Abstract
A ligating band is formed so as to have a pre-stress compression along its inner periphery and a pre-stress tension along its outer periphery at a free state, wherein all the material of the band is at a substantially equal tension when the band is subject to full circumferential expansion. In a free state, the inner periphery can buckle, at least partially filling an inner perimeter defined by the inner periphery with a plurality of material folds.
