Abstract:
A multilumen catheter assembly comprising:a unitary catheter body having: a proximal end, a distal end; and a generally rounded exterior cross section being disposed between the proximal end and the distal end, wherein the unitary catheter body includes a plurality of lumens disposed therein and a longitudinal plane generally bisecting the unitary catheter body, wherein to plurality of lumens comprises: a first lumen disposed on a first side of to longitudinal plane, wherein the first lumen is generally circular in cross section along its length; and a second lumen disposed on a second side of the longitudinal plane, wherein the second lumen is generally circular in cross section along its length; and first and second distal end tubes, each having generally circular interior cross sections, wherein each of the first and second distal end tubes extends distally from the distal end of the unitary catheter body, wherein each of the first and second distal end tubes comprises a proximal tip fixedly connected to each of the first and second lumens, respectively, and wherein each of the first and second distal end tubes further comprises a distal tip, wherein the first and second distal end tubes are separate from each other at their respective distal tips such that each of the first and second distal tip is capable of free movement independent of the other of the first and second distal tip, wherein the first distal end tube has a first length and the second distal end tube has a second length different from the first length, and wherein the first and second distal end tubes are splittable along the longitudinal plane from each other along at least a splittable portion of the first and second distal end tubes.
