ABSTRACT:
An apparatus for use during examination of the colon of a patient includes an insertion member and a tube member. The insertion member, which occludes the opening into the colon, has first and second channels extending between inner and outer ends. The first channel receives a colonoscope, while the second channel receives the tube member. Seals are provided to prevent air leakage from inside of the colon out through the two channels. The tube member provides a conduit into the colon that is independent of the colonoscope. The tube member has an inside channel for receiving colonoscopic tools. There is an inflatable balloon at the inner end of the tube member, for blunting the tube member inner end. An inflation channel extending betwen the balloon and the tube member outer end allows the balloon to be remotely inflated. With the insertion member in place in the opening, the tube member is inserted into the colon, via the second channel. The tube member provides a conduit for directing tools to a point of interest inside the colon, which tools are used to remove and retrieve tissue samples of the colon walls.
