Abstract
A method of constructing a catheter assembly having an integrated septum. The method comprising molding a catheter hub having a distal end, a proximal end, and an internal wall defining an internal fluid passageway therebetween, the internal fluid wall defining an injection mold window located between the distal end and the proximal end; seating a catheter tube within the internal fluid passageway of the catheter hub, such that a proximal end of the catheter tube resides within the internal fluid passageway of the catheter hub, and a distal end of the catheter tube extends distally from the distal end of the catheter hub; plugging at least a proximal end of the catheter hub with a mold core shut off pin; and injection molding a septum in at least a portion of the internal fluid passageway between the mold core shut off pin and the proximal end of the catheter tube through the injection mold window.
