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, wherein the central pathway extends through the interface surface, wherein blood is prevented from flowing out of a notch when the notch is within the wedge at the interface surface;
an introducer needle positioned within the central pathway and comprising a sharpened distal tip, a proximal end, a body extending therebetween, the notch formed through a side wall of the body and in fluid communication with an interior lumen of the introducer needle, and a haptic feature; and
