A multiple catheter assembly ( 100 ) including a first catheter ( 110 ) having a first proximal end region ( 112 ), a first distal end region ( 114 ) terminating in a first distal tip ( 116 ), and an outer surface ( 120 ) defining at least a first lumen ( 122 ) extending longitudinally therethrough between a first distal and a first proximal opening. The assembly ( 100 ) also includes a second catheter ( 130 ) having a second proximal end region ( 132 ), a second distal end region ( 134 ) terminating in a second distal tip ( 136 ), and a second outer surface ( 140 ) defining at least a second lumen ( 142 ) extending longitudinally therethrough between a second distal and a second proximal opening. The first ( 122 ) and second ( 142 ) lumens are independent from each other for facilitating simultaneous flow in opposite directions. The outer surfaces ( 120,140 ) of the first and second catheters are releasably joined for allowing the first and second distal tips ( 116,136 ) and first and second proximal end regions ( 112,132 ) to be at least partially longitudinally split from each other. A method of inserting the catheter assembly ( 100 ) is also provided that includes a method of attaching a hub to the catheter assembly. |
