1. A ligating system, comprising:

  • a ligating apparatus configured to attach to a distal end of a scope and to hold a ligating band thereon;

    an activating cord configured to extend down a working channel of the scope and attach to the ligating apparatus; and

    a line pulling assembly including;

    a central body;

    a first attachment mechanism on the central body, the first attachment mechanism configured to mount about a proximal end of the scope distal to a working channel access port of the scope;

    a second attachment mechanism coupled with the central body and configured to abut an external periphery of the proximal end of the scope proximal to the working channel access port of the scope, wherein the first and second attachment mechanisms are configured to secure the line pulling assembly onto the proximal end of the scope adjacent to the working channel access port of the scope without covering the access port;

    an access channel through the central body and configured to be in communication with the working channel of the scope, the access channel providing an open inlet to the working channel of the scope when the line pulling assembly is attached to the proximal end of the scope; and

    a winding mechanism attached to the central body, wherein the winding mechanism is configured to pull the activating cord proximally such that the ligating band is removed from the ligating apparatus.
