An intubation system is provided for use with an endoscope. The intubation system includes a guide apparatus having a track that is adapted to be associated with the endoscope such that bending of the track is substantially decoupled from bending of the endoscope. The intubation system also includes a positioning device having a first coupling member on the distal end and an intubation device having a second coupling member on the proximal end. The intubation device and the positioning device each include a mating member that is adapted to slidingly engage the track external of the endoscope, whereby the first and second coupling members may be releasably attached together.
