A medical device introduction system and method can include a medical introducer, a separate imaging device, and/or a separate working channel device, each of which may be movable independent of the other. The medical introducer can include a handle and an elongate introducer tube extending from the handle and having a plurality of lumens, and may be inserted into an interior body region of a patient. The separate imaging device may be inserted through the handle and positioned in one of lumens. The separate working channel device can include an elongate working channel tube and a position controller. The working channel tube can include at least one lumen defining a working channel. The position controller can be configured to control positioning of the working channel tube. The working channel device may be removably connected to the handle and positioned in another lumen. Associated with the medical device may be a slider and a rail that stabilizes a medical device and prevents it from turning allowing medical personnel that previously had to hold the medical device to be free to be able to perform other tasks. The medical device may also possess a bent working channel device that provides easier access to orifices or other body parts that are in an orientation that is not straight (i.e., in an orientation that does not require a bend in the working channel device). The medical device may also have sheaths associated with it that causes a bend in the working channel device that also allows easier access to orifices or other body parts that are not straight
