摘要

A guide system for accommodating an endoscopic tool. The guide system comprises a flexible inner sheath and a handle coupled to the inner sheath adjacent a proximal end of the inner sheath. The inner sheath includes a plurality of working channels. The working channels are bundled over a common portion of their respective lengths, and the working channels collectively define a substantially honeycombed cross-sectional area.
