Splittable multiple catheter assembly

A removable hub ( 100 ) for a catheter ( 170 ) including a lower portion ( 110 ) having a lower proximal end ( 114 ), a lower distal end ( 112 ), and a lower channel ( 116, 118, 120 ) extending between the lower proximal end and the lower distal end. The catheter hub ( 100 ) further includes an upper portion ( 130 ) having an upper proximal end ( 134 ), an upper distal end ( 132 ), and an upper channel ( 136,138,140 ) extending between the upper proximal end and the upper distal end. The catheter hub ( 100 ) further includes a hinge ( 150 ) connecting the lower portion and the upper portion and a lock ( 152 a, 152 b, 156 a, 156 b) for releasably securing the lower portion and the upper portion to each other, distal from the hinge. When the lower portion is releasably secured to the upper portion, the lower channel and the upper channel form a passageway ( 182, 184, 186 ).
