1. A device, comprising:
at least one ligation band;
an elongated hollow member having an open distal end for receiving tissue therein and at least one exterior groove for loading the at least one ligation band thereon;
a band deployment sleeve slidable over an exterior of the elongated hollow member, the band deployment sleeve having a distal portion configured to move from a radially expanded position in which, when the band deployment sleeve slides longitudinally over the elongated hollow member, the distal portion is disengaged from the at least one ligation band, to a radially contracted position in which, when the band deployment sleeve slides longitudinally over the elongated hollow member, the distal portion engages the at least one ligation band; and
a closing sleeve slidable over an exterior of the band deployment sleeve so that moving the closing sleeve distally over the distal portion of the band deployment sleeve constrains the distal portion from the radially expanded position into the radially contracted position and retracting the closing sleeve proximally over the distal portion of the band deployment sleeve releases the distal portion from the radially contracted position into the radially expanded position.
