1. An adapter for connecting a multiple lumen catheter to a corresponding number of single lumen supply tubes, the adapter comprising:
- a one piece molded body having a distal end and a proximal end; and
having a plurality of lumens extending throughout the length of said body, the number of lumens corresponding to the number of lumens in said multiple lumen catheter, said body including;
a first body portion wherein each of said plurality of lumens has a generally circular cross-section and extend for a length sufficient to allow adequate insertion of said supply tubes therein;
a second body portion wherein each of said plurality of lumens has a cross-section generally corresponding to equal sections of a circle and extend for a length sufficient to allow adequate insertion into individual lumens of said multiple lumen catheter; and
a third body portion connecting said first and second body portions wherein each of said plurality of lumens has a cross-section at one end which corresponds with the cross-sections of said plurality of lumens in said first body portion and a cross-section at the other end which corresponds with the cross-sections of said plurality of lumens in said second body portion;
wherein said plurality of lumens are connected along the entire lengths of their respective first and third body portions and are spaced apart along the entire length of their respective second body portions so as to constitute insertion ends for insertion into individual lumens of said multiple lumen catheter, andwherein said third body portion of said adapter further includes a semi-conical direction orienting section associated with each of said plurality of lumens and extending along at least a part of the length of said third body portion.
