Splittable multilumen catheter assembly
First Claim
1. A multilumen catheter assembly comprising:
- a unitary catheter body having;
a proximal end;
a distal end;
a plurality of lumens disposed between the proximal end and the distal end; and
a longitudinal plane generally bisecting the unitary catheter body, wherein the plurality of lumens comprises;
a first lumen disposed on a first side of the longitudinal plane, wherein the first lumen includes a first distal end tube, wherein the first distal end tube includes at least one of a tongue and a groove disposed proximate to the longitudinal plane; and
a second lumen disposed on a second side of the longitudinal plane, wherein the second lumen includes a second distal end tube, wherein the second distal end tube includes at least the other of the tongue and the groove disposed proximate to the longitudinal plane;
wherein each of the at least one tongue is disposable across the longitudinal plane into a respective at least one groove and wherein the first and second distal end tubes are splittable along the longitudinal plane from each other by removing at least a portion of each of the at least one tongue from at least a portion of each of the at least one groove.

Abstract
A multilumen catheter assembly is provided, which includes a unitary portion and at least two distal end tubes extending distally from the unitary portion. The unitary portion includes an exterior having a generally round or oval shape in cross section and includes at least two distal end tubes of generally circular (or other) cross sectional shape extending longitudinally therethrough. The catheter assembly may be made by extruding a unitary tube having internal longitudinally extending lumens (of circular or other shape), then splitting the tube on its distal end portion to form distal end tubes. The tubes are then ground and polished, the finished tubes retaining in combination the generally oval cross sectional shape of the unitary extrusion, or the finished tubes can each be finished to a circular, or other, cross sectional shape; or the finished tubes could include a combination of cross sectional shapes over its longitudinal length.
