a septum disposed within and selectively sealing the inner lumen; a septum activator disposed within the inner lumen at a location proximal to the septum and having a proximal opening, the proximal opening of the septum activator having an inner diameter less than the inner diameter of the catheter adapter, the septum activator being configured to advance distally through a slit in the septum; and an activator attachment comprising: a proximal end having a proximal opening; a connector portion comprising a set of threads; a probe member having an outer diameter less than the inner diameter of the proximal opening of the catheter adapter and greater than the inner diameter of proximal opening of the septum activator; and an extension member that extends from a distal end of the probe member, wherein an unrestricted lumen extends from the proximal opening of the activator attachment through the probe member and the extension member, the extension member having an outer diameter less than the inner diameter of the proximal opening of the septum activator, wherein the distal end of the probe member forms a distal-facing ridge that extends radially outward from the extension member, wherein in response to the activator attachment being inserted into the proximal opening of the catheter adapter a first amount, the probe member inserts into the proximal opening of the catheter adapter, the distal-facing ridge contacts a proximal end of the septum activator, the extension member inserts into the proximal opening of the septum activator, the unrestricted lumen is in fluid communication with the inner lumen of the catheter adapter, and the septum remains closed, wherein in response to the connector portion being threaded to the proximal end of the catheter adapter such that the activator attachment is inserted into the proximal opening of the catheter adapter a second amount, the distal-facing ridge forces the septum activator distally through the septum, wherein when the extension member inserts into the proximal opening of the septum activator, a distal end of the extension member is disposed within the inner lumen of the catheter adapter. ### Claim 2 (depends on 1) The catheter assembly system of claim 1, wherein the catheter adapter forms a female luer fitting. ### Claim 3 (depends on 2) The catheter assembly system of claim 2, wherein the female luer fitting is a luer lock fitting. ### Claim 4 (depends on 2) The catheter assembly system of claim 2, wherein the female luer fittings is a luer slip fitting. ### Claim 5 (depends on 1) The catheter assembly system of claim 1, wherein an outer surface of a proximal portion of the activator attachment includes a channel portion. ### Claim 6 (depends on 5) The catheter assembly system of claim 5, wherein the channel portion includes one or more grip portions. ### Claim 7 (depends on 1) The catheter assembly system of claim 1, wherein the connector portion of the activator attachment includes a luer collar that extends around the probe member. ### Claim 8 (depends on 7) The activator attachment of claim 7, wherein the luer collar is a luer lock collar or a luer slip collar. ### Claim 9 (depends on 1) The catheter assembly system of claim 1, wherein a diameter of the unrestricted lumen increases from a distal opening of the activator attachment to a proximal opening of the activator attachment. ### Claim 10 (depends on 1) The catheter assembly system of claim 1, wherein the probe member forms a male luer taper. ### Claim 11 (depends on 1) The catheter assembly system of claim 1, wherein a proximal end of the catheter adapter includes a flange and the connector portion includes a collar that extends around the flange to couple the activator attachment to the catheter adapter. ### Claim 12 (depends on 1) The catheter assembly system of claim 1, wherein a sidewall of the septum activator includes one or more openings, and when the connector portion is threaded to the proximal end of the catheter adapter such that the activator attachment is inserted into the proximal opening of the catheter adapter the second amount, the extension member at least partially covers the one or more openings. ### Claim 13 (depends on 1) The catheter assembly system of claim 1, further comprising a catheter coupled to a distal end of the catheter adapter. ### Claim 14 (depends on 1) The catheter assembly of claim 1, wherein in response to the activator attachment being inserted into the proximal opening of the catheter adapter the first amount, the catheter adapter contacts the set of threads.
