Abstract:
A multilumen catheter assembly having a distal portion, wherein the catheter assembly comprises:a unitary catheter body having a plurality of lumens disposed therein, wherein the entire body has a generally oval cross section, wherein the unitary catheter body includes a longitudinal plane generally bisecting the unitary catheter body; wherein the plurality of lumens comprises: a first lumen disposed within the unitary catheter body on a first side of the longitudinal plane, wherein the first lumen is generally circular in cross section and has a first length; and a second lumen disposed within the unitary catheter body on a second side of the longitudinal plane, opposing the first side of the longitudinal plane, wherein the second lumen is generally circular in cross section and has a second length, different from the first length; wherein the distal portion of the catheter assembly is split along the longitudinal plane such that each of the first and second lumens is capable of free movement independent of the other of the first and second lumens, wherein the catheter assembly further comprises a first extension tube in fluid communication with the first lumen and a second extension tube in fluid communication with the second lumen.
