Abstract:
1. A ligating instrument for mounting on an endoscope, the ligating instrument comprising: (a) a ligating band dispenser comprising a support structure and at least one ligating band positioned on the support structure; (b) a pull line extending from the ligating band dispenser and adapted to be pulled for deploying said at least one ligating band off of the support structure; (c) an actuator member adapted to pull the pull line to cause deployment of said at least one ligating band off of the support structure; (d) an elongate member having a lumen, the elongate member extending from the actuator member to the ligating band dispenser, the elongate member being adapted to be positioned outside of the endoscope from the ligating band dispenser to the actuator member; wherein the pull line extends through the 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, wherein actuation of the actuator member draws the pull line in a proximal direction through the elongate member to deploy said at least one 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; and (e) an extendable sleeve positioned on a distal portion of the ligating instrument, wherein the sleeve is adapted 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.
