Claim 6:
7. A catheter system, comprising:
a catheter assembly, comprising:
a catheter hub, comprising a distal end, a proximal end, a lumen extending through the distal end and the proximal end, and a stepped or tapered outer surface disposed between the distal end and the proximal end;
a catheter tube extending distally from the distal end of the catheter hub; and
a push tab and a plurality of ribs extending outwardly from an upper portion of the catheter hub, wherein the plurality of ribs are shorter in height than the push tab and proximal to the push tab, wherein the push tab is proximal to the stepped or tapered outer surface; and

a needle assembly, wherein the needle assembly comprises a needle hub and an introducer needle extending distally from the needle hub and through the catheter tube, wherein the needle hub comprises a first elliptical face and a second elliptical face opposite the first elliptical face, wherein the first elliptical face and the second elliptical face are positioned outwardly from a body of the needle hub, wherein a longitudinal axis of the first elliptical face is angled with respect to a longitudinal axis of the catheter system such that a proximal end of the first elliptical face is positioned upwardly with respect to a distal end of the first elliptical face, wherein a longitudinal axis of the second elliptical face is angled with respect to the longitudinal axis of the catheter system such that a proximal end of the second elliptical face is positioned upwardly with respect to a distal end of the second elliptical face, wherein the first elliptical face comprises a plurality of protrusions arranged along the longitudinal axis of the first elliptical face and angled with respect to the longitudinal axis of the catheter system, wherein the second elliptical face comprises another plurality of protrusions arranged along the longitudinal axis of the second elliptical face and angled with respect to the longitudinal axis of the catheter system.
