Claim:
1. A method for using a ligating instrument mounted on an endoscope, comprising: attaching a ligating band dispenser of the ligating instrument to a distal tip of the endoscope, the ligating band dispenser comprising a support structure and at least one ligating band positioned on the support structure; and deploying the ligating band off of the support structure via an actuator member configured to pull a pull line extending from the ligating band dispenser, an elongate member of the ligating instrument extending from the actuator member to the ligating band dispenser, the elongate member configured to be positioned outside of the endoscope from the ligating band dispenser to the actuator member, an extendable sleeve of the ligating instrument positioned on a distal portion of the ligating instrument, the sleeve configured to be extended proximally such that the sleeve is lengthened proximally along the endoscope and secure at least a portion of the elongate member relative to the outside of the endoscope, wherein the pull line extends through a lumen of the elongate member with a proximal end of the pull line connected to the actuator member and a distal end of the pull line connected to the ligating band dispenser, the pull line entering the ligating band dispenser through an aperture from a position radially outside the ligating band dispenser, wherein an actuation of the actuator member draws the pull line in a proximal direction through the elongate member to deploy the ligating band off of the support structure, and wherein the elongate member establishes a fixed length between the ligating band dispenser and the actuator member.
