Abstract

Apparatus for dispensing a plurality of ligating bands individually and sequentially. A support, attached to the distal end of an endoscope, carries the plurality of ligating bands at axially spaced positions along an exterior surface. The distal ends of each set of independent displacement filaments each ligating band releasably attach to the distal edge of the dispenser. Each filament loops around the corresponding ligating band and returns past the distal edge of the dispenser and through the endoscope to the proximal end thereof. When a physician pulls a set of filaments proximally, the loop in each filament advances the corresponding ligating band off the distal edge of the dispenser.
