Overmolded septum for catheter hub

1. A method of constructing a catheter assembly, comprising:

molding a catheter hub having a distal end, a proximal end, and an internal wall defining an internal fluid passageway therebetween, the internal 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 the proximal end of the catheter hub with a first mold core shut off pin and plugging a portion of the internal fluid passageway in proximity to the proximal end of the catheter tube with a second mold core shut off pin; and

injection molding a septum in between the first mold core shut off pin and the second mold core shut off pin through the injection mold window.

2. The method of claim 1 , further comprising defining a slit and/or pierce in the septum.

3. The method of claim 1 , further comprising adding a proximal hub component to the proximal end of the catheter hub to compress to the septum.

4. The method of claim 1 , further comprising overmolding material around at least a portion of the catheter hub concurrently with the molding of the septum.

5. The method of claim 4 , wherein the overmolded material includes wings.

6. The method of claim 1 , wherein the internal wall of the catheter hub further defines a side port in communication with the internal fluid passageway.

7. The method of claim 6 , further comprising operably coupling a length of tubing to the side port.

8. The method of claim 1 , wherein the septum extends at least partially through the injection mold window, thereby aiding in the retention of the septum within the internal fluid passageway.

9. A method of constructing a catheter assembly, comprising:

loading a catheter tube having a proximal end and a distal end into a catheter assembly mold;

overmolding a catheter hub around at least the proximal end of the catheter tube, the catheter hub having a distal end, a proximal end, and an internal wall defining an internal fluid passageway therebetween, the internal wall defining an injection mold window located between the distal end and the proximal end;

plugging at least the 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, the septum defining a beveled distal end configured to reduce a pocket within the internal fluid passageway to inhibit stagnation of fluid flowing therethrough.

10. The method of claim 9 , further comprising defining a slit and/or pierce in the septum.

11. The method of claim 9 , further comprising adding a proximal hub component to the proximal end of the catheter hub to axially compress to the septum.

12. The method of claim 9 , further comprising overmolding wings around at least a portion of the catheter hub concurrently with the molding of the septum.

13. The method of claim 9 , wherein the internal wall of the catheter hub further defines a side port in communication with the internal fluid passageway.

14. The method of claim 13 , further comprising operably coupling a length of tubing to the side port.

15. The method of claim 9 , wherein the septum extends at least partially through the injection mold window, thereby aiding in the retention of the septum within the internal fluid passageway.
