ABSTRACT:
A multiple-lumen catheter is disclosed that includes a catheter tube having a generally elongate cylindrical body having an axial passageway extending the length thereof. A septum extends across the interior of the body and along the length thereof in order to divide the body into first and second lumens. A bolus extends from a distal end of the body. The bolus has a passage section including an axial passage portion and a radial passage portion. The axial passage portion is in fluid communication with the first and second lumens. The radial passage portion includes a single port through the side of the bolus whereby the first and second lumens are in fluid communication with the port. According to another form of the invention, the radial passage includes a first port and a second port therein.
