Abstract: The present disclosure relates generally to ligators, actuation devices, and methods for deploying ligation bands around a portion of tissue, utilizing an endoscope for suction, visualization, and support. In some embodiments, a ligator may include an elongate member having a lumen, and a ligating band dispenser extending from a distal end of the elongate member. The ligating band dispenser may include a cap and at least one ligating band on the cap. The ligator may further include an actuation device extending around the elongate member, wherein the actuation device includes a body, and a bobbin coupled to the body by support arms. A suture may be coupled between the bobbin and the at least one ligating band, wherein rotation of the bobbin draws the suture towards a proximal end of the elongate member to deploy the at least one ligating band from the cap.
