Abstract:
A hydraulically multiple ligating band dispenser comprising a body whose distal portion is adapted to support the elastic ligating bands. A tissue contacting surface is disposed surrounding and spaced from the distal portion so as to define a chamber. A seal slidably mounted on the distal potion is shaped to seal the chamber, to which a proximally situated fluid inlet is coupled. By these means pressurized fluid applied to the fluid inlet causes the seal to slide in a distal direction along the distal portion in order to urge the ligating bands distally and to dispense them serially.
