Claim 0:
1. An intravenous catheter device comprising:
a catheter assembly having a catheter adapter and a catheter that extends distally from the catheter adapter;
a needle assembly having a needle hub and a needle that extends distally from the needle hub, the needle extending through the catheter adapter and the catheter; and
a safety mechanism having a barrel and a slider that slides within the barrel, a distal end of the slider being coupled to a proximal end of the catheter adapter such that the catheter assembly slides with the slider relative to the barrel, the needle hub being contained within the barrel and being configured to retract proximally within the barrel, wherein the needle hub is retracted proximally within the barrel when the slider slides distally to a trigger point, wherein a proximal end of the slider is configured to form an interference fit with the trigger point to prevent the slider from sliding proximally relative to the barrel.
