1. A catheter assembly, comprising:
a catheter adapter having a body, the body comprising a distal end, a proximal end, and a side port, wherein an inner surface of the body forms a lumen extending between the distal end and the proximal end, wherein a central axis of a fluid path extending through the side port is disposed at an angle with respect to a longitudinal axis of the catheter adapter, wherein the angle is less than 45°, wherein the inner surface of the body comprises a smooth curve flush with an inner surface of the side port such that there is no catch point at a transition between the side port and the lumen, the inner surface of the side port being generally parallel with a longitudinal axis of the side port, wherein the inner surface of the side port and a distal portion of the inner surface of the body generally parallel with the longitudinal axis of the catheter adapter form a rounded surface;
a wedge disposed within the lumen of the catheter adapter; and
an insert proximate the wedge, wherein the insert is configured to guide an instrument moving from the side port distally through the catheter adapter, wherein the insert comprises a groove extending along an entire length of the insert, wherein the groove is aligned with the side port fluid path such that fluid may flow from the side port fluid path distally through the insert, wherein the wedge comprises a mouth that includes a shape of a truncated cone, wherein a distal end of the insert comprises a tapered portion that contacts an inner surface of the mouth.
