Abstract
A ligating band dispenser includes a cylindrical inner sleeve and at least a partially encompassing balloon, where the inner sleeve supports one or more expanded ligating bands external to the balloon. This ligating band dispenser allows the introduction of a pressurized fluid between the inner sleeve and the balloon, proximal to a distal-most, stored ligating band, to effect the distal displacement and dispensing of one or more stored ligating bands.
