Banding

Banding is a medical procedure that uses strong elastic bands to constrict the flow of blood to affected tissues, resulting in the eventual death of the tissue.  It is most often used to treat varices of the esophagus and hemorrhoids.
Gastric banding is a procedure used to restrict the size of the stomach to aid weight loss.  This technique can also be used to restrict the function of other organs without destroying them.
