A system and method for assembling a catheter device, wherein a septum actuator is positioned within the lumen of a catheter adapter to provide a pathway through a septum component, an introducer needle being inserted through the septum via the septum actuator thereby preventing damage to the septum
A system and method for assembling a catheter device, wherein a septum actuator is positioned within the lumen of a catheter adapter to provide a pathway through a septum component, an introducer needle being inserted through the septum via the septum actuator thereby preventing damage to the septum, the septum actuator thereafter being withdrawn from the septum and positioned within a rearward chamber of the catheter adapter lumen.

1. A method for manufacturing a catheter assembly, the method comprising: providing a catheter adapter having a proximal opening, a distal opening, and a lumen therebetween;swaging a catheter into the distal opening of the catheter adapter, the catheter and the lumen being in fluid communication;insertedly positioning a septum into the lumen, whereby the septum divides the lumen into a forward chamber and a rearward chamber;inserting a septum actuator into the catheter adapter;advancing the septum actuator through the septum thereby providing a pathway between the forward chamber and the rearward chamber, the septum actuator being approximately coaxially centered within the catheter adapter;providing a clamp having a closed position, an opened position, and a middle position, the clamp further having an inner surface for gripping a needle, and an outer surface for selectively contacting an inner surface of the septum actuator;gripping the needle with the inner surface of the clamp by positioning the clamp to the closed position;advancing the needle and the clamp into the proximal opening of the catheter adapter in a distal direction such that the clamp and the needle are approximately coaxially centered within the septum actuator, and such that a tip portion of the needle is positioned in the forward chamber;repositioning the clamp to the opened position such that the inner surface of the clamp releases the needle, and the outer surface of the clamp contacts the inner surface of the septum actuator;withdrawing the clamp and the septum actuator in a proximal direction such that the septum actuator is withdrawn from the septum and is entirely positioned in the rearward chamber;repositioning the clamp to the middle position such that neither the inner surface nor the outer surface of the clamp contact the needle nor the septum actuator, respectively;withdrawing the clamp from the rearward chamber; andremoving the clamp from the catheter adapter such that at least a portion of the needle remains within the forward chamber. 2. The method of claim 1, wherein following the step of withdrawing the clamp from the rearward chamber, the method further includes the steps of: repositioning the clamp to the closed position so as to grip a proximal portion of the needle;advancing the clamp and the needle in the distal direction whereby the tip portion of the needle is advanced through the forward chamber and into the catheter;repositioning the clamp to the middle position; andwithdrawing the clamp in the proximal direction such that the clamp is removed from the rearward chamber. 3. The method of claim 1, further comprising coating the tip portion of the needle with a lubricant. 4. The method of claim 3, further comprising gripping the needle at a position proximate to the lubricant. 5. The method of claim 1, wherein an outer diameter of the clamp coaxially centers the needle and the clamp within the septum actuator. 6. The method of claim 5, wherein the outer diameter is less than an inner diameter of the catheter adapter and greater than an inner diameter of the septum actuator. 7. The method of claim 1, wherein the outer surface of the clamp is outwardly tapered in the proximal direction. 8. The method of claim 1, further comprising coupling the clamp to an automation system, wherein the automation system controls the positions of the clamp relative to the needle and the catheter assembly. 9. A method for insertedly positioning a needle in a catheter assembly, the catheter assembly comprising a catheter coupled to a catheter adapter, the catheter assembly further comprising a septum disposed within a lumen of the catheter adapter, the septum dividing the lumen into a forward chamber and a rearward chamber, and a septum actuator disposed within the septum so as to provide a pathway between the forward and rearward chambers, the method comprising: providing a clamping device having a closed position, an opened position, and a middle position, the clamping device further having an inner surface for selectively retaining the needle, and an outer surface for selectively contacting an inner surface of the septum actuator;securing the needle in the inner surface of the clamping device by repositioning the clamping device to the closed position;coaxially inserting the needle and the clamping device into the rearward chamber and the septum actuator such that a tip portion of the needle passes through the septum via the pathway;repositioning the clamping device to the opened position such that the inner surface releases the needle and the outer surface contact the inner surface of the septum actuator;withdrawing the clamping device and the septum actuator in a proximal direction such that the septum actuator is removed from the septum and entirely positioned within the rearward chamber;repositioning the clamping device to the middle position such that neither the inner surface nor the outer surface of the clamp contact the needle nor the septum actuator, respectively;withdrawing the clamping device from the rearward chamber; andremoving the clamping device from the catheter assembly, such that a portion of the needle remains within the forward chamber. 10. The method of claim 9, wherein following the step of withdrawing the clamping device from the rearward chamber, the method further includes the steps of: repositioning the clamping device to the closed position so as to grip a proximal portion of the needle;advancing the clamping device and the needle in the distal direction whereby the tip portion of the needle is advanced through the forward chamber and into the catheter;repositioning the clamping device to the middle position; andwithdrawing the clamping device in the proximal direction such that the clamping device is removed from the rearward chamber. 11. The method of claim 9, further comprising coating the tip portion of the needle with a lubricant. 12. The method of claim 11, further comprising gripping needle with the clamping device at a position proximate to the lubricant. 13. The method of claim 9, wherein the outer surface of the clamping device is outwardly tapered in the proximal direction. 14. The method of claim 9, further comprising coupling the clamping device to an automation system, wherein the automation system controls the positions of the clamping device relative to the needle and the catheter assembly.
