Abstract
Abstract A ligating band dispenser for dispensing a plurality of ligating bands individually during a sequence of operations for a ligating instrument. First and second tubular segments define a dispenser that supports a plurality of ligating bands at axially spaced locations thereon. Axially displacement of one of the segments relative to the other segment dispenses one ligating band and shifts the remaining ligating bands distally and axially for subsequent dispensing.
