1. A venous catheter assembly, comprising:
a hub including opposing suture wings;
an extension leg coupled to the hub; and
an elongate catheter tube designed for insertion into a blood vessel of a patient, the elongate catheter tube coupled to the hub, the elongate catheter tube defining an outer wall circumscribing a plurality of lumens, the plurality of lumens comprising:
at least one fluid-carrying lumen within the outer wall extending between a proximal end and a distal end of the elongate catheter tube, the at least one fluid-carrying lumen in fluid communication with the extension leg and an opening in the outer wall at the distal end of the elongate catheter tube; and
at least one terminating lumen within the outer wall extending to a closed termination point within the outer wall, the closed termination point positioned in a proximal end of a reduced diameter portion of the elongate catheter tube intermediately between the proximal end and the distal end of the elongate catheter tube, wherein a diameter of the elongate catheter tube in the reduced diameter portion of the elongate catheter tube is reduced in size distal to the closed termination point for a remaining distal length of the elongate catheter tube due to loss of the at least one terminating lumen.
