ABSTRACT:
A ligating band dispenser for dispensing a plurality of ligating bands individually during a sequence of operations for a ligating instrument. Interfitted housing and piston segments support a plurality of ligating bands at axially spaced locations. Retraction of the piston segment dispenses one ligating band and shifts the remaining ligating bands distally and axially. After retraction, the piston is biased forward so a next retraction dispenses another ligating band. A sclerotherapy needle mounts in a sheath that connects to the piston segment. A physician retracts the sheath to retract the piston. In addition the physician can advance the sclerotherapy needle through the sheath to administer a sclerotherapy agent as an alternative to ligating a lesion.
