The delay is to allow for healing. They put a device on the right side of my chest and ran a wire up into my jaw next to the nerve that controls the tongue. The incisions need to heal and scar tissue to form to keep the wire in place.
I had a stroke three years ago and lost a little more than 30 lbs. I use a Bipap machine and my pressure 19/15 keeps going up. Had to do something.
