An apparatus ( 50 ) is adapted for insertion in a body lumen ( 140 ) having a surgical connection ( 58 ). The apparatus ( 50 ) includes a first conduit ( 80 ) insertable in the lumen ( 140 ) and having a distal end portion spaced distally beyond the surgical connection ( 58 ). The first conduit ( 80 ) directs fluid through the lumen ( 140 ) and isolates the fluid from the surgical connection ( 58 ). The apparatus ( 50 ) also includes a second conduit ( 84 ) insertable in the lumen ( 140 ). The second conduit ( 84 ) has a distal end portion positioned adjacent the surgical connection ( 58 ). The second conduit ( 84 ) is adapted to control the pressure in a space ( 90 ) in which the surgical connection ( 58 ) is exposed. |
