Abstract

A probe intended to be introduced within a living body, of the type comprising an elongated structure adapted to be introduced in a canal in said living body conveying a fluid, and presenting, at its end intended to be introduced in the canal, a single bag element connected to said structure, surrounding the latter and radially deformable so as to be able to come into contact with the inner wall of said canal. According to the invention, this probe is characterized in that it comprises at least one conduit (8), connected to said structure (3), extending at least substantially parallel to said structure (3) and outside the latter, over a distance corresponding substantially to the longitudinal dimension of said bag element (5), so as to be able to place in communication those parts (2a, 2b) of said canal (2) immediately upstream and downstream of said bag element (5) in order thus to maintain a minimum circulation of fluid in said canal (2).
