ABSTRACT:
A multi-lumen-catheter flow valve system (10) comprises a catheter (14) having three separated lumens (70, 72, 74), each lumen having a separate outlet opening (122a-c) at a distal end portion of the catheter, and a selective-in/all-out valve apparatus (12). The valve apparatus has red, grey and blue input ports (46, 48, 50) and center, first offset and second offset output ports (64, 66, 68), each of the input ports being selectively coupled to a fluid source (16, 18 or 20) and each of the output ports being coupled to a lumen of the blood vessel catheter. The valve apparatus can be adjusted to selectively transmit fluid(s) entering the three input ports to the three output ports without mixing the fluids and to transmit fluids entering a lesser number of input ports than output ports to the three output ports, also without mixing the fluids.
