ABSTRACT:
A device for directing a wire guide into a bodily passageway such as a branch of the biliary tree or other difficult to access bodily passageway. The device includes a member, such as an inflatable balloon or a self-expanding basket, for obstructing a first passage. Once the balloon is inflated, or the basket expanded, the wire guide can be reliably directed or deflected into a preferred adjacent passageway in order to cannulate the preferred adjacent passageway. A procedure for cannulating a preferred passageway by obstructing a passageway in the natural flow-path of a wire guide is also provided.
