Abstract:
An instrument for selectively transferring a fluid and for dispensing ligature bands for band ligation, said instrument comprising:A. a ligature band dispenser adapted for coupling with a distal end of an endoscope and including first and second coaxially located segments for supporting a ligature band thereon and one of said segments being moveable between first and second positions relative to the other of said segments thereby to dispense the ligature band from the distal end of said instrument,B. an elongated sheath adapted for extension from the distal end of said instrument to a location exteriorly of said endoscope at a proximal end thereof through an endoscope working lumen, said sheath being adapted for attachment to said one segment and being slidable in the working lumen to operate said ligature band dispenser, andC. an elongated catheter extending through said elongated sheath to beyond the proximal and distal ends thereof and being slidable in said elongated sheath for defining a fluid transfer passage between the proximal and distal ends of said elongated catheter.
