Abstract: A ureteroscope system includes a handle; an elongated shaft extends from the handle to a distal end and includes a working channel which is opened at the distal end; an external member extends from a proximal end to a distal end and is coupled to the shaft, the member includes a hub and a tube defining a first external channel; and a coupling mechanism defines first and second tubes and is coupled the distal end of the member to the distal end of the shaft. The first tube defines a first lumen and the second tube defines a second lumen which is sized and shaped to receive a distal end of the member. A proximal portion of the first tube is sized and shaped to be inserted into a distal portion of the shaft such that the first lumen is opened to the working channel.
