across this new procedure
It's called the linx system. It's still in clinical trials so I guess we wouldn't see it for quite a while...if it's even approved for use. Sounds kinda interesting, though I don't know that I'd want magnets inside me. They put a "bracelet" of magnetic beads around the LES using a laparoscopic procedure. It supposedly lets the food pass through to the stomach, but keeps the LES closed otherwise, so nothing refluxes. And it's supposed to be reversible.
