A valve for use in a fluid fillable and implantable device in cooperation with a fill tube includes a main body portion having a channel for receiving the fill tube and wherein the main body portion has an unevenly stressed section that includes a selected section of the channel and wherein the unevenly stressed section is stressed so that the selected section of the channel folds back occluding the channel when the fill tube is withdrawn. The valve also includes a gel-filled chamber in which the main body portion is disposed. The main body portion includes a free end that is occluded by the gel once the fill tube has been withdrawn from the fill tube channel.
