1. A catheter system comprising:
a catheter adapter comprising:
a catheter hub comprising a distal end and a proximal end and defining a chamber extending between the distal end and the proximal end;
a septum disposed within the catheter hub;
a catheter extending from the distal end of the catheter hub and in fluid communication with the chamber;
a stabilization platform; and
a needle hub comprising:
a needle configured to slidably fit within the catheter, wherein the needle comprises a distal point having a beveled opening and an annular wall, wherein the beveled opening forms an open bore that extends through the needle, wherein an outer surface of the annular wall comprises an axial groove extending from the beveled opening proximally beyond the septum, wherein the annular wall separates the open bore and the axial groove such that the axial groove does not enter the open bore of the needle;
a needle hub body anchored to a proximal end of the needle,
wherein in an insertion configuration, the proximal end of the catheter hub is removably coupled within a distal opening of the needle hub, and
wherein after placement of the catheter, the needle hub is retracted from the catheter adapter to slidably remove the needle from the catheter and to separate the needle hub from the catheter adapter.
