The present disclosure pertains to medical devices. More particularly, the present disclosure pertains to tissue retraction devices and related delivery systems and methods.

Devices and methods for tissue retraction

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.
