Claim 0:
1. A catheter system, comprising:
a catheter adapter having a proximal end, a distal end, and an interior extending therebetween;
an intravenous catheter having a proximal end coupled to the catheter adapter and comprising a lumen;
a central pathway in fluid communication with the interior of the catheter adapter and the lumen of the intravenous catheter;
a wedge disposed within the catheter adapter and securing the intravenous catheter within the catheter adapter, wherein the wedge comprises an interface surface;
an introducer needle positioned within the central pathway and comprising a sharpened distal tip, a proximal end, a body extending therebetween, and a notch formed through a side wall of the body and in fluid communication with an interior lumen of the introducer needle;
a haptic feature within the intravenous catheter, wherein when the sharpened distal tip is withdrawn past the haptic feature, pressure exerted by the haptic feature on an outer surface of the introducer needle is released, wherein when the sharp distal tip is withdrawn past the haptic feature and the notch is within the wedge, pressure exerted by the haptic feature on an outer surface of the introducer needle is released; and
an indicator provided on the intravenous catheter and having a distal end and a proximal end, wherein when the sharpened distal tip is between the distal end of the indicator and the proximal end of the indicator, the notch is disposed distal to a proximal-most end of the interface surface and proximal to a distal end of the interface surface.
