Abstract
A catheter may include a multiple lumen catheter tube, a hub attached to the catheter tube, and a first extension leg and a second extension leg attached to the hub. The multiple lumen catheter tube may include a longitudinal axis, an end, a first lumen, and a second lumen. The first lumen and the second lumen extend through the catheter tube along the longitudinal axis and each having an opening. The end of the catheter tube and the openings of the lumen may be disposed within the hub so that the opening of the first lumen is axially spaced with the end of the catheter tube. The first extension leg may be coupled to the first lumen and the second extension leg may be coupled to the second lumen for the separate delivery of fluids to the lumens.
