Claim 0:
1. A catheter system, comprising:
a catheter assembly, comprising:
a catheter adapter, comprising a distal end, a proximal end, and a lumen extending through the distal end of the catheter adapter and the proximal end of the catheter adapter; and
a catheter secured within the catheter adapter and extending distally from the distal end of catheter adapter; and

a needle assembly, comprising:
a needle hub, comprising:
a distal end coupled to the proximal end of the catheter adapter;
a proximal end;
a wall extending between the distal end of the needle hub and the proximal end of the needle hub;
a flashback chamber proximate the wall and extending through the proximal end of the needle hub; and
a through-hole disposed at a distal end of the flashback chamber and within the wall;

an introducer needle comprising a proximal end having an outer diameter greater than a diameter of the through-hole, wherein the introduce needle is press-fit within the through-hole; and
a plug coupled to the proximal end of the needle hub, wherein the plug plugs a proximal opening of the flasback chamber and provides venting of the flasback chamber, wherein the plug comprises a distal end, a proximal end, a lumen extending through the distal end of the plug and the proximal end of the plug, wherein the proximal end of the plug comprises a luer adapter and a septum disposed with the luer adapter.
